摘要:

目前,新能源汽车的动力电池类型以液态锂离子电池为主,而液态锂离子电池内部的电解液存在易泄漏、可燃和易爆问题。固态锂电池因采用锂金属作为负极材料而具备高能量密度,且将可燃易爆的液体电解质替换为不易燃不易爆的固体电解质,在新能源汽车及其他载运工具中具有广阔的应用前景。对包含铅酸电池、镍系电池及目前应用较多的锂离子电池在内的二次化学电池研究现状进行了梳理;重点分析了固态锂电池电极与电解质技术。固态锂电池的电解质种类主要有氧化物、硫化物与聚合物三类,从电解质种类的角度梳理了固态锂电池的相关技术发展水平及产业化进展;最后对各种载运工具的特点进行总结,并对未来固态锂电池在各种载运工具中的应用前景进行了合理分析。

Abstract:

Currently, liquid lithium-ion batteries are the most common type of power battery used in new energy vehicles, however, liquid lithium-ion batteries have the problems that electrolyte is prone to leakage and is flammable and explosive. Due to the use of lithium metal as the negative electrode material, the solid-state lithium batteries have a high energy density, and substitute the flammable and explosive liquid electrolyte with solid electrolyte that is neither flammable nor explosive. For these reasons, the solid-state lithium batteries will have wide range application prospects in new energy vehicles and other carriers. The research status of secondary chemical batteries is reviewed, including lead-acid batteries, nickel-based batteries and lithium-ion batteries that are currently widely used. The electrode and electrolyte technology of solid-state lithium-ion batteries are emphatically analyzed. The main electrolyte types of solid-state lithium batteries are oxides, sulfides and polymers. From the perspective of electrolyte types, the relevant technical development level and industrialization progress of solid-state lithium batteries are analyzed. Finally, the characteristics of various carriers are summarized and the application prospects of solid-state lithium batteries in various carriers are reasonably analyzed.

Key words: Solid-state lithium batteries, power battery, space power supply, solid electrolyte, application prospects
