Battery Material for Lithium-Ion Battery


Abstract/Technology Overview

A novel lithiated tin vanadium oxide (LSVO) compound has been synthesized via straight-forward, simple, economical and scalable sol-gel method. Interpretation and indexing softwares have been used to predict the crystal structure system to be tetragonal. A preliminary test on Li-ion half cell with the configuration LSVO//Li using 1 M lithium hexafluorophosphate (LiPF6) in EC:DEC (v/v = ½) as electrolyte has shown reversible capacity of 211 mAh g-1 at the end of 53rd cycle when discharged at 1 V. The discovery of this novel material is at its infancy and the detailed methodology of this novel compound synthesis has been filed for patent.


Technology Features, Specifications and Advantages

It is well-known that lithium-ion batteries (LIBs) has become an essential energy storage device in modern life style. However, the multiple incidents of battery explosion have once again question the safety of LIBs, leading to a massive recall of smart phones in 2016. The formation of lithium dendrites at graphite anode during high rate charging might cause short-circuit and give rise to serious thermal runaway. Lithium cobalt oxide cathode, on the other hand, is expensive and toxic. In this work, we will demonstrate a potential substitute of electrode material for LIB. A novel lithiated tin vanadium oxide (LSVO) compound has been synthesized via straight-forward, simple, economical and scalable sol-gel method. The battery employing this new electrode material has been tested on small devices and electronic components such as calculator, watch and others.


Potential Applications

The battery employing this new electrode material has been tested on small devices and electronic components such as calculator, watch and others. This technology has higher specific capacity than graphite as anode materials, non-toxic and eco-friendly, long technological lifespan as it can last long as long as it is well-kept under moisture free condition, low cost material.
