Lithium-ion battery has recently become the flagship of mobile storage of electrical energy. After several updates, manufacturers have managed to achieve the optimal combination of capacity, voltage and weight. In this case, there is practically no memory effect, and the existing shortcomings in working in sub-zero temperatures, overcharging or over-discharge are easily eliminated by the use of new chemical compounds such as decanter and the use of modern power balancing boards.

Lithium ion batteries, they can be called a real revolution in the creation of energy-Autonomous systems and devices. All that existed before, this household batteries and costly batteries for radio stations and other professional devices. Lithium-ion batteries have significantly expanded the range of devices that can be transferred to an Autonomous mode of existence. Already today we are talking about vacuum cleaners, mixers, food processors, tomorrow – irons, grills and welding machines. A special place in this list is electric transport. Once it was electric cars on radio and batteries, now it is self-balancing scooters, electric scooters and Segways.

Spot welding of 18650 batteries

This article is for those who have not heard what is spot welding of 18650 batteries. You can't say that as something new. The technology itself has existed for several decades and is widely used in the welding of automobile bodies. With the advent of 18650 battery cells, the problem of assembling them into single battery packs became acute. Here and remember that there is a way to bond metallic elements like spot welding, not warming them and providing a secure bond.

Spot welding 18650

Lithium ion 18650 battery in the battery blocks are held together not by the normal soldering. Spot welding 18650 is carried out on special devices. The principle of operation of such a device is based on the short-term current transmission between the two electrodes and the contact plate. Due to the large value of the transmitted current and the short-term pulse, in places of contact there is a strong point heating. As a result, metals penetrate each other and form a strong connection.
