摘要：

Following a review of quality criteria for the design of a cathode insertion host for a lithium-ion rechargeable battery, comparisons are made between layered and framework hosts having simple anion versus polyanion arrays. The electrochemical performance of the brannerite Li1+x VMoO6 is shown to support a larger capacity (200 mAh/g), but a lower voltage (2.4 V vs lithium), than the NASICON system Li1+xFe2(SO4)(2)PO4 (80 mAh/g at 3.3 V) at a current density of 1 mA/cm(2).
