▎ 摘　　要

NOVELTY - Lithium battery structure (10), comprises: a first metal layer (12) comprising aluminum foil or stainless steel foil; a second metal layer (14) comprising copper foil, nickel foil or stainless steel foil opposite to the first metal layer; a separator (16) disposed between the first metal layer and the second metal layer; a first electrode layer (18) disposed between the first metal layer and the separator; a second electrode layer disposed between the second metal layer and the separator; and a first functional layer comprising a first composition disposed between the first metal layer and the first electrode layer, where the first composition comprises 20-80 pts. wt. flake conductive material, 1-30 pts. wt. spherical conductive material, 10-50 pts. wt. thermoplastic elastomer and 1-25 pts. wt. nitrogen-containing hyperbranched polymer, based on 100 pts. wt. first composition. USE - The structure is useful for lithium batteries are generally used to drive electronic products (e.g. mobile phones, robots, or AR glasses) and electric vehicles. ADVANTAGE - The structure: has functional layer arranged on metal foil (copper or aluminum) can also resist corrosion of electrolyte, avoiding metal foil from being corroded by solvents and oxidizing its own materials; utilizes thermoplastic elastomer that can be used as a binder in functional layer increases, functional layer can also be used as bonding layer to form comprehensive bonding with metal foil, effectively improving bonding strength between electrode active layer and metal foil; provides battery encounters abnormal conditions and temperature rises sharply, for example, the temperature exceeding 150degrees Celsius, the functional layer produces irreversible Z-axis expansion due to alterations of the internal polymer structure, causing chain mechanism of conductive network inside functional layer to be affected or even cut off and destroyed; utilizes slurry was thicker and less uniformly dispersed, the stirring speed was increased to 2000-4000 rpm; and order to improve safety of batteries during operation, and provides with function of over-temperature current blocking. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for lithium battery structure. DESCRIPTION OF DRAWING(S) - The figure shows cross-sectional view of the lithium battery structure.
