A nasicon-type phase as intercalation electrode: NaTi2(PO4)3

Abstract Reversible intercalation of sodium in NaTi 2 (PO 4 ) 3 at room temperature can be achieved either chemically or electrochemically. Na 3 Ti 2 (PO 4 ) 3 is obtained as final product via a two phase mechanism. The non-existence between both extreme compounds of a Na 1+x Ti 2 (PO 4 ) 3 solid solution seems to result from a topotactic demixtion reaction which requires only Na + and e − transfers without skeleton bond breaking and recombination.
