The trend of cordless power tools will greatly enhance the installed capacity of lithium batteries, power tools are a mechanized tool with electric motor as the power to drive the work head through the transmission mechanism, according to the source of electricity can be divided into two types of corded power tools and cordless (rechargeable class) power tools. At present, the vast majority of cordless (rechargeable class) are using lithium batteries as power storage.
Specific classification of power tool products
Power tools increased dramatically in popularity in the 1940s and have now become indispensable tools and equipment in industrial and family life in developed countries.
China's power tools have been mass-produced since the 1970s. For more than half a century, the scale of China's power tool market has been growing in the process of taking over the international division of labor and replacing the status of hand tools.
In the process of popularization of power tools, more and more home consumers tend to do their own small tasks, cordless, portability, small and light become the current product development trend of power tools. The trend of cordlessness will give a broad market space for lithium batteries for power tools.
In addition, lithium batteries instead of nickel-cadmium batteries to accelerate, will also give rise to a large number of market replacement space. Compared with nickel-cadmium batteries, lithium batteries are less polluting to the environment, large power reserves, light weight, long life, short charging time, in line with the trend of miniaturization and light weight of power tools. 2017, the European Union has legislation to force the withdrawal of nickel-cadmium batteries for power tools, the domestic also accelerate the construction of lithium battery specification system for power tools, the full popularization of lithium batteries in the power tool market will bring huge demand for lithium batteries.
From the domestic point of view, the past five years, although China's power tools lithium level continues to improve, but as of the end of 2019 only reached 23%, lithium tool production reached 0.6 billion units, compared to the total scale of 260 million units of power tools still has a lot of space for replacement.
In 2019 Shenzhen Ruiding Electronics Co., Ltd. in the lithium battery for power tools re-layout, expand the ability to respond to the lithium battery for power tools project. And successfully developed an integrated control control function of the battery power management system.
With the accelerated popularity of lithium for power tools, future expansion and investment events for lithium batteries for power tools will be more frequent. ggii predicts that the lithium rate of domestic power tools will rise from 23% in 2019 to 55% in 2023, and the production will reach 151 million units, which will give rise to a lithium battery demand scale of 7.5GWh.
The performance requirements of lithium batteries for power tools are mainly focused on two major aspects: 1) high multiplicity; 2) high consistency.
Future batteries for power tools will show the following trends.
1) Cordless power tools to occupy the mainstream, lithium batteries to replace NiCd/NiMH batteries.
2) LG/Panasonic production capacity shifting to automotive batteries, resulting in the supply chain of international power tool giants shifting to domestic, and the supply share of domestic battery companies is expected to further increase.
(3) Silicone-based materials in the field of power tool batteries began mass production applications, NCM811/NCA + silicone-based materials route will achieve higher multiplier and more resistant to high and low temperature products on the market.
(4) The batteries will be differentiated according to the application (electric capacity, multiplier requirements), and the penetration rate of 21700/26650 in industrial and even professional grade power tools is expected to increase.
