Patent ID: 8241541

Claim:
A process for preparing a pre-mix positive electrode in transportable solid form for electrochemical cells, the process comprising the steps of: (a) in a mixing device, mixing together a polyether comprising between 1000 ppm and 10000 ppm of water, at least one solvent, a lithium salt and solid particles of electrochemically active material to form a mixture of polyether-salt-solid particles; (b) evaporating the at least one solvent present in the mixture of polyether-salt-solid particles to obtain a dried polyether-salt-solid particles mixture; (c) melting the dried polyether-salt-solid particles mixture through a melting and pumping device, thereafter cooling and hardening the melted polyether-salt-solid particles mixture and breaking down the hardened polyether-salt-solid particles mixture into a transportable solid shape selected from the group consisting of chunks, pucks, carrots, stripes, pellets, granules, powder, flakes and combinations thereof through a mechanical cutting device thereby forming transportable solids; and (d) mixing fumed silica which is compatible with the electrochemistry of electrochemical cells with the pre-mix positive electrode in transportable solid form resulting from step (c) to inhibit adhesion of the transportable solids during transport or storage.
