Abstract: Embodiments described herein relate generally to electrochemical cells having high rate capability, and more particularly to devices, systems and methods of producing high capacity and high rate capability batteries having relatively thick semi-solid electrodes. In some embodiments, an electrochemical cell includes an anode and a semi-solid cathode. The semi-solid cathode includes a suspension of an active material of about 35% to about 75% by volume of an active material and about 0.5% to about 8% by volume of a conductive material in a non-aqueous liquid electrolyte. An ion-permeable membrane is disposed between the anode and the semi-solid cathode. The semi-solid cathode has a thickness of about 250 μm to about 2,000 μm, and the electrochemical cell has an area specific capacity of at least about 7 mAh/cm2 at a C-rate of C/4. In some embodiments, the semi-solid cathode slurry has a mixing index of at least about 0.9.

Abstract: Embodiments described herein relate generally to electrochemical cells having porous semi-solid electrodes and in particular, semi-solid electrodes that include electrolyte filled meso-pores such that the semi-solid electrodes have higher electronic conductivity. In some embodiments, a method of preparing a porous semi-solid electrode includes combining an active material with an electrolyte to form an intermediate material, the electrolyte including a liquid component and a pore former. A conductive material is combined with the intermediate material to form a semi-solid electrode material. The pore former is then caused to liquefy to form a porous semi-solid electrode. In some embodiments, the pore former is maintained at a temperature below a dissolution temperature and/or a melting temperature of the pore former prior to causing the pore former to liquefy. In some embodiments, the pore former can be ethylene carbonate (“EC”).

Abstract: Embodiments described herein generally relate to spacers for applying a preload on one or more electrochemical cells disposed in a battery pack. In some embodiments, a battery pack can include a plurality of electrochemical cells. A spacer is disposed between each of the plurality of electrochemical cells such the spacer is centrally located with respect to the mid-point of adjacent electrochemical cells. The spacer can be sized and shaped to contact in the range of about 2% to about 50% of a surface area of each adjacent electrochemical cell such that the spacer exerts a preload on a central portion of the electrochemical cell.
