摘要

最近，Gao等人在Nature上报道了一种非破坏性的锂供应方法，打破了锂离子电池现有的寿命限制。通过机器学习发现的三氟甲烷磺酸锂（LiSO2CF3）作为外部锂源，使氧化铬阴极能够提供1,192 Wh kg - 1的高能量密度。同时，石墨|LiFePO4电池在11818次循环后的容量保持率为96.0%。

Shatter existing lifetime limit of lithium-ion battery

Recently in Nature, Gao et al. reported a non-destructive lithium supply method for shattering the existing lifetime limit of lithium-ion batteries. Lithium trifluoromethanesulfinate (LiSO₂CF₃), discovered through machine learning, acts as an external lithium source, enabling a chromium oxide cathode to deliver a high energy density of 1,192 Wh kg⁻¹. Meanwhile, the graphite|LiFePO₄ cell displayed a capacity retention of 96.0% after 11,818 cycles.
