Özet

Sustaining a sound structure in Si-based anodes is extremely challenging because of the high volumetric expansion that occurs upon cycling. To maintain capacity retention during the cycling, there is a need for new designs that rely on engineering-specific hierarchical geometries and/or optimized composite compositions such that at least one of the multiple elements serves as buffer and/or electron conductive pathway in the electrodes. Here, we report an innovative design in which alternate layers of atomic structures involving multiple elements form a new anode material for lithium-ion batteries.
