Advanced paymentNano Tungsten Oxide Powder as Lithium Ion Battery Cathode Materials WO3 Nanoparticle
Good properties and application of nano tungsten trioxide powder(WO3 nanoparticle):
More and more attention has been paid to nano WO3 lithium-ion battery anode materials, and WO3 nano powder also exhibits good electrochemical performance. This is mainly due to the fact that WO3 is used as a negative electrode material, and its theoretical specific capacity is 693 mA hg-1, which is much higher than that of graphite, and its cost is lower. Moreover, compared with other transition metal oxides, WO3 has many advantages as a negative electrode material in lithium-ion batteries: tungsten is the highest valence state, with good stability and high safety performance; WO3 is a benign semiconductor with high conductivity, high dielectric constant; WO3 density (7.16gcm-3), high volume specific capacity.
