AI Customer ServiceIn order to provide appropriate decision references for the industry development, patent analysis was carried out. On the basis of Derwent Innovation Index (DII), global patents related to power lithium-ion battery separator were analyzed from aspects of global development scale and trend, technology fields, geographic distribution, top assignees.
The findings show that power lithium-ion battery separator industry has entered fast-growth stage. In branch technology fields, raw materials are the priority research and development (R&D) areas of power lithium-ion battery separator. Japan has applied for a large number of patents and occupied the leading position.
Competition in the lithium-ion battery separator market is fierce. Some of the largest suppliers are Asahi Kasei (24%) and Celgard (11%), Toray (21%), SK (11%), UBE (9%), Sumitomo (7%) and others (17%).
Currently, most commercial separators for lithium-ion batteries are typically porous polyolefin films, both polyethylene and polypropylene. These polymer separators are generally not compatible with some conventional electrolytes that include solvents of high dielectric constants, such as: This is due to the low surface energies of the polyolefins.
A new type of separator for lithium-ion batteries (LIBs) has been developed using ultrathin micrometer-sized sodium borosilicate glass platelets coated directly on a battery electrode with a water-based binder. The coating process is described in detail, demonstrating coating thicknesses of the glass separator of less than 50 µm.
At present, the commercial lithium battery separators in the market are mainly polyethylene- (PE-) and polypropylene- (PP-) based microporous polyolefin separators [ 16 ].
