The first Ni–Cd battery was created by Waldemar Jungner of Sweden in 1899. At that time, the only direct competitor was the lead–acid battery, which was less physically and chemically robust.With minor improvements to the first prototypes, energy density rapidly increased to about half of that of primary batteries, and significantly greater than lead–acid batteries.

Cadmium and lead stock solutions were prepared by dissolving Cd(NO 3) 2.4H 2 O and Pb(NO 3) 2 (98%, Sigma Aldrich) in deionized water (18.2 MΩ). Concentrations of the prepared stock solutions were confirmed by comparison with 1.0 g L −1 commercial standards solutions (Perkin Elmer). Nitric acid (HNO 3) from Merck was purified in house by sub-boil
There is a growing need to develop novel processes to recover lead from end-of-life lead-acid batteries, due to increasing energy costs of pyrometallurgical lead recovery, the resulting CO 2 emissions and the catastrophic health implications of lead exposure from lead-to-air emissions.
The requirement for a small yet constant charging of idling batteries to ensure full charging (trickle charging) mitigates water losses by promoting the oxygen reduction reaction, a key process present in valve

This study reports the adsorption capacity of lead Pb2+ and cadmium Cd2+ of biochar obtained from: peanut shell (BCM), "chonta" pulp (BCH) and corn cob (BZM) calcined at 500, 600 and 700 °C, respectively. The optimal adsorbent dose, pH, maximum adsorption capacity and adsorption kinetics were evaluated. The biochar with the highest Pb2+ and Cd2+
Implementation of battery man-agement systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life.

As the pH increased, the reduction in H 3 O + concentration and the deprotonation of functional groups led to a rapid increase in the adsorption of Pb, Cd, and Zn by MgFe–LDH@BB [30,31]. The maximum adsorption capacities of Pb, Cd, and Zn by MgFe–LDH@BB at pH 6 were 997.5, 470.6, and 356.6 mg·g −1, respectively. To achieve the

Nevertheless, forecasts of the demise of lead–acid batteries (2) have focused on the health effects of lead and the rise of LIBs (2). A large gap in technologi-cal advancements should be seen as an opportunity for scientific engagement to ex-electrodes and active components mainly for application in vehicles.
The recovery of lead acid batteries from sulfation has been demonstrated by using several additives proposed by the authors et al. From electrochemical investigation, it was found that one of the main effects of additives is increasing the hydrogen overvoltage on the negative electrodes of the batteries.

In principle, lead–acid rechargeable batteries are relatively simple energy storage devices based on the lead electrodes that operate in aqueous electrolytes with sulfuric acid, while the details of the charging and discharging processes are complex and pose a number of challenges to efforts to improve their performance.
It is also well known that lead-acid batteries have low energy density and short cycle life, and are toxic due to the use of sulfuric acid and are potentially environmentally hazardous. These disadvantages imply some limitations to this type of battery.
