NOVELTY - The battery has an electrode assembly (700) arranged in a battery case. Cathode materials (722, 723) are fixed in a side of a cathode collector that faces separation films (740, 750). An electrode material is fixed in a side of a current collector (721). The separation films are placed between anodes (710, 730) and a cathode (720). Anode materials (712, 713, 732, 733) are fixed in sides of anode collectors (711, 731). The electrode assembly is formed as a winding type structure, a stack type structure, a stack and folding type structure or lamination and stack type structure.    USE - Hybrid-type secondary battery for a battery pack that is utilized as a power source of a device such as notebook, mobile phone, PDP, PMP, MP3 player, digital still camera (DSC), DVR, smart phone, GPS system and camcorder, an electric vehicle (EV), a diesel vehicle, a hybrid electric vehicle (HEV) and a plug-in hybrid electric vehicle (PHEV) (all claimed).    ADVANTAGE - The battery reduces state of charging difference between multiple secondary battery packs so as to reduce self-discharge rate of the battery, so that safety and service life property of the battery can be improved. The battery efficiently reduces heat so as to prevent deterioration of the battery.    DETAILED DESCRIPTION - The anode material is divided into high power and low capacity type anode material and low power and high-capacity type anode material, where the high power and low capacity type anode material is made of lithium manganese oxide, lithium-iron phosphorus oxide, lithium nickel network, cobalt oxide or lithium nickel cobalt aluminum oxide, and the low power and high-capacity type anode material is made of lithium cobalt oxide, cobalt oxide, lithium nickel cobalt aluminum oxide or over-lithiated oxide. The cathode material is divided into high power and low capacity type cathode material and low power and high-capacity type cathode material, where the high power and low capacity type cathode material is made of amorphous carbon, or graphite system cathode material, and the low power and high-capacity type cathode material is made of graphite, silicon group or tin. INDEPENDENT CLAIMS are also included for the following:    (1) a battery pack    (2) a device.
