固态锂电池在载运工具中的应用前景分析

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.
