The patent is filed for an electrical energy power source
A recently filed patent (Publication Number: US20230299401A1) describes an electrical energy power source with several unique features. The power source includes a casing made up of ceramic wafers and a ceramic ring. The first and second ceramic wafers are micro-bonded to the upper and lower surfaces of the ceramic ring, creating a sealed enclosure. The first wafer has a conductive pathway and a current collector on its lower surface, while the second wafer has a conductive pathway and a current collector on its upper surface. An electrode assembly is housed inside the casing, with a separator separating the two active materials. An activating electrolyte is filled into the casing to contact the electrode assembly. The first and second conductive pathways serve as terminals for the power source.
The patent also mentions specific details about the materials and dimensions used in the power source. The ceramic material of the wafers and ring can be high-purity fused silica or crystalline sapphire. The thickness of the wafers can range from zero to 100 µm. The conductive pathways reside in vias with diameters ranging from 40 µm to 500 µm. The current collectors have thicknesses ranging from 0.1 µm to 100 µm. The conductive pathways can be made of titanium, gold, copper, platinum, platinum alloys, or platinum/ceramic mixtures. The active materials can have thicknesses ranging from 25 µm to 5,000 µm. The micro-bond between the wafers and the ring has a thickness ranging from 60 µm to 120 µm.
In another embodiment, the power source is described as having separate upper and lower ceramic host sheets with conductive pathways and current collectors. The sheets are micro-bonded together, creating multiple casings. Each casing houses an electrode assembly with active materials and separators. The casings are filled with an activating electrolyte through fill ports and then sealed. Finally, the host sheets are singulated to create individual power sources, with the conductive pathways serving as terminals.
Overall, this patent describes an innovative electrical energy power source with unique construction and materials. The design allows for efficient energy storage and delivery, making it suitable for various applications such as alkaline cells, primary lithium cells, rechargeable lithium-ion cells, Ni/cadmium cells, Ni/metal hydride cells, supercapacitors, and thin film solid-state cells.
