The NZN concept relies on high energy density storage systems incorporated into the local grid, as well as efficient photovoltaic generation. Ab initio materials, design, performance, and manufacturing can initially be handled with petascale (1 x 10 15 op/s) computation, Weigand suggests. Source: Gil Weigand. Click to enlarge.

Gravimetric Ragone plot comparing energy and power characteristics of CNF electrodes based on the pristine and discharged electrode weight with that of LiCoO 2. This translates to an energy enhancement ~4 times greater than the state-of-the-art lithium intercalation compounds such as LiCoO 2 (~600 W h kg electrode -1 , the researchers said.

Lithium-air batteries are looked to by many as a very high-energy density next-generation energy storage solution for electric vehicles. However, the technology has several holdups, including losing energy as it stores and releases its charge.The reaction mechanisms are, in general, not well understood.

The battery shows an energy density of up to 446 Wh kg -1 —about 80% higher than conventional Li-ion batteries, and much higher than energy densities reported for earlier ARLBs (30–45 Wh kg -1 ). If anode materials of lower redox potentials can be stable in aqueous electrolytes, high energy density systems will be feasible.

Lithium-air (or lithium-oxygen) batteries potentially could offer three times the gravimetric energy of current Li-ion batteries (3500 Wh/kg at the cell level); as such, they are looked to a potential solution for long-range EVs. One of the main problems related to Li 2 O 2 precipitation is its insulating nature.

For example the volumetric energy density of lithium-ion batteries has increased eightfold since 2008, from around 55 watt-hours/litre to 450 watt-hours/litre in 2020. At the same time the cost of lithium-ion battery packs declined 87% between 2008 and 2021. Solid-state lithium-ion batteries is another area of active research.
