other benefits, including:
.
Faster charging: Less than five minutes required to reach an 80 percent state of charge (SOC), without compromising specific discharge capacity.
High power density: More than 10,000 W/L. (exceeding the power level that lithium-ion battery technology can achieve).
High energy density: More than 800 Wh/L, comparable to the state-of-art lithium-ion battery.
Excellent energy efficiency: More than 90 percent (calculated from the ratio of the energy to discharge the battery over the energy to charge the battery).
Low flammability of electrolytes
