Electrochemical slurry compositions and methods for preparing the same

摘要

Embodiments described herein generally relate to semi-solid suspensions, and more particularly to systems and methods for preparing semi-solid suspensions for use as electrodes in electrochemical devices such as, for example batteries. In some embodiments, a method for preparing a semi-solid electrode includes combining a quantity of an active material with a quantity of an electrolyte to form an intermediate material. The intermediate material is then combined with a conductive additive to form an electrode material. The electrode material is mixed to form a suspension having a mixing index of at least about 0.80 and is then formed into a semi-solid electrode.

1. A method of preparing a semi-solid electrode, the method comprising:
combining a quantity of an active material with a quantity of an electrolyte and a conductive additive to form an electrode material; mixing the electrode material to form a suspension having a mixing index of at least about 0.80; controlling a temperature of the electrode material during mixing to control evaporation of the electrolyte therefrom; forming the electrode material into a semi-solid electrode; forming a second electrode; and forming an electrochemical cell by combining the semi-solid electrode and the second electrode.
