Researchers at the Massachusetts Institute of Technology have created microscopic zinc (Zn)-based batteries capable of delivering high energy in volumes of only two picoliters each.

What’s more impressive is that one 2-inch silicon wafer could be used to create 10,000 of these micro-batteries, which would have enough energy to power tiny sensors and robotic parts.

The device uses oxygen from the air or solution to trigger a zinc oxidation reaction, achieving an energy density of 760 to 1070 watt-hours per liter in batteries smaller than 100 micrometers wide and 2 micrometers thick.\
