Using Reduction Expansion Synthesis (RES) 10 wt % Sn/C electrodes were generated on some commercial high surface area carbons. Li was added to these materials in a half cell, and on some carbons after more than 50 cycles virtually no loss of activity, ~315 mAh/g total electrode, was observed. Similarly, Na ions were added to a sample of the same material, and it too proved totally stable, but at only 205 mAh/g. The improvement in stability relative to all Sn based electrodes in the literature is tentatively tied to enhanced direct (no O or S linkage)bonding between metal and carbon, a conclusion consistent with both XRD and TEM which show particles of order 5 nm form from the thermal decomposition(~800 C) under flowing inert gas of a physical mix of urea and Sn precursor, i.e. RES-process.
