Abstract

A facile strategy was developed to stablize 3D hosts for lithium metal anodes in carbonate electrolytes, which enables lithium metal batteries with improved Coulombic efficiency (∼99%) and prolonged cycle lifespan (96% retention over 300 cycles) under the conditions of high areal loading (3 mA h cm-2) and low N/P ratio (4).

摘要

人们开发了一种简便的策略来稳定碳酸盐电解质中锂金属负极的三维主体结构,这使得锂金属电池在高面负载(3 mA h cm-2)和低氮/磷比(4)的条件下具有更高的库仑效率(约99%)和更长的循环寿命(300次循环后保持96%)。
