▎ 摘　　要

NOVELTY - Microspheres comprises coral-shaped porous yolk having interconnected mesopores produced by decomposition of thermally decomposable polymer particles having a diameter of 5-200 nm. A shell surrounding the porous yolk and an empty space formed between the porous yolk and the shell, where porous yolk and shell are nickel oxide and carbon composites. USE - Used as microspheres. ADVANTAGE - The microspheres shortens the ion diffusion path that facilitates the penetration of the electrolyte into the yolk during the cycle, very stable SEI layer can be formed on the surface since the yolk-shell structured carbon composite can expand freely; can exhibit ion storage characteristics, has an ideal structure and long-term cycling and speed performance, can accommodate volume expansion induced by repetitive insertion/desorption of Li+ ions and high cycling; can exhibit excellent rate-limiting performance, has highest reversible capacity at high current density and long-term cycling performance compared to other transition metal oxide materials and various previously known carbon hybrids. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram illustrating a microsphere and method for manufacturing the same.
