Briefly describe the reason for the explosion of lithium battery diaphragm

1. Demand side: The demand for lithium batteries in the new energy automobile industry chain continues to rise at a high speed, bringing a high level of prosperity in the entire lithium battery industry chain, especially in the field of lithium battery materials, which is the core part of the entire industry technology. In 2016, the industry output growth rate of the four core materials of lithium batteries: positive electrode, negative electrode, separator and electrolyte exceeded 50%. Among them, the growth rate of diaphragm output value exceeds 100%. From 2016 to 2020, the demand for diaphragm is expected to increase from 20% to 60%. In 2020, the demand for diaphragm is expected to exceed 3 billion square meters! 2. Technical side: Lithium battery separators are divided into dry process and wet process. They have been monopolized by foreign countries before their high technical barriers. Currently, inspired by the policy of new energy vehicles, the technology of the domestic separator industry continues to advance. The domestic production rate of diaphragms has reached over 86%, and dry-process diaphragms have already been fully localized; shipments of domestic wet-process diaphragms have also increased significantly. Technological progress has promoted the emergence of a number of star diaphragm companies in China. With the siphon effect, more and more technology companies will join the diaphragm processing army. 3. News: Apple and CATL (Ningde Times New Energy) are cooperating on a new energy vehicle power lithium-ion battery project based on a non-disclosure agreement. Regarding lithium battery materials, it is a great benefit! Disclaimer: Some pictures and content of articles published on this site are from the Internet.
