LiZnVO4 as a high-capacity, stable anode material for Li-ion batteries

LiZnVO4 as a high-capacity, stable anode material for Li-ion batteries 4 August 2012 Researchers at Fuzhou University, China, have developed a LiZnVO4 material for use as a high-capacity anode material for Li-ion batteries. Testing found a large capacity of 330 mAh g−1 can be retained after 70 cycles. In a paper on their work published in the journal Ionics , they reported that the LiZnVO4 exhibits excellent cycling stability even at a high current density. ...most of the commercial LIBs [lithium-ion batteries] use graphite as anode material for its excellent cycling behavior. However, low theoretical capacity and poor cycling behavior for graphite anode at a high current density limit its large scale application in high energy-density battery systems. Thus, much attention has been paid to develop new anode materials. Recently, the vanadates have generated a new interest s...
