Lithium-ion Battery Battery Gassing Volume Tester

Why Use IEST GVM 2200

1.The formation process of lithium-ion batteries will generate a large amount of gas. The volume of gas produced is closely related to the chemical system of the battery. The formation conditions determine the formation quality and formation time.

2. Overcharging of lithium-ion batteries will cause obvious gas production, which will cause a sudden increase in battery volume or pressure, and increase the risk of thermal runaway of the battery. It is often necessary to monitor the production for early warning at the initial stage of overcharging.

3. Lithium-ion batteries will also produce gas during long-term storage or circulation, especially under high temperature conditions. Therefore, it is necessary to monitor the cycle of gas production in a certain period to evaluate the reliability of the battery.

4.IEST GVM 2200 adopts high-precision mechanical monitoring system to record the volume change of the battery in the whole charging and discharging process in real time in order to obtain the accurate gas production volume and gas production rate of the battery cell at each stage. Thereby improving research and development efficiency and reducing production costs.
