SSEs with high mechanical strength, non-flammability, and stable chemical/electrochemical properties are firmly accepted as a component for flexible batteries. 30, 31 For instance, an ultrathin, flexible lithium battery with 8.6-μm-thick nanoporous polyimide/PEO film SSEs exhibits 200 stable cycles at 60°C while withstanding abuse tests such as bending,
The volume strain induced during the battery operation leads to additional compressive forces and changes the tension and bending forces. Due to the appearance of bending stress at the winding radii, impairments of the particulate electrode layer and current collector foil composite can occur.
5.2. SOC effect on the mechanical response of battery cell under three-point bending The authors suggest that the SOC-dependent tensile behaviors of battery components cause a noticeable rise in the force level and bending stiffness of the tested batteries.
Currently, lithium-ion batteries are among the most promising solution for electrical mobility applications, because of their high power densities. 3 However, there are numerous challenges to be overcome in order to reach implementation.
To characterize the adherence of the coating on the substrate under defined bending stress uncalendered and Li (LiMnAl) 2 O 4 cathodes at calendering grades of 15.2 %, 25.0 % and 34.2 % have been examined with a coating thickness of 86 μm, 73 μm, 64 μm and 57 μm.
The industrialized winding of electrode–separator composites (ESCs; “jelly rolls”) applies bending stress to the winding mandrel. This affects the mechanical integrity of the substrate's coating and adhesion and may reduce the cycle stability and the battery life.
Bending stress is correlating with electrical resistance between coating and substrate. That is because in batteries the quality of contact between coating and substrate represents a measure for electron transport. So far, only best practices are used to design winding cores for manufacture of ESCs.
