Abstract

The invention provides a soft-packing battery high vacuum micro-channel water removing device. The soft-packing battery high vacuum micro-channel water removing device comprises a rack. A high vacuumcavity, a thermal fluid tank and a cool fluid tank are arranged in the rack. Micro-channel flat pipes and flow collecting pipes are arranged inside the high vacuum cavity. Multiple micro-channel flatpipes spaced up and down are arranged between two flow collecting pipes, and the flow collecting pies communicate with the micro-channel flat pipes. The thermal fluid tank and the cool fluid tank communicate with the two flow collecting pipes in a circulating manner through a water pump, a valve, a pipeline. According to the soft-packing battery high vacuum micro-channel water removing device, when a vacuum pump works, gas inside the high vacuum cavity is brought out; and meanwhile, water is taken away, and a water removing part is played. Energy is supplemented for soft-packing battery volatile gas by a heating device in the high vacuum cavity of the device, thermal efficiency is high, energy consumption is low, and the temperature is consistent. After water removal is finished, the thermal liquid tank is switched as the cool liquid tank, the battery is cooled in a vacuum environment, and moisture regain of water vapor generated by evaporating the battery is prevented.

Description

technical field

[0001] The invention relates to the technical field of lithium-ion battery production, in particular to a high-vacuum micro-channel water removal device for soft-pack batteries. Background technique

[0002] During the production process of pouch batteries, it is necessary to dewater the pouch batteries to control the water content of the pouch batteries. The traditional water removal method is as follows: place the pouch battery in the heating chamber, and the heating element sends hot air into the heating chamber to heat and remove water; then transfer the pouch battery to the cooling chamber, and replace the gaseous water with nitrogen or dry gas And take it away, and at the same time realize the cooling of the pouch battery; in the above process, the sensor senses the temperature of the heating chamber, and then feeds it back to the heating element, and controls the temperature by turning on and off the heating element or reducing the voltage.
