How to improve the cycle life of a lead-acid battery?

Key factors in the improvement of cycle life of the valve-regulated (maintenance-free) lead-acid battery have been shown to be, compression of the active mass by the separator, the construction of the absorptive glass mat separator and the nature of the charge regime employed to recharge the battery after use.

How do you recondition a lead acid battery?

To recondition a lead acid battery, you need to remove the lead sulfate buildup from the plates and restore the electrolyte solution. This process involves cleaning the plates, adding distilled water and sulfuric acid to the electrolyte, and charging the battery to its full capacity.

Can Pani improve the cycle life of lead-acid batteries?

In the present work, a simple and low-cost method is applied to modify lead grids of the negative plate in the Lead-Acid batteries by PANI. The outcomes indicate that a layer of PANI, deposited between the current collector and negative active materials, could increase cycle life of the Lead-Acid cells, considerably.

What is a lead acid battery?

A lead acid battery typically consists of several cells, each containing a positive and negative plate. These plates are submerged in an electrolyte solution, which is typically a mixture of sulfuric acid and water. The plates are made of lead, while the electrolyte is a conductive solution that allows electrons to flow between the plates.

What is a deep cycle lead acid battery (VRLA)?

One subcategory of the deep cycle Lead-Acid batteries is Valve Regulated Lead-Acid battery (VRLA), in which the plates are wrapped around with porous absorptive glass mat (AGM) separators and compressed to a definite pressure.

How will a lead-acid battery improve the marketability of electric vehicles?

The work is expected to result in further improvements to cycle life and specific energy of the lead-acid battery and a consequent reduction in running costs. This will in turn make the performance and COSt of an electric vehicle more attractive and hence improve their marketability.
