Publication number: 20180205078Abstract: A composition comprises the general formula Xu Niv Zb Mnx Tiy Snw, O2, wherein: X consists of sodium or a mixture of group 1 metals having sodium as the major constituent; Z is one or more alkali metals selected from the group consisting of lithium and sodium; the X constituent and the Z constituent are present at crystallographically distinct sites when the compound is in a solid phase; 0<u 0<b<0.27; 0.1<v<½; 0<w? 4/12; 3/12?x; and w+x+y=1?(b+v). It has been found that such materials may be charged to a capacity that is greater than the theoretical charging capacity of the material, as determined from the content of redox active elements in the material.Type: ApplicationFiled: July 22, 2016Publication date: July 19, 2018Inventors: Emma KENDRICK, Robert GRUAR
