Abstract
Pressed material such as anodes are described and formed from oxygen reduced oxide powders using additives, such as binders and/or lubricants. Methods to form the pressed material are also described, such as with the use of atomizing, spray drying, fluid bed processing, microencapsulation, and/or coacervation.
Claims27
A method of forming an anode comprising the steps of pressing a mixture comprising oxygen reduced niobium oxide powder and at least one binder or lubricant or both to form a pressed anode, wherein said mixture is prepared by coating said oxygen reduced niobium oxide powder with said binder and/or lubricant.
A method of forming an anode comprising the steps of pressing a mixture comprising oxygen reduced valve metal oxide powder and at least one binder or lubricant or both to form a pressed anode, wherein said mixture is prepared by coating said oxygen reduced valve metal oxide powder with said binder and/or lubricant.
A method of forming an agglomerated product comprising the steps of agglomerating a mixture comprising an oxygen reduced valve metal oxide powder and at least one additive to form an agglomerated product, wherein said mixture is prepared by coating said oxygen reduced valve metal oxide powder with said additive.
