All-solid-state batteries designed for operation under extreme cold conditions.

A pressing need for enhancing lithium-ion battery (LIB) performance exists, particularly in ensuring reliable operation under extreme cold conditions. All-solid-state batteries (ASSBs) offer a promising solution to the challenges posed by conventional LIBs with liquid electrolytes in low-temperature environments. In this study, leveraging the benefits of amorphous solid-state electrolytes (SSEs) xLiN-TaCl (1 ≤ 3x ≤ 2), we develop ASSBs capable of functioning effectively under extreme cold conditions.

Novel Amorphous Nitride-Halide Solid Electrolytes with Enhanced Performance for All-Solid-State Batteries.

Solid electrolytes (SEs) in all-solid-state batteries (ASSBs) are garnering considerable attention for their potential applications in next-generation energy storage systems. Amorphous SEs with dual-anion hold great promise for achieving favorable performance, such as high ionic conductivity and good compatibility with electrodes within ASSBs. Here, we discover a family of amorphous nitride-halide SEs, LiMClN (M=Ta or La, 1≤3x≤1.

Effect of PVP Coating on LiMnBO Cathodes for Li-Ion Batteries.

LiMnBO is a potential cathode for Li-ion batteries, but it suffers from a low electrochemical activity. To improve the electrochemical performance of LiMnBO, the effect of polyvinyl pyrrolidone (PVP) as carbon additive was studied. Monoclinic LiMnBO/C and LiMnBO-MnO/C materials were obtained by a solid-state method at 500 °C.
