Because of the invention of electric vehicles, the large-scale promotion of lead ingot consumption, the 91/kloc-0 incident in the United States and the Federal Reserve's interest rate cut at the beginning of this century, the US dollar index was greatly suppressed, and the big bull market for commodities lasted for eight years. Lead ingots rose from 6000 to more than 22000. 20 18 battery car consumption has entered an inflection point. The increase of 20 16 is due to lack of ore, and the increase of 20 17 and 20 18 is due to environmental protection. These three driving forces are gone now, and it is normal for lead ingots to continue to fall.

Lead is a silvery white metal with a slight blue color, but it is easily oxidized by oxygen in the air to produce gray-black lead oxide, so the lead we see is often gray.
