NOVELTY - The cell (200) has an anode (211) located at a side of an electrode assembly (250). A cathode (221) is positioned at another side of the electrode assembly. A separation film (231) is adhered between the anode and the cathode. The electrode assembly is mounted in an upper part of a storage unit that is installed at a side of a battery case (241). An anode terminal is made to contact with a cathode terminal that is protruded to an outer periphery of the electrode assembly. An insulating material part (271) is located between the electrode assembly and the battery case.    USE - Battery cell e.g. secondary lithium battery cell and lithium ion polymer battery cell, for use in an electronic device e.g. mobile phone, tablet computer, notebook computer and power tool, a vehicle e.g. electric vehicle, hybrid electric vehicle and plug-in hybrid electric vehicle, and a power storage system.    ADVANTAGE - The separation film is adhered between the anode and the cathode, and the electrode assembly is mounted in the upper part of the storage unit that is installed at the side of the battery case so as to simplify a configuration of the cell and prevent direct contact of the anode and the electrode assembly, so that firing or explosion of the cell due to short-circuit can be prevented, thus improving safety effect about the cell.    DETAILED DESCRIPTION - The insulating material part is made of insulating property paint, parafilm or foam rubber material. The insulating property paint is acrylonitrile-butadiene rubber, stylene butadiene rubber, isobutylene isoprene rubber, chloroprene rubber or ethylene propylene diene monomer. The foam rubber is natural rubber or synthetic rubber. The synthetic rubber is styrene-butadiene rubber, polychloroprene rubber, nitrile rubber, butyl rubber, butadiene rubber, isoprene rubber, ethylene free pylene rubber, polysulfide rubber, silicone rubber, fluoro rubber, urethane rubber or acryl rubber. An INDEPENDENT CLAIM is also included for an electronic device.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a battery cell.
