Clearly, a big lithium-ion battery powering an electric car will become far hotter than that when it’s being used, and so car makers adopt systems to keep the batteries from overheating. This works much better than the early air-cooling systems for EV batteries, as any owner of an original Nissan Leaf can attest. Liquid cooling essentially unlocked much better battery performance. Would that unlock even better performance? So any improvements that you can make to lithium-ion battery operation, which is really what we’re talking about here, will sustain the technology well into the future.”
