A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
The lead-acid (PbA) battery was invented by Gaston Planté more than 160 years ago and it was the first ever rechargeable battery. In the charged state, the positive electrode is lead dioxide (PbO2) and the negative electrode is metallic lead (Pb); upon discharge in the sulfuric acid electrolyte, both electrodes convert to lead sulfate (PbSO4).
To support long-duration energy storage (LDES) needs, battery engineering can increase lifespan, optimize for energy instead of power, and reduce cost requires several significant innovations, including advanced bipolar electrode designs and balance of plant optimizations.
This technology strategy assessment on lead acid batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.
The depth of discharge in conjunction with the battery capacity is a fundamental parameter in the design of a battery bank for a PV system, as the energy which can be extracted from the battery is found by multiplying the battery capacity by the depth of discharge. Batteries are rated either as deep-cycle or shallow-cycle batteries.
