6 FAQs about [Phosphoric acid battery positive electrode material field]

Does phosphoric acid affect battery performance?

Voss and Meissner reviewed the effect of phosphoric acid on the performance of the lead acid battery. Phosphoric acid significantly reduced the shedding of positive active material and thus suppresses the anodic corrosion of the grid material and reduces self-discharge.

Why do we add phosphoric acid to lead/acid batteries?

2. Phosphoric acid The addition of phosphoric acid to the electrolyte of lead/acid batteries has been practised since the 1920s [59]. The main motivations were reduction of sulfation (espe- cially in the deep-discharge state) and extension of cycle life by reduced shedding of positive active material.

Does phosphoric acid affect the performance of gelled lead/acid electric-vehiicle batteries?

The influence of the addition of phosphoric acid to the electrolyte on the performance of gelled lead/acid electric-vehiicle batteries is investigated. This additive reduces the reversible capacity decay of the positive electrode significantly which is observed upon extended cycling when recharge of the battery is performed at low initial rate.

Which phosphoric acid is used as a counter electrode?

A platinum electrode of large surface area was used as the counter electrode. The AR grade sulphuric acid was diluted to 4.5 M using triple distilled water and was used as the electrolyte. Various concentrations of phosphoric acid ranging from 0.05 to 0.2 M were used as the additive throughout the studies.
