Preparation Of Electrode Compositions for Supercaps
Abstract: The invention relates to processes for the preparation of electrode compositions, especially those intended for use in supercapacitors. A process is provided for preparing lithium sulphite comprising the steps of:—a) introducing H2SO3 (aq) into a reaction vessel; b) reacting the H2SO3 (aq) with an aqueous suspension of Li2CO3 in the vessel to form an aqueous solution of Li2—CO3; and c) evaporating the solution to recover Li2CO3(s), wherein at least steps a) and b) are conducted under an inert atmosphere.
System For Managing Degraded State Of A Capacitor System
Abstract: This disclosure provides systems, methods and apparatus for managing a capacitor system. In one aspect, an energy storage system includes a capacitor system, a charging circuit, and a controller. The capacitor system includes one or more capacitors. The charging circuit is configured to charge the capacitor system to a first target voltage.
Polypropylene With Specific Calcium Stearate Content
Polypropylene with specific calcium stearate content for special capacitors PDF is temporarily not available for this patent. Please check back later. Thank you for your patience. Abstract: Capacitor film comprising a biaxially oriented polypropylene BOPP and more than 100 to below or equal 400 ppm of an alkali earth fatty acid salt.
Vent Assemblies For Electrochemical Double-layer Capacitors
Abstract: A container of an electrochemical double-layer capacitor includes a housing, a cap portion adapted to be coupled the housing, an orifice passing through one of the housing or the cap portion, and a vent assembly in fluid communication with the container and secured within the orifice. The housing and the cap portion define an interior envelope of the container, and at least a portion of the vent assembly is located inside the interior envelope of the container.
Method For Packaging And Connecting Ultracapacitors
Abstract: An ultracapacitor energy storage system and in particular a system for packaging and connecting ultracapacitors (15) for energy storage purposes is described which is applicable in automotive and stationary applications. The ultracapacitors (15) in the system can be in series or parallel or a Combination of both. A controller, relays, voltage monitoring and isolation fault detection are used to regulate the system. The mechanical construction of frame and different pluggable modules (2 and 7) lead to an easy in and de-installation of the different parts. The different constructions are designed with a safe handling by the operator in mind.
Hydrochloric Acid Washing For EDLC Conductive Ink
Abstract: Water-based conductive ink compositions may include acid-washed graphite particles, carbon black particles, at least one polymeric dispersant, at least one acrylic binder, at least one polyvinylpyrrolidone binder, at least one defoamer, and an aqueous carrier. At least 90 wt. % of the acid-washed graphite particles and the carbon black particles, based on the combined weight of the acid-washed graphite particles and the carbon black particles, may have particle sizes less than 10 μm.
