摘要

在中等浓度的酯类电解质中，线性酯烷基链越长，K+溶解越容易。在碳酸乙酯+碳酸丁酯甲酯混合物中加入2.4 M KFSI电解质，石墨阳极的容量高达261 mAh g-1，在2℃下循环500次后容量保持率为93%。

Tailoring the alkyl chain length of linear esters in moderately concentrated electrolyte for a high-performance graphite anode in K-ion batteries†

K⁺ desolvation in moderately concentrated ester electrolytes becomes easier with a longer alkyl chain of the linear ester. An electrolyte of 2.4 M KFSI in an ethylene carbonate + butyl methyl carbonate mixture renders a graphite anode with a high capacity of 261 mA h g⁻¹ and 93% capacity retention after 500 cycles at 2C.
