In recent years, environmentally-friendly processes operating at near ambient temperatures show a good prospect for the recovery of spent lead-acid batteries, including electrowinning, organic acid leaching-calcination, and alkaline leaching-crystallization processes.
MIT researchers have developed a simple procedure for making a promising type of solar cell using lead recovered from discarded lead-acid car batteries—a practice that could benefit both the environment and human health. As new lead-free car batteries come into use, old batteries would be sent to the solar industry rather than to landfills. And if production of this new, high …
Compared with lead-acid batteries and nickel-cadmium batteries, lithium-ion batteries do not contain toxic heavy metal elements, such as chromium, mercury, and lead, and are recognized as green energy sources with relatively low environmental pollution. They are also new energy products advocated by the Chinese government. However, the cathode and anode materials …
