Lithium polymer batteries, battery and assembly

Polymer lithium battery is a kind of electrolyte for gel, soft packing lithium battery, often referred to as soft package in the civilian market lithium-ion batteries, which makes lithium-ion battery batteries have different place with ordinary liquid lithium ion battery, thus some special considerations, the following batteries that may occur in the process of use and assembly is not the right approach made the following considerations. One, in the use of batteries, including of aluminum-plastic composite membrane, sealing side, A shaft end sealing side) , side sealing side, extremely handle protection and measures to avoid mechanical impact, short circuit. 1, lu: su composite film packaging protection: the main is to avoid from damage by the sharp parts stabbed. Therefore, we should always clean up battery surroundings, banning sharp collision parts contact or batteries, can put on the gloves when use, avoid fingernails scratch the surface of the batteries. 2, top sealing side and side sealing side protection: to avoid the top sealing side and side sealing side damage, damage to the sealing effect, should be prohibited from bending top sealing side and side sealing side; At the same time, the batteries to design the insulation of the reliable isolation measures must be taken to avoid the negative and aluminum-plastic composite membrane docking short circuit. 3, handle protection: lithium polymer batteries batteries positive leading-out terminal aluminum handle, the cathode leading-out terminal using nickel handle. Due to the extremely thin, should be prohibited from bending; At the same time, in the process of production should be avoid extremely handle contact with lu: su composite membrane, with strict isolation ring membrane. 4, to avoid mechanical impact, such as the fall, hit, bending batteries and carelessly trampled the battery. 5, it is prohibited to use metal, wire short circuit connected is negative. 2, a batteries well, the next step is to shell and batteries right protection circuit module combination, make it a polymer battery, matters needing attention in the process are: 1, shell design: ( 1) , sufficient mechanical strength to avoid the batteries from external mechanical damage, ( 2) , batteries installed in the shell, shell to avoid the sharp edge scratch batteries; ( 3) Pure aluminum, prevent the aluminum-plastic composite membrane interlayer contact with external and short circuit. 2, must design batteries to protect circuit, including the maximum/minimum voltage set of science, over-current protection, you can use the combination of batteries to the battery unit ( Only batteries) To charge discharge protection. Article 3, the anode aluminum handle by nickel to transfer, and the batteries connected to the circuit board of the ultrasonic welding and spot welding technology should be adopted to implement. 4, reliable positioning of batteries, batteries assembled in the shell should be tighten, not activities, make the whole structure of lithium battery in a state of consolidation.
