LG Energy Solution revealed this week that it has pivoted away from its existing lithium ion technology towards LFP (lithium iron phosphate) chemistry, which is rapidly gaining popularity because it is cheaper and less volatile than other Lithium chemistries such as NCM (Nickel Manganese Cobalt Oxide). Just a couple of years ago LG was continually attacking LFP in brochures and in blogs on its website on the basis that the NCM cathode was simply more effective. Most lithium ion players are seeing the argument shift to one of thermal runaway and safety versus higher energy density, especially where grid batteries are concerned and where the highest energy density is not needed. Tesla has said it will use the highest energy…
