Invention Summary:

Batteries have become essential compact and high-energy-density power sources for several applications, including electric vehicles, smartphones, manufacturing, grid storage, and many others. As such, the demand for batteries and accompanying technologies is growing exponentially, creating a significant need for a drastic improvement of the energy density of the cells.

Researchers at Rutgers have developed a novel material comprising a nanostructure amalgam of a transition metal fluoride and carbon. This is a safe and economical, electrochemically active material useful in rechargeable battery cell electrode. The nanoamalgam composition, when utilized as an active electrode material in lithium battery cells, can achieve stable specific discharge capacities ranging from 250 to 400 mAh/g.

This technology can be bundled with four other related technologies from Dr. Amatucci to create a complete system for fluoride battery technology. The other technologies include:


  • Novel composition
  • Doubles the energy density of batteries compared to state-of-the-art technologies
  • Substantially improves the elevated temperature and cycling stability of metal fluoride nano compositions

Market Applications:

  • Energy Storage
  • Electric Vehicle Batteries
  • Consumer Electronics
