Application of boron trioxide (B2O3,boric oxide) for lithium battery industry

Boron trioxide (B2O3,boric oxide) with chemical formula B2O3, commonly known as Anhydrous boric acid, appears gray or white powder, the surface has a sense of grease, strong moisture absorption, it can be completely miscible with metals, copper, silver, aluminum, tin, arsenic oxides, with a high melting point (about 450°C) and good chemical stability. It can also be used as the substrate material for lithium batteries. Secondary lithium-ion batteries are widely used in the field of mobile communications, electric locomotives and other fields, and in the field of new energy research. The following is the specific application of boron trioxide (B2O3,boric oxide)in the lithium battery industry:

Firstly:as a positive electrode material for lithium battery: boron trioxide (B2O3,boric oxide)has certain conductivity and chemical stability, and can be used as a promising positive electrode material for lithium ion batteries. Studies have shown that boron trioxide(B2O3,boric oxide) can store and release electrical energy through chemical reaction with lithium ions, has a high specific capacity and a long cycle life, and can play an important role in improving battery performance ‌.

Secondly, it can improve battery cycle performance:adding a small amount of boron trioxide (B2O3,boric oxide)to the electrolyte of lithium battery can significantly reduce the capacity loss of the battery in the cycle and improve the cycle performance of the battery. This is because boron trioxide(B2O3,boric oxide) may prevent the breakdown of the electrolyte around the electrode, thus reducing the decline of the battery's capacity during the cycle.However, when the amount of boron trioxide (B2O3,boric oxide)is more than 1% of the weight of the electrolyte, it will reduce the thermal stability of the electrolyte, and boron trioxide(B2O3,boric oxide) is easy to react with water to produce boric acid, which is adverse to the battery, it is necessary to pay attention to the amount of boron trioxide (B2O3,boric oxide)added, so it is important to keep boron trioxide (B2O3,boric oxide)from moisture while using.

Today, facing the rapid development of science and technology, lithium batteries, as an important energy storage device, are widely used in electronic equipment, electric vehicles, energy storage systems and other fields. With the continuous improvement of the performance requirements for lithium batteries, the development of new battery materials has become more and more crucial. Boron trioxide(B2O3,boric oxide), as a material with unique physical and chemical properties, has shown great application potential in lithium battery substrates. With the deepening of research and continuous progress of technology, boron trioxide(B2O3,boric oxide) is expected to be more widely used in the field of lithium batteries. By optimizing the preparation process and formulation of the material, boron trioxide(B2O3,boric oxide) will make greater contributions to improv the performance of lithium batteries, reducing costs, and promoting the development of lithium battery technology. At the same time, the composite application of boron trioxide (B2O3,boric oxide)and other new materials will also become the focus of future research, and it is expected to develop a lithium battery material system with better performance to meet the growing energy demand.
