The role of arsenic in lead-acid batteries

Aging mechanisms and service life of lead–acid batteries

The addition of arsenic (0.15–0.25%) improves the corrosion resistance of lead–antimony alloys drastically. As will be discussed later, valve-regulated batteries must be operated at considerably higher float voltages than tubular (flooded) batteries, in order to avoid sulfation of the negative plates. The float voltage recommended for valve-regulated batteries is

6 FAQs about [The role of arsenic in lead-acid batteries]

How does arsenic affect a lead-antimony grid?

Does arsenic affect electrode capacity?

When the active-mass density is close to the critical value (d = 3.80 g cmWs), however, the influence of arsenic is not observed. Indeed, a decrease in capacity occurs. An increase in the arsenic concentration of the alloy from 0.2 to 0.8 wt.% has only a slight influence on the electrode capacity after 20 cycles.

Can arsenic trioxide be used to treat acute promeylocytic leukemia?

Recently, arsenic trioxide has been approved by the Food and Drug Administration as an anticancer agent in the treatment of acute promeylocytic leukemia . Its therapeutic action has been attributed to the induction of programmed cell death (apoptosis) in leukemia cells .

Why is corrosion layer formed during battery operation?

The corrosion layer is formed during battery operation due to the thermodynamic instability of the grid at the positive-plate potentials. During charge and discharge, the elec-tric current flows consecutively through these elements.

What factors affect lead absorption?

Lead absorption is influenced by factors such as age and physiological status. In the human body, the greatest percentage of lead is taken into the kidney, followed by the liver and the other soft tissues such as heart and brain, however, the lead in the skeleton represents the major body fraction .

Do metals interact with cadmium & arsenic?

A recent review of a number of individual studies that addressed metals interactions reported that co-exposure to metal/metalloid mixtures of arsenic, lead and cadmium produced more severe effects at both relatively high dose and low dose levels in a biomarker-specific manner .
