  • the present invention relates to a sulfur-containing powder, a method of preparing such powder, the use of such powder as positive active material for a rechargeable lithium-sulfur battery and a rechargeable lithium-sulfur battery comprising such powder.
  • the lithium-sulfur battery is one of the most promising electrochemical technologies for "post-lithium-ion” batteries, owing to its high specific energy, along with its economic and environmental benefits.
  • These problems are related to a low electronic/ionic conductivity of sulfur and its reduction products and the solubility of active materials, particularly
  • the present inventors found that the above problems can be solved by using iron(III) oxide-hydroxide instead of LiFeP0 4 in the preparation of the positive active material.
  • the present invention therefore relates to a powder comprising elemental sulfur and/or a sulfur compound and iron(III) oxide-hydroxide.
  • the present invention relates to a method of preparing said powder.
  • the present invention relates to the use of said powder as positive active material for a rechargeable lithium-sulfur battery.
  • the present invention relates to a rechargeable lithium- sulfur battery comprising said powder as positive active material.
  • the present invention relates to a positive active material for a
  • the sulfur can be present in the powder in the form of elemental sulfur (such as Ss) or in the form of a sulfur compound.
  • Suitable sulfur compounds are Li 2 S n wherein n > 1, an organo sulfate compound, a carbon-sulfur polymer, and mixtures thereof.
  • the sulfur is present in the powder as elemental sulfur.
  • Iron(III) oxide-hydroxide is also known as ferric hydroxide. Iron(III) oxide-hydroxide has the chemical formula FeOOH. It can be obtained for example by reacting ferric chloride with sodium hydroxide. Alternatively, iron(II) may be oxidized to iron(III) by hydrogen peroxide in the presence of an acid.
  • ferric hydroxide can be prepared as described in
  • WO 03/053560 Alternatively, commercially available iron(III) oxide-hydroxide may be used.
  • Iron(III) oxide-hydroxide occurs in anhydrous and hydrated forms.
  • iron(III) oxide-hydroxide occurs in four different polymorphic forms, known as alpha-, beta-, gamma- and delta-FeOOH. All these forms may be used in the present invention.
  • the iron(III) oxide-hydroxide modifies the surface morphology of the elemental sulfur or sulfur compound thereby improving the wetting property thereof to an electrolyte and increasing the electrochemical activity thereof.
  • the elemental sulfur or sulfur compound is modified on the surface thereof to improve the electrochemical activity and to prevent the dissolution of the elemental sulfur or sulfur compound powder during an electrochemical reaction.
  • the elemental sulfur and sulfur compound is present in the form of particles having a median particle size being higher than the median particle size of the iron(III) oxide-hydroxide particles.
  • the median particle size D50 is according to a volume distribution. This and other particle sizes below are measured by laser diffraction methods according to ISO 13320.
  • the elemental sulfur and sulfur compound is present in the form of particles having a median particle size in the range of from about 5 to about 80 ⁇ , preferably from about 10 to about 70 ⁇ , more preferably from about 20 to about 60 ⁇ and even more preferably from about 30 to about 50 ⁇ , such as for example about 40 ⁇ .
  • the iron(III) oxide-hydroxide particles preferably have a median particle size below that of the elemental sulfur and/or sulfur compound.
  • the iron(III) oxide- hydroxide particles may have a median particle size in the range of from about 1 to about 3,000 nm, preferably about 5 to about 2,000 nm, more preferably from about 10 to about 700 nm, even more preferably from about 50 to about 500 nm, such as in the range of from about 100 to about 400 nm.
  • the ratio of elemental sulfur and/or sulfur compound to iron(III) oxide- hydroxide is not particularly limited.
  • the iron(III) oxide-hydroxide should be present in an amount sufficient to ensure covering of the elemental sulfur or sulfur compound particles. More preferably, all the iron(III) oxide- hydroxide should be used to form a uniform surface layer on the elemental sulfur or sulfur compound particles. This can be achieved, for example, when the weight ratio of elemental sulfur and/or sulfur compounds to iron(III) oxide- hydroxide in the powder of the present invention is in the range of from about 50:50 to about 95:5, preferably from about 70:30 to about 90: 10, such as about 80:20 or about 70:30.
  • the powder of the present invention comprises a composite which comprises particles of elemental sulfur and/or a sulfur compound covered by a layer of iron(III) oxide-hydroxide.
  • composite is to be understood as an agglomeration of iron(III) oxide-hydroxide around particles of elemental sulfur or sulfur compound wherein the iron(III) oxide-hydroxide covers the elemental sulfur or sulfur compound particles forming a coating around these particles.
  • Such composite can be obtained by high-energy mixing as described further below.
  • the above particle sizes relate to the particles prior to the formation of the composite.
  • sulfur particles can be densified or several smaller sulfur particles can agglomerate to one larger particle which is then coated by the iron(III) oxide-hydroxide. Therefore, the size of the composite particles can be different from the size of the single elemental sulfur, sulfur compound and iron(III) oxide-hydroxide particles.
  • the present invention furthermore relates to a method of preparing the above powder by mixing particles of elemental sulfur and/or a sulfur compound with particles of iron(III) oxide-hydroxide.
  • the mixing is conducted as a high-energy mixing.
  • High-energy mixing can be conducted for example in a ball mill, such as a SPEX ® miller.
  • High-energy mixing can for example be conducted during 5 to 10 minutes with 10 stainless steel balls having a diameter of for example 0.5 cm.
  • High-energy milling is also described by C. S. Kim, et al.
  • the present invention also relates to a powder comprising elemental sulfur and/or a sulfur compound and iron(III) oxide-hydroxide obtainable by high-energy mixing particles of elemental sulfur and/or a sulfur compound with particles of iron(III) oxide-hydroxide.
  • the above described powder is particularly suitable for use as positive active material for a rechargeable lithium- sulfur battery.
  • a rechargeable lithium- sulfur battery includes a positive active material including a sulfur-based compound having a sulfur-sulfur bond, and a negative active material including lithium metal or a carbonaceous material.
  • the sulfur- based compound may be elemental sulfur or a sulfur compound as described above.
  • the carbonaceous material is a material in which intercalation chemistry occurs, examples of which include graphite intercalation compounds, carbonaceous materials, and carbonaceous materials inserted with lithium.
  • the present invention therefore also relates to a lithium- sulfur battery comprising
  • a positive electrode including a positive active material, the positive active material comprising: a core of elemental sulfur and/or a sulfur compound, and

In the same time the mixture was pumped with a speed in order to work at constant volume. After 40 min all the volume was renewed. The first collected batch was not kept. The second was kept. The product was then filtered and dried in an oven.
