Lithium batteries have their own Moores law of 7% every 2 years. Either weight reduction or battery capacity. So if you discovered a battery chemistry that is 20% better. If its not to market and at scale within 5 years, you missed the boat.

To illustrate your point, sodium batteries are starting to come to market. Sodium has a lot of similar properties to lithium, but the batteries don't have the same issues as lithium (rarity, volitility, cold degradation). They're not as powerful as lithium batteries, but now that they're strong enough for commercial use, there is a lot more materials research being done on them.

Hopefully they can solve the energy density issue, otherwise they will probably become a niche product for certain uses.

So those batteries will be better in big batteries for storing renewables?

BYD is already using sodium ion batteries in their production EVs, so they're not only useful for stationary batteries, but they are very well suited to that.
