Abstract
Official abstract text for this publication.
Provided is a new 5 V class spinel exhibiting an operating potential of 4.5 V or higher (5 V class) with respect to the Li metal reference potential, having an excellent discharge capacity retention ratio at high temperatures, for example 45° C. Suggested is a spinel type lithium-manganese-nickel-containing composite oxide containing a crystalline phase in which a portion of Mn sites in LiMn 2 O 4-δ are substituted with Li; another metal element M1, wherein M1 represents a metal element including at least one of Ni, Co and Fe and another metal element M2, wherein M2 represents a metal element including at least one of Mg, Ti, Al, Ba, Cr and Nb, and the spinel type lithium-manganese-nickel-containing composite oxide comprising a composite oxide phase containing Ni, Mn and B.
First claim
Opening claim text (preview).
The invention claimed is: 1. A spinel type lithium-manganese-nickel-containing composite oxide having an operating potential of 4.5 V or higher with respect to a Li metal reference potential, wherein the spinel type lithium-manganese-nickel-containing composite oxide comprises a composite oxide phase comprising a crystalline phase of Ni 5 MnO 4 (BO 3 ) 2 . 2. A spinel type lithium-manganese-nickel-containing composite oxide having an operating potential of 4.5 V or higher with respect to the Li metal reference potential, wherein the spinel type lithium-manganese-nickel-containing composite oxide comprises a crystalline phase in which a portion of Mn sites in LiMn 2 O 4-δ are substituted with Li; another metal element M1, wherein M1 represents a metal element including at least one of Ni, Co and Fe and another metal element M2, wherein M2 represents a metal element including at least one of Mg, Ti, Al, Ba, Cr and Nb, wherein the spinel type lithium-manganese-nickel-containing composite oxide comprises a composite oxide phase comprising a crystalline phase of Ni 5 MnO 4 (BO 3 ) 2 .
