The present disclosure relates to improved LMO composition suitable for use as cathode material in rechargeable lithium ion batteries. The LMO composition may be doped with an additional metal or undoped. The LMO composition carries a surface treatment of LiF that protects the LMO from acid degradation. Cathodes prepared from the improved LMO have improved fade characteristics.

Lithium manganese oxide compositions

Disclosed herein is an improved cathode material prepared from high purity electrolytic manganese dioxide. Also disclosed is a method for preparing high purity MnOand converting MnOparticles to MnO.

Method for preparing electrolytic manganese dioxide

The present disclosure relates to the hydrostatic testing of pipelines and to purification of waste water from such testing. More specifically, there is provided a method of hydrostatically pressure testing a natural gas pipeline using water. The waste water, which is contaminated with hydrocarbons, is subsequently treated by contacting it with manganese dioxide so that the hydrocarbons are broken down into carbon dioxide and water.
