Three-electrode cell system for the study of reversible cathodes in rechargeable lithium batteries

A three-electrode cell system is described which incorporates a cell holder assembly, a lithium ribbon punch, an electrode insertion tool and a sealed container. The cell design is such that the current collectors for the lithium electrodes do not come into contact with the electrolyte. Use of the system enables cells for studying reversible cathodes to be reliably assembled in the glove box and then removed for extended cycle testing.
