Arrangement of electrochemical cells and circuit board

摘要

The application describes a cell unit which includes at least two flat electrochemical cells (1',1'',1''') and a circuit board (5), the cells being folded onto one or both sides of the circuit board whereby the circuitry on the circuit board is protected. Preferably, the cells and the circuit board have the same lengths and widths. The cells may be provided on two or more edges of the circuit board and optionally two cells are connected at the same edges on the board. A means of connecting electrochemical cells to a circuit board is also described wherein protruding parts (14) of the cell, at the terminal end, are bonded to the circuit board.
