【Summary Description】Since the beginning of this year, the market for new energy vehicles and lithium batteries has continued to be hot, and the prices of upstream raw materials for lithium batteries have risen rapidly. Among them, the cathode material is the most critical raw material for lithium batteries, including lithium carbonate, lithium hydroxide and the like. At present, lithium carbonate, lithium hydroxide, electrolyte and so on have risen to varying degrees, and some raw materials have increased by more than 200 compared with the beginning of this year. "One product is hard to find" has become the current status of raw material procurement for lithium battery companies, and what's more, many raw material manufacturers have placed orders until next year.
Therefore, understanding the development of China's lithium-ion power battery industry is of great significance to help readers distinguish between true and false new energy vehicles, and to my country's new energy vehicles and even sustainable development strategies. Based on the global patent database of Wisdom Bud, the author analyzes the basic principles and advantages and disadvantages of lithium batteries, and predicts the technological development prospects of lithium-ion power batteries from the perspective of patents, so as to continue to pay attention to the future industrial development.
Ternary and lithium iron phosphate have become the mainstream cathode materials for electric vehicles
Simple one-sentence overview The definition of lithium ion battery: "Use the concentration difference of lithium ion for energy storage and discharge." Secondly, from the basic composition of lithium-ion batteries, it is mainly composed of four major raw materials: positive electrode, negative electrode, electrolyte and diaphragm. Under the current technical conditions, the cathode material is not only the key factor that determines the performance of the battery, but also the most expensive part of the lithium battery, which has a direct impact on the energy density, service life and safety of the battery pack. However, the gap between different lithium battery cathode materials is obvious, and the application field is not the same. It can be said that not all lithium battery cathode materials are suitable for new energy vehicles.
