Title (EN) NONAQUEOUS ELECTROLYTE BATTERY AND BATTERY PACK
(FR) BATTERIE À ÉLECTROLYTE NON AQUEUX ET BLOC-BATTERIE
(JA) 非水電解質電池及び電池パック
Abstract:
(EN) One embodiment of the present invention provides a nonaqueous electrolyte battery. This nonaqueous electrolyte battery comprises a negative electrode, a positive electrode and a nonaqueous electrolyte. The negative electrode contains a negative electrode active material having a lithium adsorption/desorption potential of 0.8 V (vs. Li/Li+) or more. The positive electrode contains a positive electrode active material represented by LiMn1-x-yFexAyPO4 (wherein 0 < x ≤ 0.3, 0 ≤ y ≤ 0.1, and A represents at least one element selected from the group consisting of Mg, Ca, Al, Ti, Zn and Zr) and a substance that is capable of adsorbing lithium at a potential of 3.3 V (vs. Li/Li+) or less.
(FR) Un mode de réalisation de la présente invention pourvoit à une batterie à électrolyte non aqueux. Cette batterie à électrolyte non aqueux comprend une électrode négative, une électrode positive et un électrolyte non aqueux. L'électrode négative contient un matériau actif d'électrode négative présentant un potentiel d'adsorption/désorption du lithium supérieur ou égal à 0,8 V (vs Li/Li+). L'électrode positive contient un matériau actif d'électrode positive représenté par LiMn1-x-yFexAyPO4 (dans laquelle 0 < x ≤ 0,3, 0 ≤ y ≤ 0,1, et A représente au moins un élément choisi dans le groupe constitué par Mg, Ca, Al, Ti, Zn et Zr) et une substance qui est susceptible d'adsorber le lithium à un potentiel inférieur ou égal à 3,3 V (vs Li/Li+).
(JA) 実施形態によると、非水電解質電池が提供される。この非水電解質電池は、負極と、正極と、非水電解質とを含む。負極は、リチウム吸蔵放出電位が0.8V(vs. Li/Li+)以上である負極活物質を含む。正極は、LiMn1-x-yFexyPO4(式中、0<x≦0.3及び0≦y≦0.1であり、Aは、Mg、Ca、Al、Ti、Zn及びZrからなる群より選択される少なくとも1種である)で表される正極活物質と、3.3V(vs. Li/Li+)以下の電位でリチウムを吸蔵することができる物質とを含む。
