    摘要: This invention, in some variations, provides a separator for a lithium-sulfur battery, comprising a porous substrate that is permeable to lithium ions; and a lithium-ion-conducting metal oxide layer on the substrate, wherein the metal oxide layer includes deposits of sulfur that are intentionally introduced prior to battery operation. The deposits of sulfur may be derived from treatment of the metal oxide layer with one or more sulfur-containing precursors (e.g., lithium polysulfides) prior to operation of the lithium-sulfur battery. Other variations provide a method of charging a lithium-sulfur battery that includes the disclosed separator, the charging being accomplished by continuously applying a substantially constant voltage to the lithium-sulfur battery until the battery charging current is at or below a selected current.

    摘要: A thermomagnetic sensor includes a thermomagnetic probe that includes a ferromagnetic material having a temperature-dependent magnetic permeability characterized by a maximum magnetic permeability value at a temperature below a Curie temperature of the ferromagnetic material. The thermomagnetic sensor further includes an alternating magnetic field source to produce an alternating magnetic field in a vicinity of the thermomagnetic probe to facilitate a measurement of the temperature-dependent magnetic permeability as function of temperature remotely using a thermomagnetic effect. A predetermined relationship between the temperature-dependent magnetic permeability and temperature in a range between the maximum magnetic permeability value and the Curie temperature provides a measurement of a temperature local to the thermomagnetic probe. A battery-temperature measurement system includes the thermomagnetic probe in a battery, a magnetic field coil to apply the alternating magnetic field, and a magnetic permeability measurement apparatus to measure the temperature-dependent magnetic permeability.

    摘要: A dumbbell apparatus which is adapted with a series of weight plates, the number of which can be safely and reliably adjusted with a single simple motion. The apparatus comprises a cradle for storing and deploying the apparatus, weight plates, and a handle apparatus which has two spline bolts which support the weight plates and are used to simultaneously be adjusted by means of an adjusting pin which moves the spline members together through a motion transmitting gear. The apparatus may be further enhance with permanent weights and gripping options.

    摘要: This invention provides batteries with improved calendar and cycle lifetimes. A rechargeable battery comprises an additional electrode that includes active ions, such as lithium ions. Cell capacity of the battery can be increased by supplying these active ions to the anode or the cathode. In some variations, this invention provides a lithium-ion battery comprising an anode, a cathode, an electrolyte, and an additional lithium-containing electrode, wherein the additional lithium-containing electrode is capable of supplying lithium ions to the anode or the cathode in the presence of an electrical current.
