Sodium pyrophosphate new application in battery

Sodium pyrophosphate a new application has been found in battery production

The sodium pyrophosphate application in battery mainly focuses on the following aspects:
Sodium ion battery cathode material: Sodium pyrophosphate is used as a key raw material for preparing sodium ion battery cathode materials. For example, Na2FeP2O7 (sodium iron pyrophosphate) is a promising iron-based cathode material with a working voltage of 3V and a theoretical discharge specific capacity of 97 mAh · g-1
This material can generate good electrochemical activity and high volumetric energy density without the need for nanoscale or carbon coated electrodes
.
Improving battery performance: Adding an appropriate amount of sodium pyrophosphate to the electrolyte of the battery can significantly enhance its cycling stability and discharge efficiency. Sodium pyrophosphate has excellent chemical and thermal stability, which can maintain battery performance unaffected in high temperature environments and extend the service life of batteries
.
Dual guarantee of environmental protection and safety: Sodium pyrophosphate, as an environmentally friendly material, its application in battery manufacturing reduces environmental pollution and also lowers the safety risks of batteries under extreme conditions
.
Preparation method: The application of sodium pyrophosphate in the field of batteries involves multiple preparation methods. For example, a method for preparing high rate and long cycle sodium iron phosphate pyrophosphate material achieves uniform dispersion of the material at the molecular level through complexation and reduction methods. At the same time, a reducing agent is added to reduce trivalent iron to divalent iron before sintering, and carbon coating is added to improve the electrochemical performance of the material, especially the capacity and cycling performance at high rates
.
Modified material: By introducing sulfate ions and regulating the amount of iron defects, the voltage plateau is increased while the discharge capacity is increased, and the stability of the material is improved. This modified iron phosphate sodium positive electrode material can effectively improve the discharge capacity, energy density, and cycling stability of sodium ion batteries when applied
.
Compatible with existing production processes: The use of sodium pyrophosphate is also compatible with the existing production process of lithium iron phosphate, and the method is simple with good industrialization prospects
.
In summary, sodium pyrophosphate plays an important role in the field of battery production. It not only serves as a key raw material, but also helps to improve battery performance and safety. At the same time, it is environmentally friendly and has broad application prospects.
