Li-ion batteries have become popular for electric vehicles, smart grids, and electronics due to their high power and energy density as well as long cycle life. The energy density and performance of Li-ion batteries depend greatly on the properties of the cathode and anode materials used. Li-ion batteries offer higher energy density, higher cell voltage, fast recharging, low self-discharge, and can last for tens of thousands of charge/discharge cycles.

- 1. Li-ion battery (LIB) has shown a great potential to fulfil the growing energy demands for hybrid electric vehicle, smart grid applications, and portable electronic devices, due to its advantages such as high power and energy density, long cycle life and structure stability. The energy density and performance of LIBs are largely determined by the chemical and physical properties of the cathode and anode materials. Why lithium ion? • Higher energy density. • Higher cell voltage. • Fast recharge. • Low self discharge. • Life can extend tens of thousands of cycles. Background: Li-ion battery
