Abstract
A strain-alleviating strategy was developed by creating a layered-spinel alternate heterostructure for LROs, resulting in a 3D channel for lithium-ion diffusion which was capable of reducing structural strain during the intercalation/deintercalation of Li + , thereby enhancing dynamic stability.
