A Robust Bundled and Wrapped Structure Design of Ultrastable Silicon Anodes for Antiaging Lithium-Ion Batteries

Silicon with its high theoretical specific capacity for Li-ion storage has long suffered from its huge volume expansion and low intrinsic electronic properties, leading to poor rate performance and cycling stability. Recently, considerable efforts have been placed on achieving increased cycle life using nanomaterial structuring approaches. However, finding an efficient strategy to realize high capacity with a long cycle life of Si anodes is …
