Abstract
A semi-solid electrode includes a first porous substrate and a second porous substrate stacked together to form a current collector, and a semi-solid electrode material embedded in the current collector. The semi-solid electrode material includes a suspension of an active material and a conductive material disposed in a non-aqueous liquid electrolyte. The porous substrates are at least partially disposed within the suspension such that the suspension substantially encapsulates the porous substrates. Each porous substrate in the current collector defines a pitch, and the two pitches of the two porous substrates in the current collector can be shifted with respect to each other by 30% to 70% of the pitch so as to reduce polarization effect.
