State-of-charge determination of lead-acid batteries using wire

During discharging of a lead-acid battery, the lead in the negative electrode active material is converted to lead sulphate, so the total metallic content of the electrode is lowered. The alternating magnetic field does not interact with lead sulphate, so the flux of eddy currents is reduced, resulting in an increase in the measured inductance

How Does Lead-Acid Batteries Work?

Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable. Desulfation is the process of reversing sulfation

6 FAQs about [Magnetic proximity to lead-acid batteries]

Does lead have magnetic properties?

What is the active material of a lead-acid battery?

The positive active material is formed electrochemically from a cured plate, and influences the performance of the lead-acid battery. The electrolyte consists of a sulfuric acid solution, and as the battery discharges, the electrodes are converted into lead sulfate, which reverses when the battery is charged.

Why is magnetic susceptibility important in lithium ion batteries?

The magnetic susceptibility of the active material of LIBs is an important property to explore once the magnetic properties of the transition metal redox processes begin to be correlated to the electrical control (voltage) of LIBs, influencing battery performance.

Why does lead have no magnetism?

The reason behind lead's lack of magnetism lies in its electronic structure. In atoms, the magnetic properties are primarily determined by the arrangement and movement of electrons. Ferromagnetic materials, like iron, have unpaired electrons whose magnetic moments align in the same direction, creating a strong magnetic field.

Are slrfbs a good alternative to lead-acid batteries?

SLRFBs, an allied technology with reports emerging that spent lead-acid batteries can be utilised to make electrolytes to develop SLRFBs, offer a good supply chain of raw materials. In addition to its similarity to the lead-acid battery industry, lead and lead dioxide deposition are known in the electroplating and water treatment industries.

Can a magnet detect lead?

The short answer is no. Magnets detect ferromagnetic materials by their strong attraction, but since lead does not exhibit this property, it remains undetectable by a magnet. This characteristic is crucial in various applications, particularly in situations where the presence of lead needs to be identified without relying on magnetic detection.
