Integrated busbar, also known as wiring harness integrated parts (CCS), is an integrated circuit connector, which is widely used in the field of new energy battery. Its raw materials are mainly composed of flexible circuit boards, cover film PI and pure adhesive epoxy resin, etc. In 2021, the output of CCS in the domestic power battery field was about 8.6 million, and it is expected that the output will reach 16 million in 2022, with a year-on-year growth of about 86%. Flexible circuit board (FPC) refers to a highly reliable, excellent flexible printed circuit board made of copper-clad substrate (CCL) as the base material. According to its structural differences can be divided into single-layer FPC, double-layer FPC, multi-layer FPC and rigid-flex combination FPC. 2021 domestic FPC production in the field of power batteries is about 13 million, and the output is expected to reach 18 million in 2022, an increase of about 38% year-on-year. New energy battery heating film is mainly used to create a heated environment when the battery is in use, to enhance the temperature of the battery environment, to protect the battery life and longer battery life, according to the raw materials can be divided into PI heating film, PTC heating film, epoxy plate heating film, silicone heating film, etc., the domestic production of new energy battery heating film in 2021 is about 48 million, is expected to 2022 production will reach 70 million, an increase of about 46% year-on-year. growth of about 46%. The main functions of new energy battery thermal insulation cotton include protection, thermal insulation buffer, waterproof, fire prevention, anticorrosion, insulation, etc. In 2021, the domestic production of new energy battery thermal insulation cotton was about 660 million pieces, and it is expected that the output will reach 1 billion pieces in 2022, with a year-on-year growth of about 51%.
