Synthesis of lead(II)iodide (PbI2) (IMAGE) Optica Caption Researchers developed an environmentally friendly method to turn lead from used lead acid batteries into photodetectors operating in the UV-visible band. They created lead(II)iodide (PbI2) microcrystals from the lead paste found in batteries using a one-pot solution process.
