Auto makers are pushing now for start stop technology in order to reduce emissions during the urban driving cycle. It will be another very important market for the Lithium based batteries apart from Electric Cars and Plug-In Hybrids. Porsche is already using Lithium batteries in some of its models with CEs. The price/quality as always will determine the adoption rate here.

New lithium battery technology is at the heart of this revolution and it will be spreading fast. GM and Nissan both are struggling to deliver and meet demand of all early adopters who placed their orders now and it is e very good news for all of us."
