A High Energy Density Li-ion Battery with Lithium Titanium Oxide Anode

To solve the problems of climate change and pave the way towards a more sustainable future, research is being carried out to develop new electrode materials for high-performance batteries. Great efforts are underway to find new materials that can fulfil the demanding requirements for new batteries. Transition metals are a class of materials that are being considered as new electrode materials for rechargeable Li-ion batteries. Such metal oxide structures are attractive due to their high energy density. Lithium titanium oxide is reported here as an electrode for Li-ion batteries having a high energy density and stable structure. Titanium has a low density and high strength which make it a perfect candidate to be used as an electrode for future high energy density. Furthermore, the felt design of the reported titanium also improves the reverse capability of Li-ion batteries. Lithium titanium oxide had a specific capacity of 253.6 mAh/g and retained an excellent 90% of its capacity over 100 cycles. The performance is compared with widely used LiMnO₂ chemistry, against which Lithium titanium oxide performed better in almost all the fields.
