Zusammenfassung:	An active material suitable for use in lithium cells comprises lithium titanate having a surface and a material disposed on the surface is provided. The material is non-reactive with an electrolyte within a range of potential vs. lithium of from 0 V to 4 V. A variety of lithium cells including lithium titanate are also provided. The lithium titanate is typically of the general formula: Li4Ti5O12-x, wherein x is greater than 0. Further, a cell module is provided. The cell module comprises a plurality of lithium cells each having a soft outer packaging and assembled in an environment where water content in the environment is controlled.
