Battery Cell Reinforcing Material with Ceramic Polymer Gel

The patent applies composite materials by combining ceramic particles (such as Al2O3, SiO2, TiO2) with polymer gel to create a reinforcing material that provides both mechanical strength and flexibility. This composite structure enables the battery cell to achieve high bending rigidity while maintaining a relatively simple overall design, as the composite material itself provides multiple functions (reinforcement, protection, and structural integrity) in a single integrated component.

The reinforcing material serves multiple functions simultaneously: it provides mechanical reinforcement to prevent deformation, protects the electrode assembly from damage, maintains structural integrity under thermal stress, and prevents internal short circuits. By integrating these multiple functions into a single component, the patent achieves high reliability without significantly increasing manufacturing complexity, as the multi-functional material can be applied in a straightforward manufacturing process.

The patent utilizes the unique thermal properties of ceramic materials (such as Al2O3, SiO2, TiO2) to maintain structural stability at high temperatures. The ceramic particles are dispersed within the polymer gel matrix, creating a composite that can withstand thermal expansion and contraction without deforming. This approach provides excellent temperature resistance and reliability, while the straightforward dispersion method keeps manufacturing processes relatively simple.
