▎ 摘　　要

NOVELTY - Manufacture of negative electrode material involves synthesizing a graphene structure in a network form by growing the graphene with a catalyst, synthesizing colloidal solution of metal oxide nanoparticles and depositing the metal oxide nanoparticles on the porous graphene structure in the form of a thin film. USE - Manufacture of negative electrode material for lithium secondary battery (all claimed) used in small mobile phones, electric car and smart grid. Uses include but are not limited to electro-chemical catalyst electrode for fuel cell, solar energy conversion photocatalyst, dye-sensitive solar cell and electro-chemical gas sensor. ADVANTAGE - The method produces the electrode with excellent cycle life and fast charging and discharging property (due to the presence of porous graphene and metal oxide nanoparticles). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for negative electrode.
