Estimating the term…
A lead-acid battery including a case, a plurality of negative and positive electrode plates arranged in the case, a plurality of separators interposed between the negative and positive electrode plates, and a plenum stabilization material disposed within the case to maintain the positions of the electrode plates relative to one another and to other components within the case. The plenum stabilization material includes a compound that (i) is solid during normal operation of the battery and (ii) can undergo reversible physical change in state from solid to liquid when the battery is subjected to or is operated under abnormal conditions.
A sealed, rechargeable lead-acid battery comprising:
A method of increasing the rechargeable cycle life of a sealed, rechargeable lead-acid battery, comprising the step of filling substantially the entire free space within the internal compartment of the battery with a plenum stabilization material that (i) is solid during normal operation of the battery and (ii) can undergo reversible physical change in state from solid to liquid when the battery is subjected to or is operated under abnormal conditions.
A method of inhibiting shorts between internal conductors in a sealed, rechargeable lead-acid battery, comprising the step of filling substantially the entire free space within the internal compartment of the battery with a plenum stabilization material that (i) is solid during normal operation of the battery and (ii) can undergo reversible physical change in state from solid to liquid when the battery is subjected to or is operated under abnormal conditions.
