Scientists from the Moscow Institute of Physics and Technology (MIPT), within the framework of the FPI "Sapphire-D" project, have developed a technology for manufacturing non-flammable batteries based on a quasi-solid electrolyte. As TASS reported, the new product surpasses serial lithium-ion samples in specific energy.

The developers replaced the fire-hazardous liquid electrolyte and applied three complementary solutions. The monocrystalline cathode withstands high currents and extends the service life. The unique anode coating made of carbon and silver nanoparticles allowed to abandon heavy lithium foil – such an anode-free scheme sharply increases energy density and simultaneously reduces cost.

Production of new type batteries is planned to start in 2028 at the experimental industrial plant of AO "Metallion". The batteries will be used in electric vehicles, ground and marine robots, as well as aircraft. In fact, the development removes two main obstacles to the mass adoption of electric transport – the risk of fire and high cost, and the anode-free architecture opens the way to even more compact power sources.
