Heating method of polymer lithium ion battery high-temperature fixture formation equipment

Abstract

A heating method of polymer lithium ion battery high-temperature fixture formation equipment comprises the following steps: casting reticulation electrothermal tubes or reticulation stainless steel tubes respectively under pressure in two aluminum heating plates; electrifying the reticulation electrothermal tubes or injecting circulating hot water into the reticulation stainless steel tubes, so as to heat the aluminum heating plates, and further charging a polymer lithium ion battery tightly clamped between the aluminum heating plates when the battery is being heated. Therefore, the reticulation electrothermal tubes or the reticulation stainless steel tubes are cast into the aluminum heating plates under pressure through heating of aluminum ingots for melting, pressure casting and integral formation; when the reticulation electrothermal tubes are electrified or circulating hot water is injected into the reticulation stainless steel tubes, the aluminum heating plates are heated, and both surfaces of each aluminum heating plate radiate heat uniformly, so that the upper and lower aluminum heating plates can be used for charging the polymer lithium ion battery tightly clamped between the aluminum heating plates when the polymer lithium ion battery is in a heated state, both sides of the battery are heated uniformly, temperature rise is fast, the capacity of a formed battery plays a role sufficiently, and the battery is thinner, even in surface, and beautiful.

Description

technical field [0001] The invention relates to the technical field of formation of lithium batteries, in particular to a heating method for high-temperature fixture formation equipment of polymer lithium-ion batteries. Background technique [0002] At present, in the prior art, the heating part of the high-temperature formation equipment for polymer lithium-ion batteries uses hot air radiation, but its heating efficiency is low and energy consumption is high; Low, long-term pressure is easy to age and damage, short life, and because of the low hardness of the silicone heating part, the surface of the polymer lithium-ion battery produced by its formation is not smooth enough, which affects the appearance. [0003] In view of this, it is necessary to provide a heating method for high-temperature fixture formation equipment that can improve heating efficiency and reduce energy consumption, a heating plate that is not easily damaged, and a polymer lithium-ion battery product pr...
