AI Technical Summary
During the manufacturing process of all-solid-state batteries, solid electrolytes do not easily penetrate into the pores of the electrode active layer, making it difficult for the electrode active material to physically contact the solid electrolyte, affecting the battery performance.
By adjusting the size ratio of the positive electrode active material particles to the solid electrolyte particles, dense and uniformly arranged positive electrode particles are prepared to ensure that the average size of the solid electrolyte particles is within the range of 10% to 20% of the average size of the positive electrode active material particles.
The performance of the positive electrode particles is improved, the adhesion and uniformity of the electrode are enhanced, thereby improving the overall performance of the all-solid state battery.
