摘要： Prelithiation methods and fast charging lithium ion cell are provided, which combine high energy density and high power density. Several structural and chemical modifications are disclosed to enable combination of features that achieve both goals simultaneously in fast charging cells having long cycling lifetime. The cells have anodes with high content of Si, Ge and/or Sn as principal anode material, and cathodes providing a relatively low C/A ratio, with the anodes being prelithiated to have a high lithium content, provided by a prelithiation algorithm. Disclosed algorithms determine lithium content achieved through prelithiation by optimizing the electrolyte to increase cycling lifetime, adjusting energy density with respect to other cell parameters, and possibly reducing the C/A ratio to maintain the required cycling lifetime.

摘要： The present invention relates to an electrolytic copper foil for a secondary battery, and a method of producing the same. The electrolytic copper foil for a secondary battery exhibits a little change in a physical property caused by a difference in a crosshead speed when tensile strength and an elongation percentage of the electrolytic copper foil are measured, thereby achieving excellent charging and discharging characteristics of a battery and preventing exfoliation of an active material. The electrolytic copper foil for a secondary battery is produced from a plating solution containing Total Organic Carbon (TOC), cobalt, and iron by using a drum, in which a ratio of the TOC to the cobalt and the iron contained in the electrolytic copper foil follows Formula 1 below. TOC/(cobalt+iron)=1.3 to 1.5 [Formula 1]

摘要： The present application provides a self-powered drug-delivery device. The device includes a chamber having a wall. The chamber contains a fluid and is in connection with an administration means. The device also includes a displacement-generating battery cell. The device further includes an electrically-controlled battery unit, which includes the displacement-generating battery cell coupled to the chamber by a coupling means. The displacement-generating battery cell includes an element that changes shape as a result of charge or discharge of the battery cell so as to cause a displacement within the battery unit. The arrangement of the battery unit, the coupling means, the wall, the chamber, and the administration means is such that the displacement derived from the battery unit is conveyed by the coupling means to cause displacement of the wall of the chamber such that the fluid is expelled from the chamber to force a drug towards the administration means.

摘要： The present invention provides an all-solid-state secondary battery and a method for producing the same, wherein it is possible to prevent the collapse of a laminate due to a shearing force occurring in the peripheral portion of the laminate when the laminate is pressed, and the occurrence of an internal short circuit can be prevented. The all-solid-state secondary battery includes a laminate and a plate-shaped insulating member both arranged between the positive electrode collector and the negative electrode collector. The laminate includes a positive electrode layer, a solid electrolyte layer, and a negative electrode layer. The plate-shaped insulating member is arranged around the laminate and contacted at least with the solid electrolyte layer to electrically insulate the positive electrode layer from the negative electrode layer. In the insulating member, a contact inner edge portion contacted with the laminate is thicker than a plate-shaped portion on the outer side.

摘要： In certain embodiments, the invention relates to an electrochemical device having a liquid lubricant impregnated surface. At least a portion of the interior surface of the electrochemical device includes a portion that includes a plurality of solid features disposed therein. The plurality of solid features define a plurality of regions therebetween. A lubricant is disposed in the plurality of regions which retain the liquid lubricant in the plurality of regions during operation of the device. An electroactive phase comes in contact with at least the portion of the interior surface. The liquid lubricant impregnated surface introduces a slip at the surface when the electroactive phase flows along the surface. The electroactive phase may be a yield stress fluid.

摘要： A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%. The set of electrode constraints further includes a secondary constraint system having first and second secondary growth constraints connected by at least one secondary connecting member, wherein the secondary constraint system at least partially restrains growth of the electrode assembly in a second direction upon cycling of the secondary battery.
