Abstract
A composition for prolonging battery life by reducing water loss and the degradation of properties due to dendritic precipitation, is refreshingly added to a battery electrolyte. By the refreshment of the composition, battery cycle life is substantially increased while degradation of the internal battery components is substantially reduced.
Claims60
An apparatus for prolonging the useful life of a battery containing an electrolyte comprising:
- a battery life extending composition;
- and
- means for refreshingly incorporating the battery life extending composition into the electrolyte in an effective amount to substantially maintain an active concentration of the battery life extending composition in the electrolyte, the means for refreshingly incorporating the battery life extending composition being a reservoir, connectable to the battery, the reservoir having a and valve means for periodically adding the battery life extending composition and replenishment water to the electrolyte.
An apparatus for prolonging the useful life of a battery containing an electrolyte comprising:
- a battery life extending composition;
- means for refreshingly incorporating the battery life extending composition into the electrolyte in an effective amount to substantially maintain an active concentration of the battery life extending composition in the electrolyte, the means for refreshingly incorporating the battery life extending composition being a reservoir having a first tube connectable to the battery, the reservoir having a size sufficient to receive replenishment water therein, a container for receiving the battery life extending composition therein, the container having a second tube connectable to the first tube, mixing means for forming a mixture of the battery life extending composition and the replenishment water, first flow control means for adding the battery life extending composition to the replenishment water and second flow control means for periodically adding the mixture to the electrolyte.
