Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
Prevention of mechanical and finally electrochemical failures of lithium batteries is a critical aspect to be considered during their design and performance, especially for those with high specific capacities.
Suppression of anode internal failure The investigation of the anode failure mechanism is considered as a foundation for more robust and durable anodes for next-generation lithium-ion battery.
An attractive phenomenon of the lithium plating is detected. Electrolyte leakage is one of the typical faults that lead to battery failure, and its failure mechanism is still ambiguous. Therefore, it is crucial to investigate the experimental method and failure mechanism of lithium-ion battery electrolyte leakage.
During the insertion and deinsertion of the lithium ions, expansion and contraction occur in the anode material, which leads to the volumetric changes. Subsequently, cracks are gradually formed, resulting in the anode fracture ( Fig. 2 ). As a result, anode failure takes place inevitably and reduces the cycle life of the lithium-ion battery.
