ABSTRACT:
A flat accumulator device (10) includes a planar electrochemical cell with at least two planar electrodes (2, 2') having opposite polarities disposed on either one of the two sides of an electrolyte material (3, 4), a planar housing having planar parts (1, 1') and enveloping the planar electrochemical cell, and electrical contacts (30, 30') of the electrodes forming external electric terminals fixed in a moisture-proof manner to the planar parts of the housing. In this device, the flat accumulator includes a security portion (31, 32; 31', 32') which forms a circuit breaker that can be triggered by a short-circuit produced between the electric terminals of the housing.
