Improving Fast‐Charging Performance of Lithium‐Ion Batteries through Electrode–Electrolyte Interfacial Engineering by Seungwon Kim, Sewon Park, Minjee Kim, Yoonhan Cho, Gumin Kang, Sunghyun Ko, Daebong Yoon, Seungbum Hong, Nam‐Soon Choi

“…Here, a synthetic additive called isosorbide 2,5‐dimethanesulfonate (ISDMS) with a polar oxygen‐rich motif is reported that can competitively coordinate with Li+ ions and allow the entrance of PF6– anions into the core solvation structure. The existence of ISDMS and PF6− in the core solvation structure along with Li+ ions enables the movement of anions toward the anode during the first charge, leading to a significant contribution of ISDMS and LiPF6 to SEI formation. …”
