The physical form of the powder is that of sintered agglomerates of  nominal 100 nanometer primary crystallites.   Agglomerates are nominally 10 microns in diameter with a D99 of less than 40 microns and minimal fines (D1 ~ 0.5 microns).   The integrity of the sintered agglomerates is maintained under the most aggressive calendering pressures and thinnest electrode coatings.

Electrochemical Performance

 

Coin cell testing of the Altairnano Lithium Titanate powder shows typical specific discharge capacity of 160mAh/g with maximum up to 170mAh/g.  Coin cell preparation is typical industry standard practice.  However the charge/discharge rate is tested at 1C because of the inherently fast rate of this Altairnano product.

Packaging

 

Altairnano  lithium titanate powder is available in aluminum foil packaging which is then protected in a sealed polyethylene container.  Each package contains 15 kg of the electrode material.  A water vapor barrier coating on the aluminum packaging insures that the low moisture content  ( ≤ 500 ppm H2O guaranteed,  215 ppm H2O typical ) of the material is maintained.
