Description

technical field

[0001] The invention belongs to the field of fluid metering equipment, and in particular relates to a high-efficiency liquid injection pump device used in the production of lithium-ion batteries. Background technique

[0002] Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries.

[0003] Lithium-based batteries are divided into lithium batteries and lithium-ion batt...
