▎ 摘　　要

NOVELTY - The electrode (22) has a first electroactive material comprising siliceous particles having an average particle diameter of about 1 mu m. An electroconductive material contains graphene nanoplates. A polymeric binder comprises a polyimide, a polyamide, polyacrylonitrile, polyacrylic acid, a salt of polyacrylic acid, polyacrylamide, polyvinyl alcohol, carboxymethyl cellulose, or a combination of polyimide, a polyamide, polyacrylonitrile, polyacrylic acid, a salt of polyacrylic acid, polyacrylamide, polyvinyl alcohol, and carboxymethyl cellulose. The first electroactive material is present in the negative electrode in an amount of from about 60% to about 95% by weight based on the total weight of the negative electrode. USE - Negative electrode for electrochemical cell (claimed) such as lithium-ion battery used for small or large scale processes used in vehicle such in hybrid electric vehicles (HEVs) and electric vehicles (EVs) or car transport applications such as motorcycles, boats, tractors, buses, motorcycles, mobile homes, caravans and tanks. Uses but are not limited to other industries and applications, e.g. in aerospace components, in consumer goods, appliances, buildings such as houses, offices, sheds and warehouses, office equipment and furniture and in machines for industry, in agricultural or agricultural equipment or in heavy machinery and power consuming load devices, such as an electric motor for a hybrid or purely electric vehicle, laptop computer, tablet-computer, cell phone and cordless power tools or appliances, case, gaskets, terminal caps, tabs, and battery terminals. ADVANTAGE - The cells with the graphene nanoplates in the negative electrode are very stable and reproducible. The methods are useful for maximizing the specific power and energy density of electrochemical cells, such as lithium-ion batteries. The first heat treatment advantageously results in a negative electrode with a robust mechanical and electrical network capable of overcoming the challenges. The use of graphene nanoplates results in a slurry with improved flow properties, which achieves improved slurry uniformity and dispersion. The graphene nanosheets advantageously act as flow modifiers due to their layered plate structure. The inclusion of graphene nanoplates advantageously lowers the viscosity of the slurry and allow for a higher total solids content of the slurry, which has the beneficial effect of using less solvent in the formulation, which improves the overall processability of the slurry, i.e. mixing and coating the slurry. The shaped electrode has fewer aggregates and has a more homogeneous conductive network and a more even current distribution. The negative electrodes are provided with a robust mechanical and electrical network.
