Abstract: A battery cell comprises a battery cell enclosure made of a non-metallic material. First battery terminals arranged in the battery cell enclosure. Second battery terminals arranged in the battery cell enclosure. Electrolyte is located between the first battery terminals and the second battery terminals. C conductive portions are arranged adjacent to an outer surface of the battery cell enclosure, where C is an integer greater than zero.

Abstract: A method is provided for pre-forming anode particles for use in lithium ion batteries. The pre-formed anode particles bear a solid electrolyte of a composition that cannot be formed in situ in the battery. The method includes providing a dispersion of anode precursor particles and an additive not found in the battery in a liquid electrolyte solution. Applying a voltage or current across the dispersion forms the solid electrolyte interphase, on the particles. These particles can be used in an electrode of a lithium ion battery.

Abstract: A quality control system in a battery manufacturing process includes two or more capacitive measurement apparatuses to obtain a capacitance measurement from two or more intermediate products generated during the battery manufacturing process. The system also includes processing circuitry to obtain the capacitive measurement from the two or more capacitive measurement apparatuses, to determine a characteristic of the corresponding intermediate product, and to control at least one process of the battery manufacturing process that produced at least one of the two or more intermediate products based on the characteristic.

Abstract: A method for forming a layered anode material includes contacting a precursor material and a first electrolyte. The precursor material is a layered ionic compound represented by MX2, where M is one of calcium and magnesium and X is one of silicon, germanium, and boron. The method further includes applying a first bias and/or current as the precursor material contacts the first electrolyte to remove cations from the precursor material to create a two-dimensional structure that defines the layered anode material. In certain variations, the method further includes contacting the two-dimensional structure and a second electrolyte and applying a second bias and/or current as the two-dimensional structure contacts the second electrolyte so as to cause lithium ions to move into interlayer spaces or voids created in the two-dimensional structure by the removal of the cations thereby forming the layered anode material.

Abstract: A method for detecting a contaminant in a vehicle coolant system during service includes contacting a chromophore impregnated strip and a heat transfer fluid sample, where the chromophore impregnated strip includes a complexing agent selected to form a complex with the contaminant that causes a color change in the chromophore impregnated strip and thereby indicates the presence of the contaminant in the heat transfer fluid sample.
