Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a voltage detection device for processing high-energy-density lithium iron phosphate batteries. Background Art

[0002] High-energy-density lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material. Its working principle is to realize the charging and discharging process through the migration and embedding reaction of lithium ions. During charging, lithium ions are released from the lithium iron phosphate positive electrode and transferred to the negative electrode through the electrolyte. During discharge, lithium ions are released from the negative electrode and re-embedded into the positive electrode. This reversible lithium ion migration and embedding reaction enables lithium iron phosphate batteries to achieve high energy density, long cycle life and excellent safety performance.

Voltage testing can help identify the voltage differences of individual cells in the battery pack, thereby ensuring the stability and safety of the overall performance of the battery pack.
