Assess the Importance of  Lithium Battery Swelling

Lithium-ion battery, as a popular energy storage carrier, has been widely used in life. With the increase of application scenarios, the battery safety also has higher requirements.ln the process of lithium-ion battery charge and discharge, it will be accompanied by different degrees of expansion.

On the one hand, it will affect the deformation of the battery assembly space, on the other hand, the irreversible expansion accumulation will also cause the structural destruction of the active material, thus accelerating the capacity attenuation.In the monomer cell layer, the characterization of cell expansion has more characterization methods.Such as by applying a certain pressure on the cell surface to test the thickness of the cell, the expansion force, the expansion of the cell, including multiple layers of positive and negative electrode, separator, aluminum plastic film oralumi- num shell, cannot accurately locate the source of expansion and quantification of a material. 

So for lithium researchers still have certain limitations.Coin battery is a kind of battery used by lithium researchers, it is composed of a single layer of positive and negative electrode and separator, but due to the binding of the positive and negative electrode steel shell, the electrode of the expansion cannot be measured.If the influence of positive and negative electrode steel shell is excluded and the model coin battery is used to explore the expansion behavior of single layer battery, it can more directly analyze the expansion performance of active material, which is helpful to evaluate the feasibility of material modification and process formula optimization.
