Each stage of lead–acid battery production greatly impacts the characteristics of the delivered product, as dictated by the intended application. The processes of curing and formation of positive and negative plates are slow due to the conversion of solid-state phases. During battery operation, specific electrochemical processes — in which, electric charges are generated and consumed — act on the positive and negative plates. The research and development laboratory of TASC Ltd. has investigated the effects of externally-applied physical treatment by low energy modulated magnetic field (LEIT) on the electrochemical and crystallization processes that take place in lead‒acid batteries. The LEIT treatment was undertaken during both the production and the operation stages of the batteries. The results demonstrate that when applied during production, LEIT treatment creates conditions for more efficient solid-phase crystallization in the plates. Consequently, there is a reduction in the amount of energy and resources that are necessary for plate formation. Additionally, LEIT treatment during battery operation leads to decreased sulfation on the negative plate, higher charge-acceptance, and improved performance at both extremely high and low temperatures. There has followed further fundamental research on the electrochemical processes in the lead–acid battery under influence of LEITs. The mechanism of this effect and its impact on the electrochemistry of the lead‒acid battery is examined through analysis of the results using mathematical formulation of quantum mechanics, spin chemistry and electrochemistry. Based on the Schrödinger’s equation and the wave functions of the electrochemical system, the impact on the spin-magnetic moments by LEIT is explained.
