“…Ridge-type growth is observed mainly on the (110) plane when deposited from a moderately pure solution (2)(3)(4). However, ridges are also observed on the surface of different orientations when the solution is not pure (5)(6)(7). Very careful experiments were carried out from highly purified solutions to study the pyramidal growth on the (110) single crystal plane of copper and attempts were made to explain the origin of ridge growth.…”

“…Most notable of these is the classical problem of localized attack of segregated materials such as the eutectic structure or intermetallic compounds. This effect has been well documented for the lead-acid system (6)(7)(8)(9)(10)(11) and is particularly damaging not only for the effects on mechanical integrity but also for its contribution to internal resistance, a factor which limits battery performance. Moreover, other effects such as active mass to grid bonding, active mass morphology, and reduced overpotentials for gassing have all been attributed to alloying, particularly antimony (1).…”

A radical change in microstructure was examined for its effect on the mode of corrosive attack and corrosion rate for a 5 weight percent antimonial lead alloy. Metallography on as‐cast microstructures indicates a transition from interdendritic to general attack with increasing overpotential. The potential region for general attack corresponds to a breakdown in the passivating abilities of PbO2 and is marked by a sharp rise in the corrosion current. A simple heat‐treatment, which alters the structure of the eutectic material, reduces interdendritic attack over the entire potential region studied.

На микроструктуру сплавов и степень коррозии оказывают влияние условия их приготовления [4]. Кроме того, при циклировании батарей на основе свинцово-кальциевых сплавов, так же как и свинцовых решёток, возникают проблемы с перезарядом и наблюдается быстрое снижение ёмкости после нескольких первых десятков циклов [5][6], особенно при заряде постоянным напряжением.…”

“…The greater hardness of Pb-Ca alloys is achieved by the development of two-phases, a precipitate of Pb,Ca dispersed in a Pb-Ca solid solution (8). Unless uniform dispersions of small particles are produced during manufacture, highly localized and severe corrosion can occur (9). When attack is localized at grain and phase boundaries, accumulated corrosion products act as stress concentrators (10).…”

The positive grid in stationary lead-acid batteries

The highly oxidizing and acidic environment experienced by the positive plate in telecommunications lead-acid batteries severely limits the choice of positive grid materials. Currently, grids are made from pure lead or lead-based alloys. Although long-lived batteries have been obtained using pure lead grids with complex designs, the need for thick grids coupled with the high density of lead results in batteries with low energy density. Energy density improvements could be achieved if thinner lead grids or thin grids made from less dense materials could be employed. Many approaches t o controlling the corrosion and growth rate of lead-based grids as well as to the use of alternative materials have been reported in the literature. This paper provides an indepth evaluation of the strengths and weaknesses of these approaches based on the characteristics associated with a viable grid material.
