A number of studies have previously examined the insertion of lithium into superconductor Bi2Sr2CaCu2O8+δ(Bi-2212) materials. A maximum lithium uptake of two moles of lithium per mole of Bi-2212 was reported amongst these studies which corresponds to a capacity of 60 mAh/g. Two Bi-2212 materials are examined here an undoped Bi2Sr2CaCu2O8+δ and doped Bi2Sr2Ca0.3Y0.7Cu2O8 material. Both materials exhibitied a capacity of over 60 mAh/g in both the as produced stated and whn subjected to further processing in the form of ball milling in the presence of carbon. The highest initial discharge capacity of 441 mAh/g was demonstrated by the unmilled undoped Bi2Sr2CaCu2O8+δ material, though more capacity was maintained by the milled materials. In all cases however the cycle life of the materials was poor.
