What is the future of cylindrical lithium-ion batteries? You can take a look at the data. According to data from authoritative research institutes, in November 2018, the installed power of cylindrical batteries was about 1.29GWh, accounting for about 14%, up by more than 3 percentage points compared with last month. It can be said that the prospect is bright, from the earliest cylindrical lithium battery is invented by a Japanese company in 1992 18650 lithium battery, because of the 18650 cylindrical lithium battery has a long history, so the market penetration rate is high, cylindrical lithium battery adopts mature winding process, high degree of automation, stable product quality, relatively low cost. There are many types of cylindrical lithium battery, such as 17490, 14650, 18650, 26650 and so on. Cylindrical lithium battery is more popular in The lithium battery enterprises in Japan and South Korea. There are also large-scale enterprises in China that produce cylindrical lithium battery and cylindrical battery sleeve membrane all-in-one machine, as will be mentioned below.

With the rapid development of domestic electric vehicle market, vehicle manufacturers have put forward higher requirements for power battery in energy density, manufacturing cost, additional product, cycle life and other aspects. On the premise of a great breakthrough in the field of raw materials, appropriately increasing the volume of cylindrical batteries to obtain more battery capacity and enhance brand awareness becomes a direction to explore.
