摘要:
A lithium secondary battery includes a cathode which can be dischargeably charged with lithium ions, an anode made of lithium metal, a lithium alloy or any other anode material which can be releasably doped with lithium ions, an electrolyte which allows migration of lithium ions between both electrodes, and an endothermic substance which undergoes an endothermic reaction upon a temperature rise of the battery for preventing excessive heat generation. Typically, the endothermic substance is a metal carbonate such as magnesium carbonate, cobalt (II) carbonate, silver carbonate, cadmium carbonate or sodium hydrogencarbonate.

An electrolytic solution for a lithium secondary battery is provided, which comprises: an electrolyte; an organic solvent; and an additive, wherein the additive is an aromatic nitrogen-containing heterocyclic compound such as pyrazine, quinoxaline, indole, phenazine, phthalazine, pyrimidine, or a mixture thereof.
摘要:
A lithium secondary battery includes a cathode which can be dischargeably charged with lithium ions, an anode made of lithium metal, a lithium alloy or any other anode material which can be releasably doped with lithium ions, and an electrolyte which allows migration of lithium ions between both electrodes. The cathode contains a halogen compound which releases halogen atoms, halogen ions or a reactive halogen-containing substance for reacting with the anode, thereby deactivating the anode to prevent excessive heat generation before oxygen released from the cathode due to a temperature rise reacts with the anode.
摘要:
A lithium secondary battery comprises a cathode 1 capable of charging and discharging lithium ions, an anode 2 formed from a material which can be doped and de-doped with lithium ions, lithium metal, or the like, and an electrolyte that allows the movement of lithium ions. The anode 2 contains an imide compound represented by the chemical formula below. In the chemical formula above, Z is an optionally substituted —(CH2)n— (where n is an integer from 2 to 7), 1,2-cyclohexylene or 1,2-phenylene; X is a hydrogen atom, or an optionally substituted alkyl group, aralkylcarbonyl group, alkylcarbonyl group, alkoxycarbonyl group, aralkyloxycarbonyl group, or imidyloxycarbonyl group.

A fuel cell includes an electric power generation part; the electric power generation part including an air electrode to which oxygen gas is supplied, a fuel electrode to which fuel gas is supplied, and a solid electrolyte layer having a proton conductivity and put between the air electrode and fuel electrode; a fuel storage part storing a liquid fuel; a liquid fuel vaporization film made of non-porous material and configured to vaporize the liquid fuel so as to supply fuel gas to the fuel electrode; and a gas fuel supply speed control plate provided between the liquid fuel vaporization film and the fuel electrode and configured to control a supply speed of the fuel gas to the fuel electrode. The gas fuel supply speed control plate includes a plurality of openings piercing between the liquid fuel vaporization film and the fuel electrode.
摘要:
In the present invention, a material having a structure represented by formula (1) or (2) (wherein W equals N or C) is used as a solid electrolyte for a fuel cell. An electrolyte membrane having a small fuel crossover and a fuel cell having excellent ion conductivity and service capacity are obtained.
摘要:
A housing made of a magnesium material is colored by a non-painting process. In this process, an anode oxide film is grown on the surface of the housing by subjecting the housing to anodization. The anode oxide film is colored without a paint being applied to the surface of the film.
