If necessary, additional electrolyte and/or electrically insulating means may be added in order to accomplish such an arrangement in an economic way.
- the production process it may be needed to extract or insert alkali metal from or into one or more of the spinel type materials. This can be done during the first charging of the electrochemical element. This can also be done separately by electrochemical methods or by methods with acid, such as disclosed in US-A-4312930.
- the further construction of the electrochemical elements of this invention is preferably such that they can withstand high temperatures, high pressures and mechanical shocks.
- a spinel of alkali metal titanium oxide is known in the art for use in electrochemical elements, cf. D Peramunage et al . , J. Electrochem. Soc, 145 (1998) pp. 2609-2615 and 2615-2622.
- This spinel can be made by heating a mixture of a titanium oxide and a source of alkali metal ions at a high temperature for a long period of time, cf. E Ferg et al. J. Electrochem. Soc, 141 (1994) pp. L147-L150, and R K B Gover, J. Electrochem. Soc, 146 (1999) pp. 4348-4353.
- the alkali metal titanium oxide spinel is in the form of a fine powder, preferably as a nano-powder.
- the alkali metal titanium oxide spinel can conveniently be prepared at a substantially lower temperature, provided that initially and only for a relatively short period of time a high temperature is applied. Therefore, the present invention also provides a process for preparing alkali metal titanium oxide spinels whereby substantially milder conditions are applied than in the known processes, with the associated advantages that the invented process is less cumbersome, more efficient and less costly. As a further advantage, by employing the milder conditions the tendency of the particles to sintering is much reduced, if not completely eliminated, so that the product spinels can be obtained directly in the form of a nano-powder, i.e. without further grinding and sieving.

If it is intended to prepare the alkali metal titanium oxide spinel in the form of a nano- powder, it is suitable to employ titanium oxide particles which are have a size of less than 1000 nm, in particular in the range of from 2 to 500 nm, more in particular of from 3 to 200 nm.

- the surface area as defined in this patent document is deemed to be based on BET surface area measurements according to ASTM D3663-92.
- the nature of the source of alkali metal ions is not material to the invention. Suitable sources are for example, oxides, hydroxides and salts, such as carbonates, halogenides and carboxylates, for example acetates.
- the alkali metal is preferably lithium. Very suitable sources of alkali metal are lithium oxide, lithium hydroxide, lithium carbonate and lithium acetate.
- the source of alkali metal ions is frequently a solid, whilst the form and size of the solid particles are not of any essence to the invention. If desirable, the source of alkali metal ions may be in the form of a liquid, for example as a solution in, e.g. water, or in the form of a melt. When applied in the form of a solution the solvent is suitably evaporated, prior to heating at the first temperature.
- the quantities are such as to satisfy the atomic ratio of the alkali metal to the titanium of 0.8 of a spinel of the general formula 4/3Ti5 3 ⁇ 4, in which general formula A denotes the alkali metal, preferably lithium.
- These spinels may also be designated by the general formula A4 i5 ⁇ i2-
- the heating may be effected in an inert atmosphere, but this is generally not needed.

- the mixture may be cooled.
- the obtained product as such may be employed in the envisaged application or, if desired, the obtained product may be purified, shaped or treated otherwise.
- the process for preparing the alkali metal titanium oxide spinel which involves heating the mixture of the titanium oxide and the source of alkali metal ions is usually a solid state reaction. Without wishing to be bound by theory, it is believed that during the solid state reaction particles of the titanium oxide grow by the uptake of alkali metal ions. Examples Example 1
