FLAT-TYPE BATTERY Russian patent published in 2014 - IPC H01M2/30 

FIELD: heating.

SUBSTANCE: flat battery is proposed; it comprises an energy generating element set in the inside space which is formed by the pressurisation of the external outer edges of the elements and a shell, a collector connected to the plate electrode of the energy generating element, and an electrode output led out of the external outer edges of the shell elements. The electrode output is fitted by a conductive segment covering and connected to the collector, and a stress-relieving segment made from the material with its elasticity being higher than that of the conductive segment material. Thus, formation of folds in the collector or the electrode output can be prevented as well as breaks in welded joints due to the difference in the expansion/compression degree between the collector and the electrode output.

EFFECT: provision for operability of a battery in case of deformation.
