That list would be interesting. The realy hard part is implimentation. Proving, scaleability and ability to fit into a standard package/voltage unit. Bonus points if it can be manufactured useing existing machinery.And another new concern is waste disposal, which will be highlighted by the existing competetors who have a complete world wide recycling infrastructure in place. The prospect of true solid state battery storage, in the form of "supper caps", shows promice. And is keeping everyone aware that bieng the developer of the very best forgetten orphan technology is realy realy not the thing worth pushing for. Would be battery magnates, are like spiders in a jar. Not that any of that is detering development of new ideas, as the market for stored energy is truely vast, and growing. But early adopters and investors will have to do there own research.
