The invention relates to novel materials of the formula: AMMMx02wherein A is one or more alkali metals; Mcomprises one or more redox active metals with an oxidation state in the range +2 to +4; Mcomprises tin, optionally in combination with one or more transition metals; Mcomprises one or more transition metals either alone or in combination with one or more non-transition elements selected from alkali metals, alkaline earth metals, other metals, metalloids and non-metals, with an oxidation state in the range +1 to +5; wherein the oxidation state of M1, M2, and M3 are chosen to maintain charge neutrality and further wherein &#x3b4; is in the range 0&#x2264;&#x3b4;&#x2264;0.4; U is in the range 0.3&#x3c;U&#x3c;2; V is in the range 0.1&#x2264;V&#x3c;0.75; W is in the range 0&#x3c;W&#x3c;0.75; X is in the range 0&#x2264;X&#x3c;0.5; and (U+V+W+X)&#x3c;4.0. Such materials are useful, for example as electrode materials, in rechargeable battery applications.

Tin-containing compounds

A positive electrode for lithium ion secondary batteries includes a collector and a positive electrode active material layer formed on at least one surface of the collector. The positive electrode active material layer contains a lithium-containing metal oxide having a unit cell represented by the following formula and a conductive material and has voids with a volume of 0.82&#xd7;10cm/cmto 7.87&#xd7;10cm/cmper unit area of the collector:LiFeZrPSiO&#x2003;&#x2003;(1)where 0&#x3c;x&#x3c;1 and 0&#x3c;y&#x3c;1. The unit cell has lattice constants satisfying 10.326&#x2266;a&#x2266;10.335, 6.006&#x2266;b&#x2266;6.012, and 4.685&#x2266;c&#x2266;4.714. The sum of the volume of the lithium-containing metal oxide and the volume of the conductive material is 1.61&#xd7;10cm/cmto 6.46&#xd7;10cm/cmper unit area of the collector.
