In lithium‐ion batteries, the polymer electrolyte was susceptible to mechanical damage from external stimuli or internal expansion caused, which in turn affected the performances of the batteries. The thermally reversible self‐healing gel polymer electrolyte (DASHPE) based on the Diels–Alder reaction was prepared to solve the above problems. The DASHPE electrolytes exhibited good flexibility and self‐healing...
Lithium, is the most ideal anode material for lithium‐based batteries. However, the overgrowth of lithium dendrites and the low lithium‐ion diffusion rate at low temperatures limit the further application of lithium metal anodes. Here, the applied magnetic field is introduced inside the lithium metal anode by using a novel magnetic metal‐organic framework as a current collector. The magnetic field...
Aqueous rechargeable Zinc (Zn) batteries incorporating MnO2 cathodes possess favorable sustainability properties and are being considered for low‐cost, high‐safety energy storage. However, unstable electrode structures and unclear charge storage mechanisms limit their development. Here, advanced transmission electron microscopy, electrochemical analysis, and theoretical calculations are utilized to...
