What causes internal shorts in lead-acid batteries?
Internal shorts in lead-acid batteries generally fall into two categories: hard shorts and soft shorts. Hard shorts are typically caused by paste lumps resulting from manufacturing defects. Soft shorts are the result of excessively deep discharges where the specific gravity becomes so low that lead begins to dissolve into the electrolyte.
What causes lead-acid battery failure?
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
Are lead-acid batteries a problem?
Lead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. Among the most critical problems are corrosion, shedding of active materials, and internal shorts.
How does a lead-acid battery shed?
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
How does corrosion affect a lead-acid battery?
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
Why do lead-acid batteries have a short circuit?
Several factors contribute to the development of internal shorts in lead-acid batteries: Plate-to-Plate Contact: Over time, the separation between the positive and negative plates can deteriorate, allowing them to make contact and create a short circuit.
