Description

technical field [0001] The invention relates to the technical field of solid electrolytes, in particular to a lithium borohydride / decaborane solid electrolyte and a preparation method thereof. Background technique [0002] Today, lithium-ion batteries have become an integral part of everyday life in today's society. Lithium-ion batteries have the advantages of high specific energy, high specific power, high charge and discharge efficiency, and small self-discharge, and are widely used in electronic products. Nonetheless, substantial improvements in energy density and safety performance are still required for electric vehicles and grid energy storage. [0003] Traditional lithium-ion batteries use electrolytes made of organic solvents or gels. This electrolyte has high lithium ion conductivity, but it is prone to leakage. At the same time, these electrolytes will form lithium dendrites during use, causing the battery to short circuit. , causing a fire. All solid-state batt...
