Abstract
The invention provides a pre-mix of positive electrode material in transportable solid form comprising polymer and solid particles of electrochemically active material and/or electronically conductive additives and a process for preparing a pre-mix positive electrode in transportable solid form. The pre-mix positive electrode material may also comprise an alkali metal salt either dissolved or dispersed in the mixture. The invention also provides making a cathode film from the transportable solid pre-mix of positive electrode material.
