Battery components employing a silicate binder
| DWPI Title: Battery component e.g. fuel cell electrodes and separators comprises a current collector in contact with an electrode layer and separator layer, where both the electrode layer and separator layer are made of glassy silicate binder material |
| Abstract: A battery component structure employing inorganic-silicate binders. In some embodiments, casting or coating of components may be performed using aqueous slurries of silicates and electrode materials or separator materials. |
| Use: As battery components (Claimed) particularly as thermal battery components; in fuel cell electrodes and separators; in cathodes and separators of other non-aqueous battery systems or electrochemical capacitor systems that utilize organic electrolytes, non-aqueous inorganic electrolytes, or ionic liquid electrolytes. |
| Advantage: The battery components can be made by eliminating excess active materials thus resulting in thinner components than components formed by conventional techniques, such as pellet compression. The battery component provides batteries with significant improvements in energy density and power density. The silicate binders employed enable the use of coating, casting and printing technology to fabricate thin conformally bonded electrodes and electrode/separator components. |
| Novelty: A battery component structure comprises: a current collector (10) in contact with an electrode layer (11) comprising an electrode material (M1) intermixed with a glassy silicate binder material; and a separator layer (14) comprising (M1) and in contact with a surface of the electrode layer that is not a surface which is in contact with the current collector. The glassy silicate binder material serves as a binder to bind the electrode material. The electrode separator material comprises an electronic insulator. |
