Breaking the technical barriers of L1022 battery materials, my country's building materials industry has successfully realized the localization of L1022 battery separators

As one of the key materials of lithium-ion batteries, lithium-ion battery separators are a high-value-added material with the highest technical barriers among lithium-ion battery materials, and are also the last key material to be localized among lithium-ion battery materials.

Recently, my country National Building Materials Group Co., Ltd.'s China National Materials Lithium Membrane Co., Ltd. held a trial production promotion meeting for the first production line of the "240 million square meters of lithium-ion battery separator construction project" in Tengzhou, Shandong, marking that my country National Building Materials Group has broken the foreign monopoly and successfully realized the localization of the last key material in lithium-ion battery materials. It also marks that my country National Building Materials Group's lithium-ion battery separator research and development and production capacity have taken a leading position in the world.

As one of the key materials of lithium-ion batteries, lithium-ion battery separators are a high-value-added material with the highest technical barriers among lithium-ion battery materials, and are also the last key material to be localized among lithium-ion battery materials.

The first phase of the project built a 200 million square meter lithium-ion battery separator production line and a 40 million square meter lithium membrane coating production line. my country Building Materials will take this project's trial production as an opportunity to strive to build the lithium membrane industry into a pillar industry with industry influence, supply the market with better quality lithium-ion battery separators, and make greater contributions to the country's new energy vehicle plan and new materials industry development.
