SEPARATOR AND LITHIUM BATTERY INCLUDING THE SAME

This application relates to a separator and a lithium battery employing the same. In one aspect, the separator includes a porous substrate and a coating layer disposed on a surface of the porous substrate. The coating layer includes organic particles, a first binder, and inorganic particles. The organic particles have a first melting point of about 100 DEG C to about 130 DEG C. The first binder has a second melting point higher than the first melting point by about 30 DEG C or more. The organic particles are coated by or embedded in the first binder. The separator can maintain a network structure even at a high temperature, making it possible to improve the high-temperature stability of a lithium battery by employing the separator, as well as delaying a rapid increase in temperature and heat generation when a shutdown occurs. 本申请涉及隔板和采用隔板的锂电池。在一个方面中，隔板包括多孔基板和设置在多孔基板的表面上的涂层。涂层包括有机颗粒、第一粘结剂和无机颗粒。有机颗粒具有约100℃至约130℃的第一熔点。第一粘结剂具有比第一熔点高约30℃或更高的第二熔点。有机颗粒被第一粘结剂包覆或者嵌入第一粘结剂中。隔板即使在高温下也可维持网状结构，使得有可能通过采用该隔板来改善锂电池的高温稳定性，以及在关
