Abstract: Lithium-ion batteries (LIBs) which include a metal phosphate coating material reactive (scavenging) or stable with cathode materials, HF, LiF, PF5?, and LiOH. The metal phosphates may be applied on the cathode material of LIBs.

Abstract: Systems and methods for mixing are disclosed. A system for mixing can include a mixer vessel that defines a chamber. The system can include a first mixing blade to cause a first rotational movement to mix a material within the chamber. The system can include a second mixing blade to cause a second rotational movement to mix the material within the chamber of the mixer vessel. The system can include a mixing element to cause a third rotational movement to mix the material within the chamber of the mixer vessel. The system can include the first mixing blade to cause the first rotational movement independent from at least one of the second rotational movement and the third rotational movement.

Abstract: A cathode active material includes a bulk nickel-rich cathode active material having a lithium metal oxide coating on a surface of the bulk nickel-rich cathode active material, wherein the lithium metal oxide coating exhibits one or more of the following: a greater PF5? score when normalized to that of LiAlO2 at 100%; a greater HF score when normalized to that of LiAlO2 at 100%; or in absolute terms, an enthalpy of reaction value that is less than 0.351.

Abstract: A blended lithium-ion electrode for an electric vehicle and methods of manufacturing the electrode are disclosed. The blended lithium-ion electrode includes a first mixture of a lithium metal oxide comprised of LiXO2, wherein X is selected from the group consisting of nickel, cobalt, manganese, aluminum, iron, or mixtures thereof; and a second mixture of a lithium iron phosphate comprised of LiYPO4, wherein Y is selected from the group consisting of iron, manganese, cobalt, nickel, aluminum, titanate, or mixtures thereof. In further embodiments, the blended lithium-ion electrode includes graphene sheets to provide structure, electrochemical stabilizer, and electronic conductivity enhancer.

Abstract: An electrochemical cell comprises a can comprising a cylindrical side wall extending from a closed end wall. The closed end wall comprises a protrusion. The protrusion has a protrusion cavity therein. A pre-formed pellet of a first electrode material is disposed in the protrusion cavity. The electrochemical cell may further comprise a separator defining an inner cavity and separating the inner cavity from an outer cavity. The outer cavity is defined by the can and the separator. The electrochemical cell may further comprise a first electrode material disposed in the outer cavity; and a second electrode material disposed in the inner cavity.

Abstract: Described herein are various embodiments for using a touch screen with polar coordinates thereon to control the movements of seats in a vehicle. An exemplary method of adjusting seats in a vehicle includes the operations of detecting a touching on a circumference of a circular graphic on a touch screen in a vehicle, wherein the circular graphic is in a polar coordinate system on the touch screen; and determining a polar angle formed by a point of the touching on the circumference of the circular graphic in the polar coordinate system. The method further includes the operations of calculating a first value and a second value associated with the polar angle, each of the first value and the second value representing a movement range in a direction; and adjusting a vehicle seat based on the first value and the second value, including simultaneously moving the vehicle seat in in a first direction indicated by the first value and a second direction indicated by the second value.

Abstract: A separator for a bobbin-style electrochemical cell is inserted into an interior opening within a ring-shaped cathode in an electrochemical cell can. An expansion force is then applied to an interior surface of the separator to press the separator against the interior walls of the cathode. A tool may then remove various creases and/or wrinkles in the separator and/or may then heat seal at least a portion of the tubular walls of the separator to minimize the void space between the separator and active material (e.g., cathode and/or anode) within the electrochemical cell.

Abstract: A separator for a bobbin-style electrochemical cell is inserted into an interior opening within a ring-shaped cathode in an electrochemical cell can. An expansion force is then applied to an interior surface of the separator to press the separator against the interior walls of the cathode. A tool may then remove various creases and/or wrinkles in the separator and/or may then heat seal at least a portion of the tubular walls of the separator to minimize the void space between the separator and active material (e.g., cathode and/or anode) within the electrochemical cell.
