Analysis of the energy density of lithium batteries, how to improve the energy density of lithium batteries?

"Energy density" refers to the amount of energy stored in a unit of a certain space or mass matter. The energy density of a battery is the electric energy released by the average unit volume or mass of the battery. The energy density of a battery is generally divided into two dimensions: weight energy density and volume energy density.

Pollution from lead-acid battery production has been repeatedly banned, illegal workshops squeeze formal enterprises

In recent years, the country has successively introduced a variety of policies and measures to regulate the production and recycling of lead-acid batteries, but reporters in Jiangsu, Guangdong, Ningxia and other places found that the pollution caused by lead-acid batteries in the production and recycling process has been repeatedly banned. Especially in the recycling process, on the one hand, regular recycled lead companies generally "cannot get enough food," while on the other, a large number of waste batteries flow into the "black market." Industry insiders believe that lead-acid batteries have serious
