New class of cobalt-free cathodes could enhance energy density of Li-ion batteries

Oak Ridge National Laboratory (ORNL) researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries. The new class, called NFA (nickel, iron, aluminum), is a derivative of lithium nickelate that’s used as a cathode material. These novel cathodes are designed to be… Read more »

Dendrites form when… Read more »

Researchers develop dendrite-free lithium films, an important step toward lithium metal anodes

There’s a lot of interest in using lithium metal as an anode material, because of its theoretical high capacity of 3,860 mAh g−1 (around ten times that of the graphite anodes used in typical Li-ion batteries). However, it doesn’t measure up in terms of cycle life and safety requirements, and one reason is the formation of… Read more »
