Influence of detection connection resistance value on cycle performance of lithium battery
The laboratory studies the cycle performance of lithium batteries through charging and discharging cycles,and analyzes the rationality of its material system according to the cycle life curve and data.The reasons for its cycle diving failure are often attributed to factors such as the mismatch of its material system,unreasonable electrolyte,and manufacturing process defects.It is found that the connection resistance between the charging and discharging cabinet and the battery has a great influence on the cycle performance,and the unreasonable connection resistance is easy to lead to abnormal cycle life and battery temperature rise.When the connection resistance value is lower than 0.1 mΩ,the cycle life is normal,and there is no abnormal temperature rise.
