The battery element includes a positive electrode and a negative electrode which are spirally wound or stacked through a separator. The covering material collectively covers the battery and the battery protection circuit board. The rippable portion rips open due to a gas generated from the battery in the event of an abnormal condition to form a gas release hole for releasing the gas outside the battery pack.

摘要： 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 μdm3 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. Thereby, the mixture layer (22b) is impregnated with an electrolyte solution quickly and uniformly, so lithium metal is uniformly precipitated on the whole mixture layer (22b).

摘要： A battery in which the relative positions of a cathode, an anode and a separator are maintained with high precision is provided. A cathode and an anode face each other with a polymer electrolyte including a polymer and a separator in between. In each of the cathode and the anode, an active material layer is disposed on a current collector. Exposed regions where the active material layers are not disposed on the current collectors and the separator are adhered to each other with the polymer electrolyte in between. Thereby, even under a high-temperature environment, the heat shrinkage of the separator can be prevented, and heat generation due to the generation of a short-circuit current can be prevented.
