“…Currently, most of lead ash would be directly circled into the melting process (in the furnace). This smelting process would usually be conducted at a higher temperature, that would easily emit large amount of lead particles [16]. Besides the smelting process, a hydro-electrometallurgy route was also applied in the recycling of fly ash generated in spent lead acid battery smelting process [17].…”

This paper mainly investigated on synthesis of a high purity PbS crystal directly from lead ash which was collected from Tin ash removal process (LATR). The LATR was firstly disposed by nitric acid leaching system to generate the lead nitrate solution. The PbS crystal would be prepared by mixing the lead nitrate solution with the sodium sulfide at the room temperature (25 ?C). The effects of molar ratio of HNO3 to Pb in the LATR on Pb leaching efficiency was investigated, demonstrating that the Pb leaching efficiency could attain to 82.9 % at molar ratio of 3. The leaching ratio of As, Cu, Fe, and Al generally increased with increasing molar ratio of HNO3 to Pb in the LATR, while 99.99 wt% of Sn was still left in the residue. In the process of generating PbS crystal from the leaching solution, the yield of PbS crystal was increased with increasing molar ratio of Na2S to Pb in the filtrate. The yield of PbS crystal could up to 93.1% at a molar ratio of 1.5. Overall, this method proved to be an efficient and environmental friendly route for synthesis of high quality PbS crystal directly from the common lead containing waste from the lead ore or secondary smelting factory.

“…The most interesting features of this technology are scalability and flexibility, independent measurement of power and energy, highly efficient laps, high depth of discharge, long life, fast response and reduced environmental impact [6]. In order to reduce the environmental impact of lead-acid batteries, the previous research has been carried out to treat waste and synthesize lead-acid battery electrodes for use in new batteries [7,8]. The application of this battery can be used as energy storage for renewable energy like wind, wave, and solar cell.…”

Renewable energy such as solar energy, waves and wind require batteries as a storage of electrical energy which still has constraints related to voltage, capacity, and energy efficiency. This experiment aims to determine the effect of electrode size on lead-acid dynamic and static battery capacity and energy efficiency. Dynamic and static single cell lead-acid batteries consist of three different electrode sizes, 13.5x7.5 cm 2 (A1); 22.5x7.5 cm 2 (A2) and 32.5x7.5 cm 2 (A3) have been developed. Continuous and simultaneous charge-discharge test using turnigy accucell-6 50 w and chargemaster 2.02 software as graphic programming. Based on experiments, dynamic batteries perform better than static batteries with a difference in capacity of up to 48% and differences in energy efficiency up to 17%. The best performance is obtained on A3 dynamic batteries with an average capacity capacity of 10357 mAh and an average energy efficiency of 81%.
