  • Publication number: 20220302438
    Abstract: The present disclosure relates generally to an electrode produced with a non-toxic solvent, resulting in a homogeneous mixture with uniform distributions of a conductive additive and a binder. Electrodes produced according to the present disclosure feature narrow binder particle size distribution, which distinguishes such electrodes from typical electrodes produced via a N-Methyl-Pyrrolidone (NMP) process. The resulting microstructure promotes the flow of current through the electrode and has an improved cycling stability due, in part, to the binder's and the conductive additive's ability to bind with the active material particles used in the fabrication of the electrode.

  • Publication number: 20220231375
    Abstract: Present embodiments disclosure discloses a battery module, which includes a plurality of battery cells, a busbar, a cover member, an insulator member positioned between the plurality of battery cells, and a casing element enclosing all the above. The cover member positioned above the busbar. The cover member includes an elongated body defining a first major surface and a second major surface, where the second major surface is defined with a plurality of grooves. The cover member also includes a plurality of dimples are defined along at least one of the first major surface and the second major surface. Further, at least one dimple of the plurality of dimples melt and form an aperture when at least one battery cell of the battery module undergoes a thermal runaway, to fluidly connect the first major surface with the plurality of grooves.

  • Patent number: 10153482
    Abstract: The present invention relates to a method for manufacturing slurry for coating of electrodes for use in lithium ion batteries, wherein the method comprises mixing active materials with a binder into a binder solution, and adding an organic carbonate to the binder solution to generate the slurry. The present invention also relates to a method for manufacturing electrodes for a lithium battery cell, wherein the method comprises mixing active materials with a binder into a binder solution, adding an organic carbonate to the binder solution to generate slurry, wherein the above adding step is carried out at temperature above melting temperature of the organic carbonate, coating electrode material with the slurry, drying the coating on the electrode material by drying the organic carbonate, and surface treatment of the slurry so that the electrode is prepared for use in a lithium ion battery cell.
