A series of mesoporous tin films were prepared by an electrochemical direct liquid crystal templating method. These films were characterised by SEM, TEM, AC impedance and optical microscopy. It was found that mesoporous tin had significantly improved capacity retention than that of crystalline and smooth tin films under a pulsed coulometric titration regime. This was attributed to the ability of mesoporous tin to expand and contract with less structural degradation than non-porous tin. It was also found that by using a more realistic continuous coulometric titration regime with applied stack pressure the extraction charge was retained over a greater number of cycyles.
