In this work, an in situ liquid-phase process to prepare the NCM811 composite cathode (LP-cathode) with low porosity and tortuosity. ASSLBs with LP-cathode are able to retain excellent electrochemical performance even with high CAM content and loading, which holds promise for addressing the challenges associated with achieving high energy density,...

Cation-disordered CuGeSiP3 demonstrates higher electronic and ionic conductivity and greater tolerance to volume change than both CuGe2P3 and Ge due to the increased structural entropy, thus offering better performances. Abstract While germanium-based anodes for Li-ion batteries (LIBs) have potential to offer high energy density, their commercialization...

Benefiting from the formation of high-entropy(HE) and multiphase structures with the introduction of multi-transition metals, obviously improved performance is obtained compared with low-entropy multiphase structure and HE single-phase cathode. The weighted average ionic radius of multi-transition metals is demonstrated critical for the phase formation...

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...
