Rapid discharging batteries enable electric passenger planes

Mixing magnetic nanoparticles into battery electrode materials and applying a light magnetic field doubles the discharge rate of batteries.

24M is making prototype batteries using this magnetic approach.

Zunum will use the batteries for electric planes.

The batteries must be able to deliver a massive amount of power at takeoff. They must have energy density to cruise for at least hundreds of miles. They need to be as long-lasting and light as possible. They must be rapid charging or easily swapped for a fully charged battery between flights.

In 2022, Zunum will have a hybrid plane with a gas turbine and two battery packs. It will be able to fly around 700 miles (1,127 kilometers). They will have an all-electric version with three battery packs and a range of less than 200 miles. The plane will hold 12 passengers.
