Herein, the effects of charge rate in coin cells containing NMC532/1506‐T graphite are investigated. The cells are cycled at room temperature using charge rates of 1‐, 2‐, 4‐, and 8‐C and discharged at the 1‐C rate for 50 cycles. The amounts of lithium and LiF are found to be highly correlated with charge time. Three decomposition products are identified in the organic electrolyte. The proposed, empirical formulae for these compounds are C₁₄H₃₃O₁₅P₃, C₁₆H₃₇O₁₅P₃, and C₁₁H₂₂O₇PF; all are most likely organophosphates formed by the reaction of organic electrolyte decomposition products with LiPF₆ or P(=O)F₃. The relative concentrations of these organics do not display sensitivity to charge rate. These results imply that a new performance fade mechanism is not introduced by electrolyte decomposition.

锂离子电池极速充电：对阳极和电解质的影响

在此，研究了含有NMC532 / 1506-T石墨的纽扣电池中充电速率的影响。电池在室温下使用1、2、4和8C的充电速率循环，并以1C速率放电50个循环。发现锂和LiF的量与充电时间高度相关。在有机电解质中鉴定出三种分解产物。这些化合物的建议经验公式为C ₁₄ H ₃₃ O ₁₅ P ₃，C ₁₆ H ₃₇ O ₁₅ P ₃和C ₁₁ H ₂₂ O ₇PF; 所有这些都是有机电解质分解产物与LiPF ₆或P（= O）F ₃反应形成的有机磷酸盐。这些有机物的相对浓度对充电速率不敏感。这些结果暗示电解质分解不会引入新的性能衰减机制。
