Abstract

The invention discloses a high-speed short circuit testing device for a lithium battery. The high-speed short circuit testing device comprises a base, wherein a movable slot is formed at the middle ofthe top end of the base along the width direction of the base; vertical springs are equidistantly connected in the movable slot along the length direction of the movable slot; the top end of each spring is connected with a movable plate; symmetric sliding blocks are arranged on the two sides of the movable plate respectively; symmetric sliding chutes are arranged in the side walls of the base atthe movable slot respectively; the sliding chute is in slip connection with the sliding block; electrical contacts are connected with other two side walls of the base at the movable slot respectively;two motor mounting slots with the same structure are formed at the top end of the base; the two motor mounting slots are positioned on the two sides of the movable slot and are arranged in skew symmetry. With a novel structure, the device disclosed by the invention can perform fast batch detection on the finished products of lithium battery, and thus increases the test speed, reduces the defective rate of the lithium batteries and improves the production efficiency, being suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of lithium battery detection, in particular to a high-speed short-circuit detection device for lithium batteries. 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 development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batterie...
