Abstract
Official abstract text for this publication.
A novel conversion-type rechargeable battery is constructed, the battery using selenium as the cathode material. Preferably, the selenium is coated over the surface of the pores in a mesoporous ion collector such as carbon. A salt of zinc having an organic ion with polar function group is used with the battery, allowing the solvent of the battery to be either organic or aqueous.
First claim
Opening claim text (preview).
The invention claimed is: 1. A zinc-selenium battery consisting essentially of: a zinc anode; a cathode consisting essentially of selenium active material supported on an ordered mesopores carbon composite electron current collector; and an electrolyte solution consisting essentially of ethyl methyl carbonate and a Zn((CF 3 SO 2 ) 2 N) 2 .
