The abundant Li-storage sites and mixed high electronic and ionic conductivities grant such freestanding C-Ni composite electrode material large reversible capacity and high-rate capability through thousands of cycles even at a great thickness and using no extra current collector.

By developing a simple nickel nitrate-based hard-template preparation, this study demonstrates the smart design of nanocrystalline C-Ni hybrid monoliths with three-dimensionally ordered macroporous (3DOM) frameworks for high-efficiency EES.

Here operando observations are reported of SEI formation, growth, and failure at a high current density by utilizing a mass‐sensitive Cs‐corrected scanning transmission electron microscopy.
