発明の名称 (英語) MAGNESIUM SECONDARY BATTERY AND NEGATIVE ELECTRODE WITH INORGANIC MATERIAL FOR MAGNESIUM SECONDARY BATTERIES NEW
発明の概要(英語) A magnesium secondary battery which is provided with: a negative electrode; and an inorganic material, at least a part of which is in contact with the surface of the negative electrode, and which is composed of at least one of aluminum oxide and silicon oxide.
従来技術、競合技術の概要(英語) BACKGROUND ART
A high energy density lithium ion secondary battery (the product of the operating voltage and storage capacity) responsive to, a mobile phone, a small apparatus such as a smart phone, a hybrid car, electric car or the like as a power source such as the size of the device occupy the major status.However, the lithium-ion battery, the heating and firing conditions used by the risk, there is a fear of overcharge of the lithium precipitation by, approaching a theoretical energy density, the lithium source, the high cost of the transition metal used for electrode or the like, such as a large problem.Therefore, instead of the lithium secondary battery using magnesium in the magnesium has been proposed.
Standard electrode potential than the magnesium metal, and has a large capacity so that the ions 2.Therefore, a high energy density, and, an electrode material stable in the atmosphere.In addition, the resource is abundant magnesium from near the ground surface, the secondary battery using metal magnesium secondary battery is inexpensive and can be expected.As the magnesium secondary battery, for example, magnesium cations reversibly holding and releasing the positive electrode, the positive electrode and disposed opposite via a separator, a negative electrode active material and a negative electrode including magnesium metal or magnesium alloy, the electrolyte has been proposed that is provided (for example, see Patent Document 1).Patent Document 1 is further, the electrolyte, and magnesium cations, divalent anion 1, represented by the formula (I) (glyme compound) and a polyether compound containing solution has been described. (CH2CH2O) N-R2 R1-O(I) (in the formula, R1 and R2 each independently represents a substituent having carbon atoms which may contain 1-12 hydrocarbon group, n is an integer of 1-8) also, in non-patent document 1, glyme compound and the (symmetric glycol ether compound), the ionic liquid, and magnesium cations in the electrolyte are described.
