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 has once again question the safety of LIBs, leading to a massive recall of smartphones 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 etc.
