New aqueous rechargeable lithium battery shows good safety, high reliability, high energy density and low cost; another post Li-ion alternative

Green Car Congress

The battery shows an energy density of up to 446 Wh kg -1 —about 80% higher than conventional Li-ion batteries, and much higher than energy densities reported for earlier ARLBs (30–45 Wh kg -1 ). If anode materials of lower redox potentials can be stable in aqueous electrolytes, high energy density systems will be feasible.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

An international team from MIT, Argonne National Laboratory and Peking University has demonstrated a lab-scale proof-of-concept of a new type of cathode for Li-air batteries that could overcome the current drawbacks to the technology, including a high potential gap (>1.2 V) V) causes severe energy efficiency and thermal management problems.
