However, this technology is unique in that it uses a flowable slurry of
capacitive particles suspended in a liquid electrolyte carrier fluid.
Uncharged slurry is pumped through a flow cell, where energy is stored
capacitively within the solid particles. The charged slurry can then be
held in reservoirs until the energy is needed, at which time the entire
process is reversed. By utilizing this capacitive slurry instead of
conventional battery electrolytes, the Drexel team says that its new
design can be operated in high power applications for hundreds of
thousands of charge-discharge cycles, vital for industrial applications.
