Abstract

Description

Drawing attention as one of main components of EVs as well as small batteries for IT devices and also aiming at the ESS market as well

This report is intended to provide information about patent trends on "separator coating and surface modification" among technologies for secondary battery separators to related companies and research institutes.

Polyolefin-based separators are the most widely used commercial separators. However, the demand for high capacity and output batteries are gradually increasing, which brings about increasing concern about battery safety. In terms of battery safety, polyolefin-based separators, which show severe thermal contraction at high temperature and physical vulnerability, cause a lot of problems. High temperature storage and overcharge of batteries are highly related to thermal stability of separators, and battery safety issues caused by nail penetration and impurities are related to the mechanical properties of separators.

Meanwhile, the issue of wettability with electrolytes is getting serious, as batteries become bigger. In addition, the demand for low-cost batteries is also increasing, as application to electric vehicles is on the track. Considering that separators account for a large portion of the production cost of EV batteries, there is urgent need to solve this problem as well as other technical issues. Thus, there has recently been active effort to solve a lot of problems of existing polyolefin-based separators. This report covers patents on surface modification of separators, which are being developed to improve ceramic composite technologies and affinity with electrolytes.

Among patents that have been filed in Korea, the United States, Japan, and Europe from January 1, 1990 to June 30, 2012, total 1,185 patents were selected, from which 218 effective patents were extracted. Those patents were classified into two categories, coating and surface modification, and then sub-divided into inorganic matters, polymers, and composites for analysis.
