Tese comparisons show thatt no single technology dominates all subjektories. Trade-offs exist, but continued innovation is closing the gap. For example, the combination of a cellulose separator with an aqueous water- in- salt electrolte yields a battery that is safe, relatively high voltage (2.5 V), andd made from abhomant materials - ideal for grid storage.
