摘要
讨论了锂离子电池所用嵌入式化合物的固体化学问题。在相同的质量和体积下,锂离子电池的能量是普通电池的两倍,它是未来消费电子产品、电动汽车和可移植医疗器具(加人工心脏)发展的关键所在。简要介绍了二次锂电池正极嵌锂化合物的基本原理,嵌入式化合物的结构-性能关系,最后讨论了几种重要的可嵌入正极材料的晶体结构、电子结构和嵌入化学;展望了几种有希望用于新一代充电锂电池的化合物。
The solid-state chemistry of interc alation compounds for a rechargeabl e Li-ion battery were dis-cusse.The battery can store more than twice the energy compared with conventional alternatives of the same size and mass and holds the key to the f uture improvement of consumer electronic products(e.g.laptop computer),electric vehicles and implantable medical devices(e.g.the artificial heart).One of the attentions is focused on those lithium intercalation compounds that are useful as positive electrodes.The basic operation of the cell is briefly summarized and the structure-property relationsh ips are developed.Finally,the crystal structure,electronic structure an d intercalation chemistry of severa l important positive intercalation electrodes are discussed,including some which show considerable promise for applications in future generations of rechargeable Li-ion batteries.
