Battery structure with internal thermal control

Abstract:

A battery structure is provided. The battery structure includes a casing, a jelly roll assembly, electrodes, insulation and a thermal control feature. The casing includes an internal tube defining a central hole. The jelly roll assembly is disposed with an electrolyte in an annular space about the internal tube within the casing. The electrodes are electrically coupled to the jelly roll assembly and disposed to extend out of the casing. The insulation is disposed to insulate the jelly roll assembly and the electrodes from the casing. The thermal control feature is communicative with the central hole and configured to control battery structure temperatures proximate to the central hole.
