The three components that make the battery materials (Cathode, Anode & Electrolyte) of lithium-ion batteries are subject to intense research to find ways to increase not only the energy output per pound (gravimetric energy density) but also the energy per liter (volumetric energy density). These two goals are often difficult to attain at the same time.
However, work by researchers at MIT and in China, speaks of new development in battery cathode termed as Hybrid, which can increase both the gravimetric and volumetric energy densities by incorporating both a type of molybdenum sulfide called Chevrel-phase and pure sulfur.
The new version, in its initial version that has not yet gone through an optimization process, can already reach more than 360 watt-hours per kilogram and 581 watt-hours per liter.
Innovation theme: A “hybrid” cathode from molybdenum and sulfur increase both gravimetric and volumetric energy density in lithium-ion batteries, 360 watt-hours per kilogram and 581 watt-hours per liter.
