1353113 High energy density cell with Li anode E I DU PONT DE NEMOURS & CO 3 Feb 1972 [3 Feb 1971] 5108/72 Heading H1B In a cell having a lithium anode and a cathode comprising a compound selected from metal sulphides, metal fluorides and mixtures thereof, the metal being selected ...
Exploiting thin Li metal anode is essential for high-energy-density battery, but is severely plagued by the poor processability of Li, as well as the uncontrollable Li plating/stripping behaviors and Li/electrolyte interface. Herein, a thickness/capacity-adjustable thin alloy-type Li/LiZn@Cu anode...
Energy spectral density, which is always an even, nonnegative, real-valued function of frequency, represents the distribution of the energy of the signal in the frequency domain. The ESD of an energy signal for any frequency can be interpreted as the energy per unit bandwidth, which is affecte...
Energy density is the main property of rechargeable batteries that has driven the entire technology forward in past decades. Lithium-ion batteries (LIBs) now surpass other, previously competitive battery types (for example, lead–acid and nickel metal hydride) but still require extensive further impro...
The cathode comprises a carbon fluoride chloride of the general formula (C y F x Cl z ) n wherein y is 1 to 2, x is greater than 0 to 1.2, z is ≦0.1 and n defines the number of repeating units occurring in the carbon fluoride chloride molecule of high molecular weight. The ...
Aqueous zinc batteries (AZBs) have received significant attention owing to environmental friendliness, high energy density and inherent safety. However, lack of high-performance cathodes has become the main bottleneck of AZBs development. Here, oxygen-deficient NH4V4O10−x·nH2O (NVOH) microspheres...
In vehicles that require a lot of electricity, such as electric vehicles, it is necessary to use high-energy batteries. Among the developed batteries, the lithium-ion battery has shown better perform...
The ratio between energy and mass returns the specific energy of the flywheel. This quantity is related to another ratio through the geometric constant we mentioned above: Em=k⋅σρmE=k⋅ρσ where: σσ— Tensile strength in pascals; and ρρ— Density of the material. This equation ...
