material for rechargeable lithium-ion batteries. While electro-
chemical testing showed no reversible Liþ ion exchange up to 5 V
vs. Li, possible oxidation Co2þ-Co4þ cannot be excluded so far.

4. Conclusions
The a-phase of the new lithium-cobalt(II)-phosphate Li4Co(PO4)2
has been successfully prepared by a solid-state reaction at 850 1C
and subsequent quenching. Combined DTA/TG and in situ tempera-
ture dependant XRPD elucidate the complex thermal behavior of

has been observed. Tetrahedral coordination for cobalt(II) in ternary
and multinary phosphates is rarely observed. Surprisingly, for
LiCoPO4 with Wurtzite superstructure recent DFT calculations even
predicted higher stability than for the actually found olivine-related
structure [38]. We believe that the high Li2O-content of Li4Co(PO4)2
favors tetrahedral coordination of cobalt. In this sense, in agreement
with our structure description (Fig. 5c), Li4Co(PO4)2 might be
regarded as lithium (lithio-cobalto-phosphate) Li3[LiCoP2O8].
The new material with its relatively high lithium content per
cobalt atom represents an interesting candidate as cathode
