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

Abstract

<p>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. By using lithium titanium oxide we can produce batteries having energy density well above 1000 Wh/l</p>
