Lithium-ion batteries were first developed by the Japanese company Sony Corporation in 1990. It integrates lithium ions into carbon (petroleum coke and graphite) to form a negative electrode (traditional lithium batteries use lithium or lithium alloy as the negative electrode). Commonly used cathode materials are LixCoO2, LixNiO2 and LixMnO4. The electrolyte is LiPF6 + diethylene carbonate (EC) + carbodimethyl nate (DMC).
Petroleum coke and graphite are used as negative electrode materials, which are non-toxic and have sufficient resources. Lithium ions are integrated into carbon, which overcomes the high activity of lithium and solves the safety problems of traditional systems. Lithium batteries. The LixCoO2 positive electrode is charged and discharged. The performance and service life can reach a higher level, which reduces the cost. In short, the overall performance of lithium-ion batteries is improved. Lithium-ion batteries are expected to occupy a significant market in the 21st century.
Yes. Lithium battery electrolyte R&D engineers are responsible for developing electrolyte formulas for different systems and developing new technologies, especially the development of ternary, high voltage, safety electrolytes, silicon anodes andother technologies. The salary is 6,000 yuan, the salary. is relatively high, and there are five insurances and housing fund and weekends are very promising and you can choose to join the company.
