Patent number: 8916291Abstract: An electrolytic solution capable of suppressing the battery swollenness and improving the battery characteristics such as the charge and discharge efficiency and a battery using it are provided. A cathode (21) and an anode (22) are layered with an electrolyte layer (24) in between. The electrolyte layer (24) is gelatinous, containing the electrolytic solution and a polymer compound. The electrolytic solution contains a compound having proton scavenging capacity such as hexamethylenetetramine and hexaethylenetetramine. Thereby, a free acid such as hydrofluoric acid is scavenged, and decomposition reaction of the electrolytic solution or the like is prevented.Type: GrantFiled: February 14, 2006Date of Patent: December 23, 2014Assignee: Sony CorporationInventors: Akira Ichihashi, Gentaro Kano, Karin Tsuda, Fumiko Kimura

Patent number: 7229713Abstract: Provided are an electrode and a battery having superior charge-discharge cycle characteristics and capable of obtaining a higher energy density. The battery comprises a spirally wound electrode body (20) including a cathode (21) and an anode (22) spirally wound with a separator (23) in between. During charge, lithium metal is precipitated on the anode (22), so the capacity of the anode (22) is represented by the sum of a capacity component by insertion and extraction of lithium and a capacity component by precipitation and dissolution of the lithium metal. The anode (22) includes a mixture layer (22b) having a powdered anode active material, and the mixture layer (22b) has liquid absorption properties that when 1 ?dm3 of propylene carbonate is dropped on the mixture layer (22b) at 23° C., a contact angle that the mixture layer (22b) forms with a propylene carbonate drop becomes 10 degrees within 100 seconds.Type: GrantFiled: June 18, 2003Date of Patent: June 12, 2007Assignee: Sony CorporationInventors: Takeru Yamamoto, Gentaro Kano, Hiroyuki Akashi
