摘要： An alkaline dry cell includes a positive electrode; a negative electrode; a separator disposed between the positive electrode and the negative electrode; and an electrolytic solution contained in the positive electrode, the negative electrode, and the separator, wherein the electrolytic solution contains an alkaline aqueous solution. The negative electrode contains an additive and a negative electrode active material containing zinc; and the additive contains at least one selected from the group consisting of benzoic acid, phthalic acid, isophthalic acid, and salts of the foregoing. The amount of the negative electrode active material contained in the negative electrode is from 176 to 221 parts by mass relative to 100 parts by mass of water contained in the electrolytic solution. The amount of the additive contained in the negative electrode is from 0.1 to 1.0 part by mass relative to 100 parts by mass of the negative electrode active material.

摘要： The system of the present invention includes a conductive element, an electronic component, and a partial power source in the form of dissimilar materials. Upon contact with a conducting fluid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature. The system can also measure the conditions of the environment surrounding the system.

摘要： An alkaline dry cell includes a bottomed cylindrical cell case, a positive electrode packed in the cell case and is made of a stack of n pieces of hollow cylindrical pellets, a negative electrode disposed in a hollow portion of the pellets, a separator interposed between the positive electrode and the negative electrode, and an alkaline electrolytic solution. A thickness of a body portion of the cell case is 0.08 to 0.16 mm. “n” is an integer of 3 or more. An average density dm of manganese dioxide in the n pellets is 2.80 to 3.00 g/cm3. A density of manganese dioxide of at least one pellet positioned in a middle portion in a height direction of the stack is 2.75 g/cm3 or less.

摘要： An apparatus including a first electrode including a substantially homogeneous mixture of graphene oxide and a proton conductor; a second electrode including reduced graphene oxide; and spaced-apart charge collectors for the respective first and second electrodes, wherein the first and second electrodes extend from their respective charge collectors towards one another to form a junction at an interface there between, and wherein the substantially homogeneous mixture of the first electrode is configured to be sufficiently hydrophobic to prevent intermixing of the homogeneous mixture with the reduced graphene oxide of the second electrode in proximity to one or both of the respective charge collectors to prevent short circuiting of the spaced-apart charge collectors.

摘要： In some examples, a primary battery comprising a cathode comprising at least one active material and at least one of a metal oxide and metal fluoride, wherein the active material exhibits a first discharge capacity and the at least one of metal oxide and metal fluoride exhibits a second discharge capacity at a voltage lower than the first discharge capacity; an anode comprising a metal as an electron source; and an electrolyte between the cathode and anode. The metal reacts with the electrolyte below a third discharge capacity at a voltage lower than the second discharge capacity to form a gas, where the metal reacts with the active material at the first discharge capacity, and, following the consumption of the active material of the cathode, the metal reacts with the at least one of metal oxide and metal fluoride of the cathode prior to reacting with the electrolyte below the third discharge capacity.
