Abstract: An electrode and an electrode material for lithium electrochemical cells are disclosed. The electrode material is in powder form and has a particle size distribution wherein the measured particle size distribution of the electrode material has a median size D50 ranging from 1.5 ?m and 3 ?m, a D10?0.5 ?m, a D90?10.0 ?m, and a calculated ratio (D90/D10)/D50?3.0 which is indicative of a peak of the measured particle size distribution on the left of the median D50 which improves the loading and energy density of the electrode produced with this electrode material powder.

Abstract: The application relates to a battery including a pack of modules, each containing rechargeable cells in series, the battery including means for measuring the voltage and/or the temperature of at least one module. According to the application, the battery includes means for computing, based on the voltage and/or temperature measured by the measuring means and on a recorded characteristic of the discharge current and/or regeneration current of the battery, a maximum discharge and/or regeneration current limit of the pack. The battery also includes a transmission means for transmitting to the outside the information on the maximum discharge and/or regeneration current limit of the pack.

Abstract: The application relates to a power battery module, including rechargeable cells having a nominal operating charging temperature, greater than 20° C. According to the application, the module includes a circuit for managing charging of the cells which further includes: two external charging terminals for charging of the cells, wherein at least one, called second charging terminal, of the two external charging terminals is distinct from the external use terminals, first interruption/connector between the second charging terminal and one of the use terminals, second device between the charging terminals and the heating element to connect, at least in the first interruption position, the charging terminals to a heating element of the cells.
