Abstract :
[en] Batteries have become essential in tackling global warming and energy security. Rechargeable Li-ion technology (LIBs), by having the highest energy density of any such device, is mainly dominating in the fields of consumer electronics and electric vehicles. Given the high demand and fast-growing market, Li-ion batteries cannot stand alone to fulfill all future needs. This has boosted the exploration and discovery of novel electrochemical energy conversion and storage technologies based on more abundant, cheap, and accessible materials with the lowest environmental impact. Therefore, it is urgent to develop new sustainable and affordable energy storage devices with high safety, lower cost, and high energy density to realize mobiles and large-scale applications. As alternatives, battery chemistries based on more abundant elements (e.g., Na, K, Zn) have received extensive attention (1-5). Different approaches to boost the practical energy density and cycle life of electrode materials for next-generation rechargeable batteries will be presented. The optimization of the synthesis of different active electrode materials is reported. Different strategies are used to further stabilize and boost the electrochemical performance. References:
