1. Introduction With the rapid development of the lithium-ion battery industry, concerns over safety and stability during battery use have grown significantly. The primary causes of performance degradation in lithium-ion batteries can be summarized as loss of active lithium, loss…
1. Research Background Metallic lithium, with its exceptionally high specific capacity (3,860 mAh g⁻¹), has garnered intense interest for next‑generation batteries. Solid‑state lithium batteries (SSLBs), by virtue of their safety and potential energy‑density advantages, are strong contenders to replace commercial liquid‑electrolyte Li‑ion…
1. Author Information and Article Abstract In 2017, the J.R. Dahn research group investigated silicon anode pouch cells using in-situ characterization methods to measure volume, stress, and thickness changes of electrodes during cycling. By combining experimental data with computational analysis,…
1. Research Background In recent years, with the rapid expansion of the new energy vehicle market powered by lithium-ion batteries (LIBs), the number of retired LIBs is expected to increase significantly over the next 5–10 years. Therefore, lithium battery recycling…
1. Intoduction Formation is a crucial step in battery manufacturing. During the formation process, the negative electrode first develops a solid electrolyte interphase (SEI), after which lithium ions traverse the SEI to intercalate into the negative electrode particles. Both of…
1. Abstract The expansion behavior of silicon-carbon cells is primarily attributed to the volumetric expansion of the silicon component. Excessive accumulation of irreversible expansion during cell cycling can lead to significant capacity degradation. Current industry strategies for enhancing the cycling…
