【摘要】 作为最早实现商业化的锂离子电池正极材料,钴酸锂（LiCoO₂）一直是学术界和产业界关注的重点。目前以LiCoO₂为正极的商用锂离子电池大部分是为小型电子器件进行供能,限制其广泛应用的主要因素是能量密度和安全性能。随着社会的发展,人们在智能电子设备、便携工具和电动汽车等方面的需求越来越高,对提供能量的电池提出了更高的要求。为了实现LiCoO2正极材料的更广泛应用,需要不断优化其性能,同时还需要考虑安全性、稳定性和价格等其他因素。因此,不仅要研究LiCoO₂本征性质,还要从整个电池体系考虑,揭示与其匹配的电解液和电池构造等方面的因素。以更广泛的商业化应用为目的,从LiCoO₂材料本身入手,总结其近几年的研究进展,对LiCoO₂的性能优化进行了着重介绍,并对其未来的发展进行了展望。更多还原

【Abstract】 As the earliest commercialized cathode material for lithium-ion batteries,LiCoO₂ has been the focus of attention for a long time.At present,most commercial Li ion batteries with LiCoO₂ as cathodes supply energy for small electronic devices.The main factors limiting their applications are energy density and safety concern.With the progress of society,people have growing demands for intelligent electronic devices,portable tools,electric vehicles,etc.,which have put forward higher requirements for batteries.In order to realize the application of LiCoO₂ to wider fields,it is necessary to continuously optimize their performance,and at the same time,other factors also need to be considered,such as safety,stability,and price.Therefore,not only the intrinsic properties of LiCoO₂,but also the entire battery system should be considered,especially the electrolyte and battery structure.For the purpose of wider commercial applications,started with LiCoO₂ itself,the research progress was summarized,the performance optimization was mainly introduced,and future development was looking forward.更多还原
