Abstract
Official abstract text for this publication.
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, a semi-solid cathode that includes a suspension of an active material and a conductive material in a liquid electrolyte, and an ion permeable membrane disposed between the anode and the cathode. The semi-solid cathode has a thickness in the range of about 250 μm-2,500 μm, and the electrochemical cell has an area specific capacity of at least 5 mAh/cm 2 at a C-rate of C/2.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrochemical cell, comprising: an anode; a semi-solid cathode including a suspension of about 35% to about 75% by volume of an active material and about 1% to about 8% by volume of a conductive material in a non-aqueous liquid electrolyte; and an ion-permeable membrane disposed between the anode and the semi-solid cathode, wherein, the semi-solid cathode has a thickness in the range of about 250 μm to about 2,000 μm, wherein the electroch…
