New energy lithium battery cover plate

Abstract

The invention relates to the technical field of new energy lithium battery production, in particular to a new energy lithium battery cover plate. The new energy lithium battery cover plate comprises acover plate; a base surface of the cover plate is provided with through holes; the bottom of the cover plate is provided with grooves; springs are disposed inside the grooves; the inner walls of thethrough holes are provided with pinch plates; the pinch plates are fixedly connected with baffle plates; the pinch plates are connected with a lithium battery; the cover plate comprises a first layerplate; the bottom of the first layer plate is covered with open fiber cloth A; the bottom of the open fiber cloth A is connected with a second layer plate; the bottom of the second layer plate is covered with open fiber cloth B; the bottom of the open fiber cloth B is connected with a bottom layer plate; and the interior of the cover plate is vertically connected with glass fibers. According to the invention, the glass fibers pass through the first layer plate, the second layer plate and the bottom layer plate, the bottom of the open fiber cloth A is connected with the second layer plate, andthe bottom of the second layer is covered with the open fiber cloth B, so that the strength and toughness of the cover plate are increased; the cover plate is endowed with explosion-proof properties and is extremely safe to use; by locating the lithium battery on the base surface of the cover plate, complicated assembly is reduced; and the cover plate is extremely simple in structure, thereby saving assembly time.

Description

technical field [0001] The invention relates to the technical field of production of new energy lithium battery equipment, in particular to a new energy lithium battery cover plate. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the widespread use of digital products such as mobile phones and notebook computers, lithium-ion batteries have been widely used in such products due to their excellent performance, and are gradually developing into other pro...
