Lithium metal batteries

Salt-philic and solvent-phobic

The lack of long-term cyclability poses a serious challenge for lithium metal anodes. Now, a lithium anode coated with a side-chain-engineered polymer — which contains salt-philic and solvent-phobic moieties — is reported to regulate the electrode–electrolyte interphase, thereby prolonging its cycle life.
