Stabilization of planar tetracoordinate silicon (ptSi) was achieved in a 2D-layered extended system, and the newly designed ptSi SiC8 siligraphene shows novel structural and electron-storage features.
Hierarchically structured and ammonium-rich Prussian blue analogue materials are prepared by a one-step hydrothermal method, and show excellent lithium storage performance.
N, S co-doped carbon coated MnOS (MnOS@NSC) has been demonstrated to be a potential anode material for LIBs with high capacity, good cycling stability and excellent rate performance.
