摘要

Abstract

Although silicon is a promising anode material for high-energy-density lithium-ion batteries

the huge volume change during the cycling leads to collapse of the electrode structure and fast degradation

particularly for the high-mass-loading electrodes. This has severely hindered its practical application. Here

a crosslinked polymer gel electrolyte is developed for high-mass-loading Si electrode. The gel electrolyte was fabricated by

in situ

polymerization method using methyl methacrylate and

′-methylenebisacrylamide as the monomer and crosslinking agent

respectively. It forms hydrogen bonds with hydroxyl groups on the surface of silicon anode to fix silicon particles and shows high oxidative stability to be compatible with high voltage cathode. With such gel polymer electrolyte

a high-mass-loading Si anode at 3.5 mg·cm

–2

achieves a largely improved cycling stability

with a high reversible capacity of 1462.4 mAh·g

–1

. Furthermore

full cells using the high-mass-loading Si anode and LiNi

0.8

0.1

cathode demonstrate exceptional cycling performance with a high capacity retention of 75.8% after 1000 cycles a

t 1 C

and stable cycling even at a high temperature of 60 °C. Our findings provide an effective strategy to promote the practical application of high-mass-loading Si anode for high energy density lithium ion batteries.
