SHANGHAI/HONG KONG (Reuters) - Tesla Inc is in talks with Chinese battery maker EVE Energy Co to add the firm to its Shanghai factory supply chain, four people familiar with the matter said, as it seeks to boost procurement of lower cost batteries.

EVE makes lithium iron phosphate (LFP) batteries, which are cheaper to produce because they use iron instead of more expensive nickel and cobalt.

But LFP batteries generally offer a shorter range on a single charge than the more popular nickel/cobalt alternative.
