摘要： The present disclosure provides a method for forming a layered anode material. The method 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 so as 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 include 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.

摘要： A battery with passive fire suppression capabilities includes a housing, a battery cell stack disposed within an interior of the housing, and a fire suppression material disposed within the interior of the housing. The battery cell stack includes a plurality of battery cells, with each of the plurality of battery cells including a nonaqueous electrolyte. When the fire suppression material is exposed to the nonaqueous electrolyte, the fire suppression material is configured to retain the nonaqueous electrolyte within the interior of the housing.

摘要： A battery system includes a battery housing having an interior compartment. A battery pack, including a plurality of battery cells, is in the interior compartment of the housing. A vessel defines an interior chamber and includes an air inlet, an oxygen discharge port, and an inert gas discharge port each in communication with the interior chamber. An oxygen separation material is in the chamber and is configured to separate oxygen from air supplied through the air inlet and to direct the oxygen to the oxygen discharge port. The oxygen separation material is further configured to direct remaining oxygen deficient air to the inert gas discharge port. The inert gas discharge port in communication with the interior compartment of the battery housing.

摘要： A method for extracting lithium from lithium-based materials to be recycled using an electrochemical reactor includes applying a voltage to a current collector at least partially disposed in an electrolyte carried by the electrochemical reactor, where the lithium-based materials including lithium to be recovered is disposed in the electrolyte and lithium ions move from the lithium-based material towards the current collector upon application of the voltage. In certain variations, the method may also include, prior to the application of the voltage, applying a current to the current collector.

摘要： A method for forming an electroactive material includes sourcing a current or voltage to an electrochemical reactor that includes a cation source, an electrolyte mixture, and an electroactive material precursor in contact with one another, where the current or voltage serves to ionize and form cations at the cation source that react with the electroactive material precursor in the electrolyte mixture to form the electroactive material. The method may include one or more filtering steps, one or more rinsing steps, or a combination of one or more filtering steps and one or more rinsing steps to collect the electroactive material from the electrolyte.

摘要： A vehicle coolant system includes a pipe configured to facilitate a flow of vehicle coolant through the pipe, a light source configured to transmit at least one wavelength of light through the vehicle coolant, and a signal detector configured to receive at least one wavelength of light transmitted through the vehicle coolant, and to generate a signal intensity value corresponding to a measured intensity of the at least one wavelength of light received at the signal detector. A controller is configured to receive the signal intensity value from the signal detector, identify a coolant contamination threshold value corresponding to the vehicle coolant, compare the signal intensity value received from the signal detector to the coolant contamination threshold value, and initiate a vehicle coolant remedial action according to a result of comparing the signal intensity value received from the signal detector to the coolant contamination threshold value.
