At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles. Therefore, the inherent particle properties of electrode materials play the decisive roles in influencing the electrochemical performance of batteries.
This article explores the primary raw materials used in the production of different types of batteries, focusing on lithium-ion, lead-acid, nickel-metal hydride, and solid-state batteries. 1. Lithium-Ion Batteries
The stability and loss rate of positive electrode materials directly affect the cycle life of lithium batteries. During the charging and discharging process, the loss of active substances in positive electrode materials and the destruction of material structure will lead to the attenuation of battery performance.
The development of excellent electrode particles is of great significance in the commercialization of next-generation batteries. The ideal electrode particles should balance raw material reserves, electrochemical performance, price and environmental protection.
The ideal electrochemical performance of batteries is highly dependent on the development and modification of anode and cathode materials. At the microscopic scale, electrode materials are composed of nano-scale or micron-scale particles.
