Lithium-ion Batteries for the Hybrids?

Jul 11, 2009

The recent Hitachi's announcement that beginning next year and by 2015 it will increase its Li-ion battery production by 70 fold for hybrids is quite significant for the Li-ion battery market. Until now, most analysts thought that there was no real potential for use of Li-ion batteries in Hybrid Electric Vehicles (HEVs). They erroneously believed that Nickel-Metal Hydride (NiMH) batteries were the best choice for today's HEVs, whereas Li-ion batteries were reserved for tomorrow's Plug-in Hybrid Electric Vehicles (PHEV), Range Extended Electric Vehicles (REEVs) and Battery Electric Vehicles (BEVs).

This argument, of course, never made sense. It rested on the unreasonable two-fold assumption that Li-ion batteries are not ready for prime-time and that plug-ins (and, for that matter, REEVs and BEVs) are a scam. For one thing, Hitachi's notice tears apart the first half of the above contention. For another, Toyota's latest decision to begin mass-producing PHEVs by 2012 and Nissan's conviction that "now's time to go electric" completely demolish the second half of it. Indeed one should not be surprised since PHEVs can be really thought of as an extension of HEVs. So if Li-ion batteries are to be used quite soon in plug-ins and both range-extended and battery EVs, then why not utilize them now for conventional hybrids as well? The new General Motors appears to have understood this. It just asked Hitachi to produce Li-ion batteries for its 100,000 hybrids that it plans to sell from next year.

Taken together, this only means that both NiMH and Lead Acid (LA) battery makers have many reasons to worry nowadays. And some of them, perhaps aided by their government, appear to have started to take some actions. In China, for example, they may be behind their government's decision to impose restrictions to lithium-ion battery vehicles. At first sight, these constraints may seem somewhat astonishing, considering that China holds one of the most advanced lithium-ion battery car makers of the world, namely Build your Dreams (BYD). However, they may be indeed part of a rather rational approach to help a number of other car producers that for the last five years or so have been heavily investing in NiMH and LA battery technologies for their different cheap plug-ins and electric vehicles, already running on Chinese roads and/or getting ready for export to other countries.

While I doubt anything like it could happen in Japan or in the U.S., one should be aware that all these recent events will begin to change dramatically the battery car market as a whole. In this connection, Hitachi's approach is likely to be followed by other battery makers in Japan and elsewhere. But this may be a short-lived approach. We will not have to wait too long until the major car makers of the world realize that mass-producing REEVs and BEVs (rather than HEVs and PHEVs) is the correct way forward. The new GM and Nissan seem to be quite clear about it, while Toyota also appears to be moving (albeit cautiously) in the right direction.

I have previously explained why I thought it was in Toyota's (and Honda's) interest to behave this way. But, given both recent GM's re-launch and Nissan's renewed financial situation after having been granted a $ 1,6 billion loan to develop advanced Li-ion batteries for its new pure electric car, to retain its largest share in the automobile market of the world, Toyota will probably need to modify significantly its current conservative business strategy.

Bolivia: The New Saudi Arabia of the World? A Review of Recent Facts

Jun 30, 2009

 

In a previous blogI argued that three conditions needed to be met for Bolivia to become the “New Saudi Arabia of the World”. First, the electric car rush should start along with the launch of GM´s Volt. Second, Bolivia had to begin producing lithium carbonate in a proportion appropriate to the world´s needs. Third, increases in lithium prices should not make the production of other lithium resources (e.g. spodumene) commercially viable.

 

A recent review of facts gives rise to the following conclusions. First, the electric car rush along with the launch of the Volt is on schedule. Second, given Bolivia´s latest decision to go on its own to develop its lithium resources, it appears that the country has chosen the most difficult route to supply lithium carbonate to the world. And, third, this erratic behavior is in fact encouraging the production of other spodumene lithium resources in other parts of the world.

Under these circumstances, Bolivia seems to start losing sight of its golden opportunity to become the “New Saudi Arabia of the World” while postponing the inauguration of the affordable electric vehicle era in the planet.

Bolivia: The New Saudi Arabia of the World?

Mar 16, 2009

In recent months there has been a real avalanche of news and comments from the international press about the lithium reserves of the Salar of Uyuni. In this context, Bolivia has been compared with Saudi Arabia in reference to the possibility that the country will become in the next few years a major energy source on earth. However, it is too early to tell whether Bolivia will become the new Saudi Arabia of the world. This depends on at least three factors.

First, the electric car rush must start to begin with. In order for this to happen the launch of GM´s Volt is crucial. It is important to remember that it was precisely GM the first global car maker to announce in January 2007 that by 2010 it would introduce the first mass-produced lithium-powered plug-in hybrid electric cars into the market. This should not diminish the importance of the recent BYD and Chery cars launching in China, pointing only to the magnitude of the US market for one of the world´s most revolutionary technological innovations of the last 100 years.

Second, Bolivia has to start producing lithium carbonate in a proportion appropriate to the world´s needs. This, of course, is not an easy task considering both the country´s lack of experience in producing the metal and the government´s decision not to allow any foreign assistance or investment in this endeavor.

Third, increases in lithium prices (emerging perhaps from an early temporary supply crunch) should not make the production of other lithium resources (e.g. spodumene) commercially viable.

The Advent of the Lithium Era in Bolivia

Apr 05, 2008

Juan Carlos Zuleta Calderón *

Last Tuesday, Evo Morales, President of Bolivia, announced the construction of a small pilot plant to produce lithium carbonate at the delta of Rio Grande in Uyuni, where it is believed are laying the richest brines of lithium of the world, thereby inaugurating the lithium era in Bolivia. As is well known, with its 5,4 million tons of lithium (metal equivalent), Bolivia holds around 50% of world reserves of the lightest and most electro-negative metal of the planet.

The small pilot plant will cost 5.7 million US dollars. As President Morales indicated, this is only the first phase of a larger project aimed also at industrializing all the non-metal resources (e.g. boron, potassium, magnesium, and sodium) of the Uyuni Salt Lake in the Department of Potosi, which has been estimated to cost 150 million US dollars, an amount that at present the Bolivian State is willing to invest since its return is granted and this will ensure that Potosi becomes once again the center of the country´s economy.

This announcement leaves aside, at least for the time being, any other supposition that the political situation of the country could jeopardize the provision of lithium to the world in times of an escalating demand for the resource resulting to a great extent from an apparently irreversible transition of the global automobile industry to electric propulsion.

The Obama Audit Task Force and the Volt

Apr 18, 2009

In several articles published over the last year and a half or so both in Bolivia and the United States I have advocated GM‘s Volt as a technological innovation that would revolutionize the global car industry. So, on March 30 2009 I was astonished by the main conclusion of the Obama Audit Task Force (OATF) regarding the Volt:

“GM is at least one generation behind Toyota on advanced, “green” powertrain development. In an attempt to leapfrog Toyota, GM has devoted significant resources to the Chevy Volt.”

This conclusion only reflects the OATF´s failure to understand what advanced “green” car technology really means.

In a recent blog I have argued that by relying on (obsolete but still commercially viable) nickel-metal hydride batteries for their conventional hybrids, both Toyota and Honda have been following a similar but rather cautious and conservative approach to a lithium-based transition to electric propulsion in the global car industry.

This entirely rational behavior not only comes down to a different business strategy than that of their main competitor: General Motors (GM); it also implies their lagging behind GM insofar as electric automobile technology.

In fact, while conventional hybrids have played a big role in raising driver´s consciousness over the last ten years or so, everybody now agrees that Plug-in Hybrid Electric Vehicles (PHEVs), Range Extended Electric Vehicles (REEVs) and Battery Electric Vehicles (BEVs) are the obvious steps forward. Something all these new EV technologies share in common is their dependence on lithium.

Both Toyota and Honda know that for sure; that is precisely why they are now investing a great deal in lithium. But given the critical situation of the American motor giant, it simply does not (and did not) make any sense for them to become GM´s technology followers or even leapfroggers.

Had they decided to become followers or leapfroggers of GM, they would have had to lose part of what they seem to value the most nowadays: their reputation. One just needs to remember that at the time GM made its Volt announcement, it was already facing severe financial problems and Toyota and Honda were still the second and third largest automakers of the world (As of today, Toyota is first and Honda remains third).

It was then probably wise for Toyota to stick – at least for the time being - with its much proven and praised Prius technology and let other car makers undergo the painful “trial and error” process of the new way of doing things. One must keep in mind also, that to leapfrog GM, Toyota first would have had to kill the Prius.

In a similar vein, it also made sense for Honda to be inclined towards a two-step approach to electrification: first, emulate the know-how (i.e. the Prius technology) advanced by a much more respected firm (Toyota) than GM and, second, come up with something revolutionary, something beyond lithium; the hydrogen-powered FCX Clarity model, for instance.

Of course one should not be surprised if, also as part of their business strategy, sometime down the line both Toyota and Honda introduce some sort of lithium-powered electric cars into the market. As I have recently commented on Seeking Alpha, however, this may occur only at the expense of a technological lag.

Hence the OATF in its recent March 2009 report did not appear to have a clue in terms of what advanced “green” car technology really means. Perhaps some consumers in the US and the UK government could have provided the Task Force with some valuable hints in this regard.

Why Toyota and Honda Dislike Lithium?

Mar 29, 2009

Over the last two years or so, Toyota and Honda have been following a similar approach to a lithium-based transition to electric propulsion in the car industry. Indeed they have been rather conservative and cautious. In January 2009 Toyota announced, for example, that its new Prius will still use nickel-metal hydride batteries while not discarding the possibility to do some testing with lithium-ion batteries for small fleets. Honda has been even tougher. In its recently launched Insight model, it has simply ignored the latest breakthroughs in lithium-ion battery technology essentially sticking to the same chemistry used by Toyota. As of today, the two Japanese car companies are engaged in a price war which has prompted Toyota to announce the launching of a hybrid version of its small car Yaris to counterstrike the apparently recent market success of Honda's Insight. But why are they both staying in the lower-end of technology evolution regarding electric propulsion? In other words, why are they still betting on conventional hybrid technology while the rest of carmakers all over the world are aiming at Range Extended Electric Vehicles (REEVs) and Battery Electric Vehicles (BEVs)?

Often times during 2007 and 2008 Toyota's CEOs have argued that lithium-ion is not yet a proven technology for electric cars and that there are problems with lithium availability on earth to ensure an actual replacement of petroleum-based vehicles. These arguments have been seriously weakened by both recent breakthroughs particularly in lithium Ferrum Phosphate battery technology that is already powering two mass-produced REEVs in China and announcements by the world's major lithium suppliers in Chile during the January 2009 Lithium Supply & Markets Conference that there is indeed sufficient lithium on earth to warrant the electric car revolution. Surprisingly, as a recent news article from the United Kingdom indicates, in 2009, Toyota appears to start moving ahead with lithium technology, but again one needs to wonder whether this is a real change in its business strategy.

At first sight, Honda's approach has been more consistent than Toyota's in terms of what comes first and what comes thereafter. To Honda, electric cars only make sense if they are powered by hydrogen. That is why it has ruled out any possibility whatsoever to launch lithium-powered plug-in hybrid or pure electric cars in the near future. Nevertheless, earlier this year it has announced a joint venture with Yuasa to produce lithium-ion batteries. One simply wonders why Honda is investing heavily in lithium while at the same time is questioning this type of technology. Are there any specific reasons for such behavior?

In this context, I can only conjecture that both Toyota and Honda may be playing the same game, one aimed at precluding General Motors from succeeding in its attempt to lead the electric car revolution. I am convinced that the launch of the “Volt” car by GM is one (if not the most) important condition for the inauguration of electric propulsion in the world. If this does not occur or it is somewhat delayed, then Toyota and Honda have much to gain because that will necessarily postpone the arrival of the sixth techno-economic paradigm with lithium as its main factor and will help them make more profits out of a rather obsolete but still commercially viable battery technology until the new emerging battery technology is finally introduced into the market. This is most relevant now following today's New York Times news that the chairman and executive chief of General Motors, Rick Wagoner, is resigning, right in the middle of a serious turmoil at this firm. So when it comes to lithium-ion battery technology, Toyota and Honda may in fact need to be conservative and cautious at least for the time being; it may be in their own interest to behave this way.
