“…This shows that the addition of 4BS to plate leads to increase in the conversion rate of lead dioxide. As indicated in previous studies [8][9][10]16], α-PbO 2 is advantageous for the performance of batteries, especially their cycle life, and adding 4BS as crystal seeds increases the content of α-PbO 2 in the lead plates after formation. discharge capacity of the test batteries (B-1 and B-2) with 1 wt% 4BS added is lower about 2.3% than that of the traditional batteries (A-1 and A-2).…”

“…Therefore, research attention has been focused on improving the specific capacity, specific power, charge acceptance, rate capability and cycle life of the valve-regulated lead-acid (VRLA) battery [8]. The most common damage mechanisms for a VRLA battery include positive grid alloy corrosion, positive active material softening and shedding, irreversible sulfating in the negative electrode, water loss, electrolyte stratification, internal short circuit and so on [9,10]. In these damage mechanisms, it is believed that the positive electrode softening and shedding is one of the essential factors and is the main reason for the failure of the positive plate.…”

“…In the early days, many researchers [10] tried to get the increased amount of 4BS in the positive paste by the high-temperature paste manufacture or the high-temperature curing process, so that the mechanical strength of the positive plate could become higher and the cycle life could be lengthened [14,15]. Through the studies of Pavlov et al [16,17], they considered that the mixing lead paste temperature can determine the proportion of 3BS and 4BS in the positive lead paste.…”

Tetrabasic lead sulfate (4BS) was used as a positive active material additive for lead-acid batteries, which affirmatively affected the performance of the battery. Herein, tetrabasic lead sulfate was synthesized from scrap lead paste that was formed through the production process of the lead-acid batteries. This solves the disposing problem of the scrap lead paste that is challenging in the production of the lead-acid batteries. Scrap lead paste was first pre-treated and the 4BS with high purity and crystalline was synthesized by sintering at the temperature of 450°C and hold time of 7 h. As demonstrated by X-ray diffraction and scanning electron microscopy test and Material Studio software calculation, the purity of synthesized 4BS is higher than 98 wt%, small particles have pillar forms and are evenly distributed. Moreover, the synthesized 4BS of 1 wt% was added to the positive lead paste and then valve-regulated lead-acid battery was made after the pasting, curing and formation processes. The effectiveness of the lead-acid batteries after adding 4BS as crystal seeds was evaluated, and the 100% charge–discharge cycle life of the new battery (523 times) was about 1.4 times higher than that of general lead-acid batteries (365 times).

“…Thus, few researchers analyzed the thermal influence (DSC and TGA) on lead-acid battery materials. From this, it was noticed that the temperature rise will minimize the plate material, thereby deteriorates the total lifetime of the battery [6,7].…”

“…In this study, the differential scanning calorimetry (DSC) method was used to measure the differences in energy inputs of a sample as a function of temperature. While the sample and reference materials were exposed to controlled temperature [7], the change of energy inputs was observed between the materials. Additionally, thermogravimetric analysis (TGA) was used to measure the mass of substances in a sample as a function of temperature variations [7].…”

The external (surrounding) temperature variation majorly influences the battery lifetime and performance. The temperature variations lead to failure of individual cells as well as performance of the battery. Lead-acid 12 V/ 7.2 Ah battery is used for the analysis. For heating purpose, two heating coils are fitted inside the wooden chamber. Three thermocouples are connected with DAQ card to measure the temperature. For every 10 full cycle periods, the temperature is increased by 10 °C up to 60 °C. At this stage, the battery starts to explode due to high chemical reactions, fast discharging, and charging cycles. The anode and cathode plates were removed from the battery and analyzed with the help of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). From the DSC results, the change of the heat capacity of the anode and cathode plates is observed. Likewise, TGA result shows the degradation of both anode and cathode plates.
