Patent number: 8728664Abstract: An anode for a lithium secondary battery contains an active material and a binder mixture. The active material can occlude or liberate lithium. The binder mixture includes a synthetic rubber-based latex-type binder, a cellulose-based thickener, and an acrylamide-based water-soluble polymer. The adhesive forces among electrode materials and between the electrode materials and a current collector are greatly increased. As a result, the number of battery defects, which are caused by low adhesive forces in the electrode plate manufacturing process, in particular, a rolling process, can be unexpectedly decreased. At the same time, high-rate discharge characteristics can be improved by decreasing the resistance at the interface between the electrode materials and the current collector.Type: GrantFiled: December 30, 2004Date of Patent: May 20, 2014Assignee: Samsung SDI Co., Ltd.Inventors: Jin-Hwan Park, Tae-Byoung Oh, Dae-Ho Lee, Kil-Won Cho
