Abstract
A process for forming an electrode involves mixing or homogenizing one or more electrode components in a 'fugitive carrier'. This mixture is then frozen by dropping the temperature to a level below which the fugitive carrier freezes. This locks the well-mixed electrode components in place in a solid matrix to form an electrode precursor. Thereafter, the fugitive carrier is sublimated from the electrode precursor to form an electrode in which the components are substantially unsegregated.
