To answer the intensive quest for enhanced lithium ion battery equipped to future automobiles and other advanced applications, new generation anode with good storage properties, great safety and low production cost is currently extensively explored.Transition metal oxides are one of the mostly studied candidates, which are able to uptake/release lithium ions through a new operating concept, 'conversion reaction'.However, several factors currently handicap the conversion reaction-based anodes from commercialization.Hence, scientific research and breakthroughs to meet the application requirements are still an imperious need.
