| abstract |
The present invention comprises a shell (1) delimiting a space (2) filled with an electrolyte (3) and a series of at least two different electrochemical systems (S 1 , S1) selected from supercapacitors, hybrid supercapacitors and accumulators. S 2 ). The series relates to an electrochemical cell in which at least two different electrochemical systems are arranged in a space (2) filled with electrolyte (3). The invention also relates to a system for storing and recovering electrical energy including such an electrochemical cell and a vehicle, in particular a hybrid vehicle, including such a system for storing and recovering electrical energy. |
