I picked up on TechCrunch that Tesla have just signed a deal to supply Mercedes Benz with their Litium Ion batteries. MB are likely to make electric versions of the A and B class vehicles as soon as 2010 along with an electric version of the Smart. If this deal is anything to go by, it seems that Tesla’s technology is going to be in demand. I’ve just been on a poll on TechCrunch which is currently showing that 78% of voters think Tesla will have a bigger business in 5 years time selling it’s batteries than making and selling it’s own cars. A case of a real “sweet spot” technology if I’m not mistaken.
