BATTERIES

The sodium and lithium ion-conducting ceramic electrolyte membranes based on our proprietary high conductivity NaSICON, LiSICON, Garnet and β" –alumina compositions facilitate dendrite free operation of sodium and lithium metal anodes in ambient as well as high temperature organic and molten-salt catholyte batteries.


Ceramatec’s membranes are based on proprietary NaSICON composition can be utilized as a separator in solid sodium and molten sodium batteries in combination with a variety of cathodes.

We have demonstrated practical application and performance of our membranes in ambient, intermediate & high temperature solid/molten sodium battery systems including Na-NiCl2 (ZEBRA), Na-Iodine (Na-Halogen), Na-Air, Na-Sulfur and Na-Na Ion intercalation cathode.

Moderate temperature sodium battery.

Ceramic solid electrolyte membranes based on LiSICON, Garnet, & Li-β" –alumina compositions are being developed for next generation lithium metal batteries.

The developed membranes are metal dendrite resistant and chemically stable and can be applied for all-solid-state and hybrid Li metal anode – liquid catholyte batteries including Li-Air, Li-S and Li-intercalation cathode batteries.

Alkali metal seawater battery.

Application of Ceramatec's high conductivity membranes to low-cost aqueous anode and cathode batteries can further improve their cycle life and efficiency.

The solid-electrolyte membrane allows distinct aqueous formulations of anode and cathode to be used in both stagnant and flow batteries while allowing only the alkali ion transfer between the electrodes. This separation of electrode compartments allow novel battery chemistries not possible with microporous separators.
