Abstract

Herein, we employed Bi and Sb as the negative electrode in all solid-state lithium-ion batteries (LIBs) using LiBH₄ as the solid-state electrolyte. The composite anode materials with acetylene black (AB) and LiBH₄, prepared by high energy ball-milling, have shown extremely high stability with a high coulombic efficiency of 90-99% over a number of cycles. The gravimetric capacity decayed by only 18 and 5% as compared to the initial volumetric capacity of 4681.7 and 4393.4 mA h cm^-3 for Bi and Sb anodes respectively.
