Nano tungsten trioxide can be used as the positive electrode material of sodium ion battery (Na-ion battery). Sodium-ion batteries are an emerging rechargeable battery technology that works similarly to lithium-ion batteries, but uses sodium ions as ions to store and release charge.
Nano tungsten trioxide as anode material for sodium ion battery has the following characteristics:
high capacity
Nano tungsten trioxide has a higher capacity and can store and release more sodium ions. This means that the nano-tungsten trioxide cathode material can provide more charge during the charging and discharging process.
good cycle performance
Nano-tungsten trioxide cathode materials usually exhibit good cycle performance, that is, they can maintain relatively stable capacity and electrochemical performance after multiple charge-discharge cycles.
good structural stability
Nano-tungsten trioxide has good structural stability, and can maintain the stability of its lattice structure during the insertion/extraction of sodium ions, thereby realizing long-term cyclic use.
Regulatory
By controlling the parameters such as size, morphology and structure of nano-tungsten trioxide, its electrochemical performance can be adjusted to meet the needs of sodium-ion batteries and optimize its battery performance.
The research on nano-tungsten trioxide as cathode material for sodium-ion batteries is still in the development stage. In practical application, further research and improvement of its performance are needed to improve the performance in terms of energy density, cycle life, and safety, so as to promote the development of Na-ion battery technology.
