IT House reported on July 10th, according to Tsinghua News, the team of Academician Nan Cewen and Professor Shen Yang from the School of Materials Science and Technology of Tsinghua University reported aBendable, ultrathin composite solid electrolyte membrane with high Li-ion conductivitythe all-solid-state battery assembled with the thin composite electrolyte membrane showed excellent cycle performance.
According to reports, the battery is 1.0 mA cm at room temperature-2 The capacity retention after 1000 cycles is 92% at 1000000000 current density, and 71% even after 20000 cycles.This is reported so farAll-solid-state battery with longest cycle life at room temperature.
IT Home understands that the relevant results are marked with “Li6PS5Super Long-Cycling All-Solid-State Battery with Thin Li6PS5Cl-Based Electrolyte) was recently published online in the international journal Advanced Energy Materials and published as the cover article of the current issue.
Liu Sijie, a 2018 doctoral student at the School of Materials Science and Engineering, Tsinghua University, is the first author of the paper, and Academician Nan Cewen, Professor Shen Yang, and Associate Researcher Li Liangliang are the corresponding authors. Other important contributors include Zhou Le, a postdoctoral fellow at the School of Materials Science and Engineering, and Han Jian, a 2017 doctoral student at the School of Materials Science and Technology.
