摘要： The present invention provides an ionic conductive battery that exhibits an electron conductivity via a micro-capacitor formed between battery electrodes, wherein the ionic conduction battery comprises a dipole micro-capacitor containing hydrogen peroxide and being formed between a cathode electrode made of copper or alloy thereof and an anode electrode made from a metal or an alloy that forms an electrode potential difference, the electrode potential of the anode electrode being more base than that of the cathode electrode, and said micro-capacitor forming a structure that exhibits a property via which electrons flow from the cathode electrode to the anode electrode. Said ionic conduction battery causes current amplification that resembles avalanche amplification.

摘要： A button battery, a manufacturing method thereof, and an electronic device are disclosed, the button battery includes a housing including a bottom cover on a side of a negative electrode sheet and a positive electrode cover on a side of a positive electrode sheet; the housing includes the positive electrode sheet, a separator, a carbon foil, and the negative electrode sheet stacked in sequence; the separator has an inverted U-shape, and both sides of the inverted U-shape are bent toward the positive electrode sheet; the button battery is filled with electrolyte. The button battery of the present application is provided with the carbon foil between the negative electrode sheet and the separator, the carbon foil can suppress a reaction of the negative electrode with electrolyte and positive electrode ions, thereby reducing the internal resistance of the button battery and the resistance of the negative electrode surface. Meanwhile, by arranging the carbon foil on the negative electrode surface, the button battery has a double-layer capacitance characteristic to shunt the current on the negative electrode surface, thereby greatly improving the performance of the button battery under high current discharge and the pulse performance at low temperature.

摘要： Disclosed is a flat lithium primary battery including a case, a positive electrode, a negative electrode, a separator, and a nonaqueous electrolyte, in which the positive electrode, the negative electrode, the separator, and the nonaqueous electrolyte are disposed in the case. The positive electrode includes: a positive electrode active material; and a fluorocarbon resin with swellability in the nonaqueous electrolyte. In the positive electrode, the fluorocarbon resin is present in particulate form. When, on the flat lithium primary battery having been put in an environment with a temperature of 25°C, a high temperature storage test to store the flat lithium primary battery in an environment with a temperature of 125°C for 100 hours is conducted, the ratio d2/d1 of a particle diameter d2 of the fluorocarbon resin after the high temperature storage test to a particle diameter d1 of the fluorocarbon resin before the high temperature storage test is 1.5 or higher and 3.1 or lower.

摘要： An apparatus for separating battery plates comprises a work surface for receiving a stack of battery plates, a displacement mechanism configured to shear the plates relative to each other and an alignment mechanism. The displacement mechanism may comprise opposing jaws comprising a projecting arrow head profile and a corresponding concave-shaped profile. Further disclosed is a further apparatus comprises a work surface for receiving a stack of battery plates that is moveable between a first position in which it is angled, and a second position in which it is substantially aligned, with respect to a horizontal plane, such that when the work surface moves between the first and second positions adjacent battery plates are displaced relative to each other, and an alignment mechanism for aligning the battery plates on the work surface. Further disclosed is a robot head arrangement for transferring stacks of battery plates comprising a plurality of grippers each comprising a pair of opposed gripping members and an actuator. Also disclosed is a pallet for the supply of battery plates having a surface provided with a ribbed profile.
