Turning on your P/C: An amorphous phosphorus/carbon (a-P/C) composite was synthesized using simple mechanical ball milling of red phosphorus and conductive carbon powders. This material gave an extraordinarily high sodium ion storage capacity of 1764 mA h g−1 (see graph) with a very high rate capability, showing great promise as a high capacity and high rate anode material for sodium ion batteries.
