Abstract: An assembly of batteries includes a first battery and a second battery electrically connected in parallel. The first battery is configured to deliver a battery capacity in a first power supply voltage range. The second battery is configured to deliver a battery capacity in a second voltage range. An upper limit of the second voltage range is set between upper and lower limits of the first voltage range. In an operating system, if supplied battery power falls below a threshold, the parallel connected first and second batteries are disconnected from the load.

Abstract: The invention relates to a method for producing a material for a composite electrode. The method is intended for the preparation of a composite material consisting of an active electrode material M1, a material C1 conferring electronic conductivity, an organic binder and a salt, said binder comprising a polymer P1 having an O, N, P or S heteroatom mass content of 15% or higher, a polymer P2 having an O, N, P or S heteroatom mass content of 5% or less, and a nonvolatile liquid organic solvent S1. It includes a step consisting in preparing a viscous solution containing at least one polymer P1, at least one polymer P2, a material C1, an active electrode material M1 and at least one nonvolatile solvent S1, and a step consisting in forming a film from the viscous solution obtained.
