Continental wants to start producing lithium ion cells
Continental, like its arch rival Bosch, is striving to stay relevant in a changing automotive landscape by expanding into new technology areas for hybrid and electric drive vehicles. One technology both companies are pursuing aggressively is lithium ion batteries. Continental will be supplying packs for Mercedes Benz mild hybrid vehicles beginning in 2009. Continental is also one of the development suppliers for the Chevrolet Volt program. So far Continental has partnered with cell suppliers like A123 Systems and Johnson Controls-Saft while focusing pack integration. But like Bosch, Continental wants to start manufacturing cells as well, either by doing it in-house or buying another supplier like A123. The German supplier has already purchased a stake in Enax, but that company only has capacity for small series production. At the moment lithium ion technology is changing so fast that Continental is keeping its options open but Karl-Thomas Neumann, head of powertrain and chassis operations told Reuters that at some stage the company would likely settle on a single partner or acquisition.[Source: The Guardian]

I have to admit I haven't been keeping-up on the intricacies of battery design, but aren't Lithium-Ion batteries the ones that tend to run very hot and have possible combustibility issues?
I thought Lithium-Polymer were much more suited for automobile applications?
Then again, I would hope that major companies banking millions of dollars on R&D of the technology would know better than I do...

There are many different variations on Lithium Ion battery technology - using cobalt oxide or iron phosphate or lithium titanium spinel or manganese oxide, and more variants are on the way like the silicon nanowire version. Even the Lithium polymer battery is, technically speaking, a lithium ion battery but with a solid rather than liquid electrolyte.
The cobalt oxide version is the one that has a problem with heat - if the cobalt oxide gets too hot, it breaks down and releases oxygen, which in turn ignites the hydrocarbon electrolyte and the lithium. The other variants don't have that problem, and are much more heat resistant. But the LiIon Cobalt Oxide batteries are still in common use as they currently have the highest energy density.

ChrisM - great post! It's good to see people here that actually know something instead of spouting off on things they know nothing about.
Vote this guy up!
