Reducing Diffusion-Induced Stress of Bilayer Electrode System by Introducing Pre-Strain in Lithium-Ion Battery

Lithium-ion battery (LIB), as energy storage devices, is widely used in portable electronic devices and have promising applications in electric vehicles. The volume change and large stress can lead to electrode pulverization and the resultant loss of electrical contact from the current collector, which is considered to be one of the main reasons for the capacity degradation of LIB. To reduce diffusion-induced stress of the electrode system...
