With the rapid demand for lithium-ion batteries due to the widespread application of electric vehicles, a significant amount of battery electrode pieces requiring urgent treatment are generated during battery production and disposal. The strong bonding caused by the presence of binders makes it challenging to achieve thorough separation between the cathode active materials and Al foil, posing difficulties in efficient battery material recycling. To address this issue, a plasma-ultrasonically combined physical separation method is proposed in this study. This method utilizes plasma-generated excited-state radicals assisted by ultrasonic waves to separate active materials and current collectors. The results indicate that the binders are effectively decomposed under plasma treatment at 13.56 MHz, 100 W, and 10 min in an oxygen atmosphere, resulting in a separation efficiency of 96.8 wt % for the cathode materials. Characterization results demonstrate that the morphology, crystal structure, and chemical composition of the recycled cathode active materials remain unchanged, facilitating subsequent direct restoration and hydrometallurgical recycling. Simultaneously, the Al foil is also completely recycled for subsequent reuse. Compared with traditional methods of separating cathode active materials and aluminum foil, the method proposed in this study has significant economic and environmental potential. It can promote the recycling of battery materials and the development of sustainable transportation.

“…[13] Besides lithium dendrites, the defects introduced during the manufacturing process are another major cause of internal short circuits. [14,15] According to the statistics, 52% of fire accidents in electric vehicles are caused by internal short circuits. [16] External short circuit, usually caused by incorrect operation, water immersion, or battery leak, accounts for 26% of battery fire accidents.…”

Lithium–sulfur (Li–S) batteries are one of the most competitive candidates for high‐energy‐density batteries. However, the high energy density and high reactivity of the lithium anode and sulfur cathode make the safety issues of Li–S batteries particularly prominent. Herein, an early warning strategy for the short circuits in Li–S batteries is explored by integrating an in‐plane electron‐conductive separator. The internal short circuits caused by lithium dendrites or manufacturing defects can be quickly and accurately predicted before catastrophic thermal runaway, with enough time to take rescue measures. The separator with high thermal conductivity also facilitates the heat dissipation of the cell, thus reducing the risk of thermal runaway under abuse. The fast and reliable early warning strategy based on the in‐plane electron‐conductive separator builds the Great Wall of active defense against inherently unsafe Li–S batteries.
