The development and application of lithium-ion batteries present a dual global prospect of opportunity and challenge. With conventional energy sources facing reserve shortages and environmental issues, lithium-ion batteries have emerged as a transformative technology over the past decade, owing to their superior properties. They are poised for exponential growth in the realms of electric vehicles and energy storage. The cathode, a vital component of lithium-ion batteries, undergoes chemical and electrochemical reactions at its surface that directly impact the battery's energy density, lifespan, power output, and safety. Despite the increasing energy density of lithium-ion batteries, their cathodes commonly encounter surface-side reactions with the electrolyte and exhibit low conductivity, which hinder their utility in high-power and energy-storage applications. Surface engineering has emerged as a compelling strategy to address these challenges. This paper meticulously examines the principles and progress of surface engineering for cathode materials, providing insights into its potential advancements and charting its development trajectory for practical implementation.
锂离子电池的发展与应用呈现出机遇与挑战并存的全球双重前景。随着传统能源面临储量短缺和环境问题，锂离子电池凭借其卓越性能在过去十年中成为一项变革性技术。它们在电动汽车和储能领域有望实现指数级增长。阴极作为锂离子电池的关键组件，在其表面发生的化学和电化学反应直接影响电池的能量密度、寿命、功率输出和安全性。尽管锂离子电池的能量密度不断提高，但其阴极通常会与电解质发生表面侧反应，且导电性较低，这阻碍了它们在高功率和储能应用中的效用。表面工程已成为应对这些挑战的一种引人注目的策略。本文详细探讨了阴极材料表面工程的原理与进展，深入了解其潜在进展，并规划其实际应用的发展轨迹。
