(JA) リチウムイオン二次電池および蓄電装置
Abstract:
(EN) Provided is a highly reliable lithium ion secondary cell in which increases in the temperature of the cell during short circuiting is suppressed. This lithium ion secondary cell has a cathode having a cathode mixture layer, an anode having an anode mixture layer, and an electrolyte, wherein the cathode mixture layer and/or the anode mixture layer contains a hydrogencarbonate represented by M1(HCO3)x, or contains a hydrogencarbonate represented by M2(HCO3)y and a compound represented by one of M1A(SO4)B and M1C(PO4)D (where M1 is a trivalent or greater metallic element; x is a value of 3 or greater corresponding to the valence of M1; M2 is a monovalent or divalent metallic element; y is a value of 1 or 2 corresponding to the valence of M2; A, B, C, and D are positive integers; A is a positive integer such that in B = AV/2 yields a minimum positive integer; C is a positive integer such that D = CV/3 yields a minimum positive integer; and V is the valence of the metallic element M1).
(FR) L'invention concerne un élément secondaire au lithium-ion très fiable dans lequel l'augmentation de la température de l'élément pendant un court-circuit est supprimée. Cet élément secondaire au lithium-ion comporte cathode ayant une couche de mélange de cathode, une anode ayant une couche de mélange d'anode, et un électrolyte, la couche de mélange de cathode et/ou la couche de mélange d'anode contenant un carbonate d'hydrogène représenté par M1(HCO3)x, ou contient un carbonate d'hydrogène représenté par M2(HCO3)y et un composé représenté par M1A(SO4)B ou M1C(PO4)D (où M1 est un élément métallique trivalent ou plus ; x est une valeur de 3 ou plus correspondant à la valence de M1 ; M2 est un élément métallique monovalent ou divalent ; y est une valeur de 1 ou 2 correspondant à la valence de M2 ; A, B, C et D étant des entiers positifs ; A est un entier positif de telle sorte que B = AV/2 donne un entier positif minimum ; C est un entier positif de telle sorte que D = CV/3 donne un entier positif minimum ; et V est la valence de l'élément métallique M1).
(JA) 短絡時に電池の温度上昇が抑制され信頼性の高いリチウムイオン二次電池を提供する。リチウムイオン二次電池は、正極合剤層を有する正極と、負極合剤層を有する負極と、電解液と、を有するリチウムイオン二次電池において、前記正極合剤層または前記負極合剤層の少なくともいずれか一方には、M1(HCOで表わされる炭酸水素塩が含まれるか、または、M2(HCOで表わされる炭酸水素塩とM1(SOおよびM1(POのいずれかで表わされる化合物とが含まれる(ただし、M1は3価以上の金属元素、xはM1の価数に相当する3以上の値、M2は1価または2価の金属元素、yはM2の価数に相当する1または2の値、A、B、CおよびDは正の整数であり、AはB=AV/2が最小の正の整数となるような正の整数、CはD=CV/3が最小の正の整数となるような正の整数、Vは金属元素M1の価数である)。
