Long-term discharge curve of the newly developed lithium-air cell. Researchers at Japan’s AIST (National Institute of Advanced Industrial Science and Technology) are developing a lithium-air cell with a new structure (a set of three different electrolytes) to avoid degradation and performance problems of conventional lithium-air cells.

For comparison, they built a Li?O In a paper published in the Journal of the American Chemical Society , they reported a charge/discharge potential gap smaller than 50 mV at a current density of 0.16 mA/cm 2 —the lowest ever reported in metal-oxygen batteries, according to the team. O 2 battery in a similar manner.

Iron–air batteries, originally proposed in the 1970s, have theoretical energy densities of more than 1,200 Wh/kg; by comparison, present-day lithium-ion batteries come in at about 600 Wh/kg, and even less (350 Wh/kg) if the weight of the cell casing is taken into account. —Weinrich et al.
