Cylindrical battery volume expansion in situ test system

System overview:

The cylindrical battery volume expansion in-situ test system provides accurate and real-time data support for developers by in-situ monitoring the volume change of cylindrical batteries during charging and discharging. The system can simulate the charge and discharge cycle of the battery in actual use, and monitor the volume expansion of the battery in real time, which is helpful to optimize the battery design and improve the performance and safety of the battery.

How it works:

The operating principle of the system is based on optical, mechanical or physical measurement techniques to evaluate the volume expansion behavior of the battery by monitoring the morphologic changes on the surface of the battery or the internal pressure changes in real time. Optical imaging technology is a common method, which uses a high-resolution camera or optical sensor to image the surface of the battery in real time, and calculates the volume change of the battery through image processing algorithm.

Core functions:

In-situ monitoring: The system can realize in-situ monitoring of cylindrical batteries during charging and discharging without disassembling the batteries or destroying their structures.

High-precision measurement: The system uses high-precision sensors and measurement technology to accurately measure the volume change of the battery.

Multi-channel testing: Some systems support multi-channel simultaneous testing, which improves the test efficiency.

Data synchronization record; The system can synchronously record the charge and discharge data and volume change data of the battery, which is convenient for subsequent analysis and processing

Real-time 3D reconstruction: Some advanced systems use optical imaging technology to perform real-time 3D reconstruction of the battery surface to more intuitively display the volume expansion of the battery.

Application example:

Taking the CCS1300-4 in situ expansion test system of CCS1300-4 Cinnamon battery of Yuanneng Technology （Xiamen） Co., Ltd. as an example, the system has been successfully applied to the volume expansion test of many kinds of cylindrical batteries. By comparing the volume expansion behavior of cylindrical batteries with different negative electrode materials in the formation and charging and discharging process, researchers can deeply understand the impact of negative electrode materials on battery volume expansion, and provide data support for optimizing battery design and improving battery performance.

Technical features and advantages:

Non-destructive testing: In-situ testing avoids the error and cost of removing the battery or destroying its structure.

High precision and real-time: The system uses high-precision sensors and real-time monitoring technology to ensure the accuracy and real-time test results.

Multi-channel test capability: improves test efficiency and reduces test cost.

Intuitive data display: Some systems can reconstruct the surface topography of the battery in real time, and display the volume expansion of the battery more intuitively.
