A rechargeable cell 100 comprises an outer casing 38 and a roll 32 comprising layers of active and insulator material disposed within the outer casing. The rechargeable cell additionally comprises an externally accessible hollow core 52 which enables central cooling of the rechargeable cell. The rechargeable cell 100 is used alongside a cooling system 200. The system 200 comprises at least one finger 206 configured and arranged for insertion into the externally accessible hollow core 52 of the cell, the finger(s) comprising a first pathway A for an inbound flow of coolant and a second pathway B for an outbound flow of coolant. In a further aspect, the cooling system comprises a block of heat conductive material with a plurality of bores 204, each of which is able to receive a rechargeable cell 100 (fig 5). Methods of manufacturing the rechargeable cell are also described, in which layers of active and insulator material are wound around the hollow core 52 which acts as a mandrel before insertion into the outer casing 38 (fig 6), or in which the hollow core 52 is inserted into a cell already including the rolls 32 of material within the outer casing 38 (fig 7). |
