Unfortunately, history shows that new battery chemistries are a dime a dozen. It's commercialization and manufacturing at scale that's the real bottleneck. Look at what happened to Aquion, which raised $190 million for their salt water battery:
Research and development, and building out manufacturing infrastructure for something nobody wanted. Looks like they were killed by the falling costs of Lithium Ion. If you plan to be 50% cheaper than Li in 4 years and then 3 years in Li costs have halved, you’re in trouble.
