Filling syringe for battery and battery injector therewith

Abstract

This is a cell needle and the injection device. The needle is of an inner cavum which is sealed in a vacuum needle and steel ball matching to the end of the needle. There is a concave part on the side wall of the cavum, and an electromagnet is installed to the position of the concave part.

Description

technical field [0001] The invention relates to battery processing equipment, in particular to a battery liquid injection needle and a battery liquid injection device using the liquid injection needle. Background technique [0002] As a new type of green and environmentally friendly battery, liquid lithium-ion secondary battery represents the advanced level of current chemical power supply development. Due to the advantages of high specific energy, long cycle life, no memory effect, safety and pollution-free, and fast charging and discharging, lithium-ion batteries have been widely used in electronic devices such as cameras and notebook computers, and are gradually being used in electric bicycles and electric vehicles. and other fields to expand the scope of application. [0003] Researchers from various countries have not only conducted a lot of research on the positive and negative electrode materials of the battery, the electrolyte and the structure of the battery, but a...
