Lithium batteries "are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began researching lithium-ion batteries. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very high environmental standards. With the development of science and technology, lithium batteries have become mainstream.

With the rapid development of China's economy and the continuous improvement of industrialization level, the amount and variety of solid waste generated are increasing day by day, many of which are hazardous waste. If these hazardous wastes are not disposed of properly, they can seriously endanger human health and even cause irreparable damage to the environment, which hinders sustainable development. In order to protect and improve the ecological environment, prevent and control solid waste pollution, safeguard public health, maintain ecological security, promote ecological civilization construction, and promote sustainable economic and social development. The Solid Waste Pollution Prevention and Control Law of the People's Republic of China plays an important role in legal protection.

In the power industry, flash point testing of oil products is required before the commissioning of new transformers, reactors, and other equipment, as well as after major equipment repairs. During the operation of the equipment, it is necessary to conduct periodic inspections of the oil products. The main purpose is to prevent and detect the presence of light fractions in oil products through flash point testing, thereby determining the risk of fire in oil products and ensuring the safe operation of equipment.
