Sodium Titanate Nanotubes Used in Lithium-ion Battery Anode Material 

Spec: outer diameter: 10-15nm, inner diameter: 3-5nm, length: >1um, SSA: 300M2/G

In recent years, lithium ion batteries are widely used in mobile electronic devices of energy, quickly occupied the high-performance rechargeable battery market, with the development of the motor car and the hybrid locomotive, a growing need to have a high energy density and high discharge \ charging rate and long-life rechargeable lithium-ion battery. Now widely proven lithium ion battery charger, limit the rate of power generation is mainly composed of Li + solid-state diffusion in the electrode material caused slower. As the nano-structural materials of lithium ion diffusion distance can be reduced in solids, so people began working to develop lithium-ion battery electrode materials nanostructures. In addition, one-dimensional electrode structure for a lithium ion battery material exhibits excellent rate performance, because the Li + diffusion distance is limited to be within a range less than several tens of nanometers, is significantly smaller than the electrode powders. Due to the special layered structure facilitates lithium ion intercalation and deintercalation, so sodium titanate nanotubes in recent years begun to attract attention. Li et titanate nanotubes were added to the lithium-ion battery anode material, it showed great ability to embed lithium, high discharge, charging performance and excellent cycle stability.
