AI Technical Summary
Current semi-solid secondary batteries face challenges in achieving high flexibility for electrode active material layers, leading to issues such as cracking and impaired adhesion during charging and discharging, which affect battery resistance and output characteristics.
A slurry for forming electrodes in nonaqueous electrolyte secondary batteries is developed, containing an electrode active material, a conductive aid, a nonaqueous electrolyte, and a resin binder with controlled solubility, allowing for improved binding properties and flexibility.
The proposed slurry effectively enhances the flexibility of electrode active material layers, suppresses deformation during charge and discharge cycles, and maintains excellent bending resistance, thereby improving the overall performance and longevity of nonaqueous electrolyte secondary batteries.
