AI Technical Summary
When increasing the thickness of existing battery electrode materials to improve energy density, the conductivity decreases, resulting in the ineffective utilization of some active materials. Furthermore, high-capacity materials may damage the battery during volume changes, reducing energy density and performance.
By introducing a compositional gradient into the electrode material, the physical, chemical, and electrochemical properties of the material are adjusted along the electrode thickness direction, including changing the porosity, active material concentration, and conductive material distribution, to improve the conductivity and stability of the electrode.
It achieves higher energy density and better battery performance, avoids battery damage caused by material expansion and contraction, and improves the conductivity and stability of the electrodes.
