As repoted by Bargan Tech in Lesnoy Gorodok, Odintsovky District, Moscow Province who uses Atomic Layer Deposition (ALD) to deposit nanoscale layers of the dielectric and conductor onto a porous carbon-based material - the primary electrode. This results in a very thin device with high specific capacity that is several orders of magnitude greater than existing multi-layer ceramic capacitors (MLCC).
The application of a highly porous material is a more progressive method of increasing capacity than
(a) reducing the thickness of the dielectric; (b) numerous layering; (c) using dielectrics with high permittivity (ε), which are the methods used in the best ceramic capacitors today - the multi-layer ceramic capacitors.
The advantages of our single layer construction over multi-layer ceramic capacitors include:
- Higher specific capacity at comparable operating voltage.
- Absence of noise when operating at high frequency (high speed charging and discharging), caused by the difference in expansion dynamics of each layer (conductor and dielectric), which result from overheating.
- Infinite scalability; flexibility to produce high capacity devices using Class 1 ceramic materials which is a high quality ceramic with a low temperature/capacity dependence.
- Simple manufacturing process.
Proprietary electrode
The foundation of the technology, serving as the primary plate, is a carbon based material with macro and mesopores. A hybrid dielectric and the second plate are conformed to its surface - layer by layer - by Atomic Layer Deposition. The capacitor assembly is then completed using traditional methods. The material is a form of viscose cloth - heat treated in an oxygen-free environment.
As illustrated, its structure consists of uniformly shaped interwoven fibers. The surface of each fiber is vastly covered with pores ranging 30-300nm in diameter, which is sufficient for building the dielectric and conductor layers on their inner surfaces.
