Ultrathick electrode design is a promising strategy to enhance the specific energy of Li‐ion batteries (LIBs) without changing the underlying materials chemistry. However, the low Li‐ion conductivity caused by ultralong Li‐ion transport pathway in traditional random microstructured electrode heavily...
