Providing a first casing that includes one of an upper cover and a bottom plate of a battery casing, and laminating on the first casing to form a laminated cell.

The secondary battery disclosed herein includes: a battery case; an electrode body accommodated in the battery case; a resin-cured product with which a space between the electrode body and a bottom of the battery case is filled and which is cured; an electrolyte accommodated in the battery case. A thermal conductivity of the resin-cured product is 0.2 W/(m.Math.K) or more.

An electrode assembly includes: a plurality of positive electrodes and a plurality of negative electrodes, alternately and repeatedly stacked; a separator between the positive electrodes and the negative electrodes, respectively, to protrude from the positive electrodes and the negative electrodes and stacked such that surfaces at edges of the separator face each other; and a fixing member including an adhesive layer adhered to the surfaces of the separator.

Provided are an electrode structure and an all-solid secondary battery including the electrode structure, the electrode structure including a cathode layer, an anode layer, and a solid electrolyte layer between the cathode layer and the anode layer, the cathode layer including a cathode current collector and a cathode active material layer on at least one surface of the cathode current collector, the anode layer including an anode current collector and an anode active material layer on at least one surface of the anode current collector, and the solid electrolyte having a margin of about 2% or less of a width of the solid electrolyte layer, at two ends in a width direction, and an insulating layer having a storage elastic modulus (E′) of greater than about 4.0 GPa being at two sides integrally surrounding the cathode layer, the anode layer, and the solid electrolyte layer.

The electrical collector body of the secondary battery includes a resin layer, and metal foils that cover both surfaces of the resin layer. On the metal foils, multiple holes are formed.

A battery module includes a module case, a battery cell assembly that is received in the module case, a heat sink mounted below the module case, and a heat pipe member mounted inside an upper side of the module case. The battery cell assembly includes battery cells, each of which has an electrode lead drawn to one or two sides thereof. The battery cells are stacked along a horizontal direction of the module case such that an edge of each of the battery cells not having an electrode lead is oriented downwardly facing the heat sink. The heat pipe member includes an evaporator and a condenser, the evaporator being formed on a side of the electrode leads of the battery cells, and the condenser being in contact with an inner surface of the module case.

A self-extinguishable film for a lithium-ion battery, comprising a self-extinguishing layer containing a heat-meltable binder and fire extinguishing agent particles.

Embodiments provide a battery cell, a battery, an electric apparatus, and a manufacturing method and system of battery cell.
