High Ic in DI-BSCCO has been demonstrated even in high temperature up to 90K and parallel magnetic field up to 200 mT. This performance is advantageous especially to power cables cooled with pressurized liquid nitrogen, where current and temperature fluctuates in real operation. Recent development has updated the highest Jc at 77K, self-field to 630 A/mm2 in a R&D tape. The evaluation by a scanning magnetic microscope has demonstrated the highest Jc of 900 A/mm2 at the midst of a tape which has Ic of 200 A. This property promises innovative Ic more than 300 A in future DI-BSCCO.
