Abstract
For the effective removal of Joule heat from the interior of a high-performance lead battery, especially those with a fixed electrolyte, at least one of the negative grid plates which participate in the development of the electrodes are provided with a U-shaped tube which surrounds and is attached to the grid, in place of the usual grid frame, and through which a coolant circulates. Especially advantageous due to its capacity to conduct heat is a combination of a lead-coated, copper mesh grid and a copper tube, with a residual strip of unexpanded copper sheeting attached to the grid mesh along the remaining upper section of the frame, and developing the conducting lug.
