Patent ID: 11626621

Abstract:
The invention relates to a deformable accumulator comprising: a. a first and a second substrate (1,1′), b. at least one first current collector (2a, 2b, . . . ) deposited on the first substrate, along a curved line, c. at least one second current collector (2a′, 2b′, . . . ) deposited on the second substrate, along a second curved line, d. an anode consisting of a first set of columns (4) deposited on the first current collector (2a′, 2b′, . . . ), e. a cathode consisting of a second set of columns (4′) deposited on the second current collector (2a′, 2b′, . . . ), f. an electrolyte allowing the transfer of the ionic species, the faces of the first and the second substrate facing each other and defining a space (5) occupied by the electrolyte in which the columns of the anode (4) and the cathode (4′) are submerged.
