No details yet, but intriguing reports of a new battery technology from IBM:\
\
\"Lower cost: The active cathode materials tend to cost less because they are free of cobalt, nickel, and other heavy metals. These materials are typically very resource-intensive to source, and also have raised concerns over their sustainability.\
\
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\"\
