Abstract
The modern society dictates the high demand for advanced energy storage systems with high capacity and durability. Therefore, the development of the next generation Li-ion batteries (LIBs), which meets the power and energy requirements for new applications, demands the introduction of innovative anode materials. Silicon has the highest possible capacity of 4200 mAh g-1 among all commonly used anodes [1]. However, its main drawback is mechanical degradation upon cycling due to a huge volume expansion up to 400% during lithiation process [2]. Due to its ‘zero-strain’ (<1% volume change) properties and stable cycling, Li4Ti5O12 (LTO) is considered as a promising anode for LIBs. However, LTO has low capacity. Combination of these two anode materials is considered as a promising approach to prepare a high performance composite cathode.
