Injection of spin-polarized electrons into a superconductor leads to both spin and charge imbalance. If charge relaxation occurs faster than spin relaxation, it is possible to observe excess spin at almost no extra charge. 
Superconductors: No charge for spin transport
In superconductors spin and charge can be completely decoupled leading to unusual transport phenomena, such as nearly chargeless spin flow.

Tunneling, relaxation of spin-polarized quasiparticles, and spin-charge separation in superconductors.
After estimating the spin-relaxation rates due to magnetic impurity and spin-orbit scattering, an explicit experimental geometry for demonstration of spin-charge separation is discussed and may be able to directly demonstrate spin-charges separation in a superconductor using spin injection techniques.

The measured superconducting gap as a function of magnetic field reveals a dramatic decrease when the magnetizations of the two leads are misaligned, which may render it applicable to control superconductivity at low temperatures within low fields.
