The trade-off between the mechanical strength and ionic conductivity of solid polymer electrolytes at both room temperature and elevated temperatures is broken by utilizing extremely strong poly(p-phenylene benzobisoxazole) (PBO) as the backbone and polyethylene oxide (PEO) as the ionically conductive network. The PBO/PEO solid polymer electrolyte...

A N-doped carbon framework embedded with a plethora of CuS nanocrystallites is designed as a host for Li2S in an all-solid-state battery. CuS lowers the activation barrier of Li2S to sulfur conversion, enhancing the kinetics and Li+ transport. The as-assembled batteries achieve high areal capacity and long cycle life with good cycling stability. ...

Bismuth@C (Bi@C) nanosheet arrays are fabricated via a facile galvanic replacement strategy coupled with an in situ dopamine coating and annealing route. Due to the unique nanosheet array design, this Bi@C anode could effectually ameliorate the volume fluctuation, shorten the diffusion distance of Na+ ions, and thus facilitate the electrochemical...
