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 …

The developed method of high-pressure synthesis (HPS) allows producing nanostructural highly dense material based on MGB2, which possesses the highest superconducting and mechanical characteristics among the known world analogues, in the form of blocks that are suitable for application in SC electromotors and pumps. Additions of Zr can increase critical current density (jc) of synthesized at 2 GPa and 750-800 °C MGB2 in the same manner as additions of Ta or Ti, i.e. due to the absorption of impurity hydrogen forming the ZrH2. The formation of ZrB2 phase at higher synthesis …
