3D digital twin identifies causes of battery degradation during fast charging

Fast-charging electric vehicles damages batteries internally, but a KAIST research team has built a 3D digital twin to identify exactly why. By simulating a real commercial graphite anode, they discovered that how binder materials and pore spaces are arranged inside electrodes matters as much as how much is used. Strategic binder placement boosted charge capacity by 18% in thicker anodes, helping manufacturers design longer-lasting EV batteries without costly physical trial-and-error testing.
