  • Publication number: 20240356068
    Abstract: Systems and methods are provided for a slurry for coating an electrode structure. In one example, a method may include dispersing, by mixing at one or both of a high shear and a low shear, a solid ionically conductive polymer material in at least a first portion of a solvent to form a suspension, then dispersing, by mixing at the one or both of the high shear and the low shear, one or more additives in the suspension, and then mixing, at the one or both of the high shear and the low shear, a second portion of the solvent with the suspension to form a slurry. As such, the slurry including the solid ionically conductive polymer material may be applied as a coating in a solid-state battery cell, which may reduce resistance to Li-ion transport and improve mechanical stability relative to a conventional solid-state battery cell.

  • Publication number: 20220359912
    Abstract: A coated hybrid electrode for a composite solid-state battery cell is disclosed. Systems and methods are further provided for forming an electrolyte coating including a solid ionically conductive polymer material in the coated hybrid electrode. In one example, the coated hybrid electrode can include an anode material coating, the solid polymer electrolyte coating, and a cathode material coating, such that the solid polymer electrolyte coating can function as a separator coating between the anode material coating and the cathode material coating, thus eliminating a need for a conventional battery separator. In some examples, a slurry-based coating process can be utilized for forming the solid polymer electrolyte coating. As such, the solid polymer electrolyte coating can be mechanically robust with uniform thickness. Further, a battery cell can be formed by utilizing a sub-assembly stacking technique to provide battery cell stiffness and increase precision and accuracy of coating.

  • Publication number: 20220069292
    Abstract: Methods and systems are provided for a blend of cathode active materials. In one example, the blend of cathode active materials provides a high power battery with low direct current resistance while improving lithium ion cell safety performance. Methods and systems are further provided for fabricating the cathode active material blend and a battery including the blend.
