Abstract

The binary system, xLi3NbO4-(1 - x)LiVO2, was first examined as an electrode material for rechargeable lithium batteries. The sample (x = 0.43) crystallizes into a cation-disordered rocksalt structure and delivers a reversible capacity of ca. 230 mA h g(-1), which originates from V(3+)/V(5+) redox with electrochemically inactive niobium ions.

摘要

二元体系xLi3NbO4-(1 - x)LiVO2首次作为可充电锂电池的电极材料进行研究。样品（x = 0.43）结晶为阳离子无序岩盐结构，并具有约230 mA h g(-1)的可逆容量，这源于V(3+)/V(5+)氧化还原反应，其中铌离子在电化学上是惰性的。
