The application requirements for electric tools or household appliances require that the battery cell must meet the requirements of adapting to extreme high and low temperature environments, strong vibration, fast charging and discharging, and the protection design is extremely simple, also possessing high technical requirements. Similar to the high, precision, and cutting-edge technology of automotive power batteries, applications such as electric tools or household appliances require battery cells to possess high technical attributes. Close proximity to the human body and unprotected use conditions all mean relying on the high-performance and high safety support of the battery cell itself.

Compared to other fields, foreign power tool giants have a longer certification cycle for lithium batteries, and have higher requirements for cell discharge rate, capacity, safety, cycle life, and stable supply. This is also one of the reasons why few domestic enterprises have entered the international industry chain. At present, the main manufacturers of batteries for electric tools are several international giants such as Samsung SDI, LG Chemical, Murata, and Panasonic. Among them, Samsung SDI has the highest market share, accounting for over 40%, LG Chemical accounts for about 16-17%, and Murata accounts for about 12-13%.

With the improvement of product quality and technology, as well as competitive prices among domestic enterprises, more and more enterprises are entering the core supplier list of electric tools. With breakthroughs in technology and product quality, there is no significant difference in overall performance compared to foreign enterprises. Electric tools require high discharge rate and current, as well as good vibration resistance. The process requirements are relatively high. Currently, domestic enterprises continue to make breakthroughs in cell rate, capacity, safety, cycle life, and stability, and their products have successively obtained technical certification and recognition from international customers; With recognized technology and good cost-effectiveness, we can enter the supply chain of major foreign customers and gain some share from foreign manufacturers. In addition, the rapid development of the electric vehicle industry has driven an explosion in demand for cylindrical batteries. Companies such as Panasonic and LG Chemical have tilted their cylindrical production capacity or lines towards vehicle manufacturers (Tesla), while the global demand for cordless electric tool batteries is growing rapidly, allowing domestic enterprises to seize this opportunity. However, this year, due to the impact of novel coronavirus pneumonia, Japanese and Korean battery manufacturers were short of capacity, resulting in tight supply in the cylindrical ternary lithium ion battery market. However, domestic production resumed earlier, and the capacity was able to make up for the related gap.
