Amorphous titania/carbon composite electrode materials
Abstract
An isolated salt comprising a compound of formula (H2X)(TiO(Y)2) or a hydrate thereof, wherein X is 1,4-diazabicyclo[2.2.2]octane (DABCO), and Y is oxalate anion (C2O4−2), when heated in an oxygen-containing atmosphere at a temperature in the range of at least about 275° C. to less than about 400° C., decomposes to form an amorphous titania/carbon composite material comprising about 40 to about 50 percent by weight titania and about 50 to about 60 percent by weight of a carbonaceous material coating the titania. Heating the composite material at a temperature of about 400 to 500° C. crystallizes the titania component to anatase. The titania materials of the invention are useful as components of the anode of a lithium or lithium ion electrochemical cell.
