How to prevent the growth of lead dendrites?

In order to prevent the growth of lead dendrites, the ‘dendrite prevention additives’ such as Na 2 SO 4, (NH 4) 2 SO 4, K 2 SO 4 and MgSO 4 , , , are used as additives in the electrolyte in the VRLA battery manufacturers and Na 2 SO 4 is preferred from the economic standpoint .

What causes the formation of lead dendrites?

The formation of lead dendrites is due to thereduction of PbSO 4 deposited on the separators and the Pb 2+ ions dissolved in the electrolyte.

How can a simulated cell be used to investigate lead dendrite growth?

A simulated cell composed by two pure Pb plates and the absorptive glass mat (AGM) separator is used to investigate the growth of the lead dendrite in the separator, which is verified by analyzing the faulty batteries after the formation and the failure batteries after the usage.

Does lead ion concentration affect dendrite morphology?

And, the inhomogeneous growth along the electrode has been observed. Faster growth and larger dendrites are observed at the corner of the electrode, where the electric field is expected to be stronger. Effects of lead ion concentration in the precursor solution on the dendrite morphology.

What is the diameter of a club shaped lead dendrite?

The diameter of the club-shaped lead dendrites formed in the simulated cell isabout 6–9 μm and their length depends on the coarse fibers and their across points. It indicates that the coarse glass fibers can obviously promote the deposition and growth of PbSO 4 which is reduced to metal lead in the subsequent charge.

How do lead dendrites grow?

We investigate in real time the growth mechanisms of lead dendrites as deposited on the electrodes under an applied potential. TEM images reveal that lead dendrites are developed by the fast protrusion of lead branches in the electrolyte and tip splitting.
