▎ 摘　　要

NOVELTY - The electrode piece has a current collector (1) connected with a continuous negative electrode active substance (2). The negative electrode active substance comprises negative electrode main material, conductive agent and agglomerant. The negative electrode main material comprises artificial graphite, natural graphite or silicon-containing material. An adhesive comprises rubber, polytetrafluoro and ester polymer. The conductive agent comprises carbon nano tube, graphene or carbon powder. USE - Lithium-ion battery negative electrode piece. ADVANTAGE - The active substance is adhered, so that the lithium-ion migration is not blocked by the current collector, so as to effectively improve the battery energy density, improve the safety and reduce the battery cost. The electrode piece ensures simple condition, simple process, and wide application range, and uses the various type of the selected current collector to effectively control the metal dust type and improve controllability. The electrode piece needs less current collecting body amount, which can effectively reduce the raw material cost and effectively improve the battery volume energy density. The electrode piece controls electrode internal current distribution, improves the flexibility, and effectively connects the negative electrode active substance without a current collector barrier. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium-ion battery negative electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a lithium ion battery negative electrode piece. 1Current collector 2Continuous negative electrode active substance 3Mold
