This arrangement may allow the battery to be shaped to fit a form factor of the electronic device. This arrangement also may allow one or more of the cells to be selectively removed from the plurality, which may be desirable from a manufacturing perspective.
High capacity battery cell employed with two or more unit cells
Disclosed herein is a secondary battery including two or more stacking-folding type cells (‘unit cells’) manufactured by winding small-sized electrode assemblies (‘bicells’) constructed in a stacking type structure in which electrodes having the same polarity are located at opposite sides of each electrode assembly and small sized electrode assemblies (‘full cells’) constructed in a stacking type structure in which electrodes having different polarities are located at opposite sides of each electrode assembly using a long separator sheet, wherein the unit cells are mounted in a battery case, each unit cell has one or more electrode terminals protruding from each end of each unit cell, and the unit cells are mounted in a receiving part of the battery case such that the unit cells are arranged in a stacking arrangement structure or a plane arrangement structure while the electrode terminals of the unit cells are connected with each other.
Battery cell having improved thermal stability and middle or large-sized battery module employed with the same
Disclosed herein is a battery cell constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case formed of a laminate sheet including a resin layer and a metal layer while the electrode assembly is connected to electrode terminals extruding out of the battery case, wherein the battery case is provided at an outer circumferential end thereof with a sealing part formed by thermally welding upper and lower parts of the laminate sheet, and a sheet-type member (‘a thermally conductive sheet’) to accelerate the dissipation of heat from the battery cell extends to the sealing part while the thermally conductive sheet partially covers the battery cell.
A secondary battery is disclosed. In one aspect, the battery includes an electrode assembly including i) a positive electrode plate on which a positive active material is formed, ii) a negative electrode plate on which a negative active material is formed, and iii) a separator separating the positive and negative electrode plates. The battery also includes a can accommodating the electrode assembly, wherein the can has an inner surface facing the electrode assembly, an inner active material layer formed on the inner surface of the can and a securing layer covering the inner active material layer.
