Abstract
With the increasing demand of the consistency on li-ion batteries, to be more stable and consistency for the holding force upon the battery’s charging by the electrode tab-clamps during the battery forming process becomes the basic requirements. This paper offers a new method to test the holding force of a spring clips by using a membrane-type force-sensitive resistive sensor as sensing element. According to the experiment and analysises, this paper also shows the linear fitting on the Pressure-Resistance Characteristic Curve of the sensor, which is close to the actual situation, and provides a basis for the follow-up data processing of the testing system. Multi-groups analysis of experimental data indicates that it is a simple and feasible method to test the holding force of the spring clips using in li-ion battery charging and discharging.
