Abstract
In the development of lithium ion batteries (LIBs) with higher energy density and safety, solid-state lithium batteries (SSLBs) have attracted widespread attention. However, even in SSLBs, when metallic lithium is used as the anode, lithium dendrites can still form during the lithium-ion deintercalation process, leading to poor cycling performance of the battery. Herein, lithium-boride (Li-B) alloy with a layered three-dimensional skeleton structure was synthesized and investigated as anode for SSLBs. Due to the stability of the special three-dimensional skeleton structure, the deintercalation of lithium ions does not cause the collapse of the material structure. Thus, compared to the metallic lithium anode, the Li-B alloy exhibits higher discharge specific capacity and better cycling performance (when using the as-prepared lithium-rich manganese-based (Li1.2Ni0.2Mn0.6O2) as the cathode material, the initial discharge capacity of the SSLBs is 209 mAh g–1, and when using LiFePO4 as the cathode material, the initial discharge capacity is 192 mAh g–1, with a capacity retention rate of 82% after 50 cycles).
