Maybe the next big disruption is not about making better batteries based on Li (Lithium) but to ditch Li for most mass use purposes and go with a different material, e.g. Na (Natrium, vulgar name: Sodium)… which unlike lithium is extremely abundant. It would (at least in its early less optimized versions) have a slightly lower energy density at about 200 Wh/kg compared to the current best lithium-based state of the art batteries, but still be in a similar ballpark and easily enough for many applications, especially given the much cheaper price.
Some manufacturers (e.g. CATL in China) are apparently already ramping up for Na battery mass production.
