无负极锂金属电池的存储性能
Storage performance of anode-free lithium metal batteries
摘要
Abstract
Cu||NCM712 pouch batteries were fabricated as the research model.Combined with SEM,XRD,cryo-TEM and charge-discharge tests,the irreversible capacity loss and the reversible capacity loss during the storage process of anode-free lithium metal batteries(AF-LMBs)were evaluated qualitatively and quantitatively.The results show that the initial charging state has no significant effect on the storage performance(capacity retention rate and capacity recovery rate)of the Cu||NCM712 battery at 25℃,and the increase of storage temperature will aggravate the self discharge of the fully charged battery,resulting in an increase of the reversible capacity loss of the battery.Meanwhile,compared with the chemical corrosion between lithium metal and electrolyte,the galvanic corrosion between lithium metal and Cu collector is the main factor causing irreversible capacity loss of Cu||NCM712 battery.关键词
