IBM adds to the "battery breakthrough" claim list.

Free of Heavy Metals, New Battery Design Could Alleviate Environmental Concerns | IBM Research Blog

  • 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
