It's estimated that when commercialized, this could bring the cost of a 300-mile range EV down to as little as $20,000. The performance gains come from a special manganese-rich cathode and silicon-carbon nano-composite anode combination. The battery maker is also partly owned by GM, which unsurprisingly means we're likely to see these very cells in its EVs in the future.
