Nano-scaled hydrophobic confinement of aqueous electrolyte by a nonionic amphiphilic polymer for long-lasting and wide-temperature Zn-based energy storage

Trace addition of a hydrophilically tuned nonionic amphiphilic polymer additive enables hydrophobic confinement of aqueous electrolyte that considerably prolongs the cycle life of aqueous Zn-ion devices and widens the temperature of operation.
