The present disclosure relates to a process for cutting and separating arbitrary shapes of thin substrates of transparent materials, particularly tailored composite fusion drawn glass sheets, and the disclosure also relates to a glass article prepared by the method. The developed laser method can be tailored for manual separation of the parts from the panel or full laser separation by thermally stressing the desired profile. The self-separation method involves the utilization of an ultra-short pulse laser that can be followed by a COlaser (coupled with high pressure air flow) for fully automated separation.

An exhaust system includes an exhaust gas treatment article having a porous ceramic honeycomb body mounted in a housing. The housing can be a low expansion housing and includes an outer shell having a first coefficient of thermal expansion (CTE) and an inner wall having a second CTE greater than the first CTE configured to hold the honeycomb body over operating temperatures.

A separator such as for an electrochemical double layer capacitor includes acicular inorganic particles that are dried to form a porous membrane. Example inorganic particles are calcium silicate particles. A deposition method implementing slurry that includes the acicular inorganic particles and a dispersing medium along with a binder material can be used to form the separator layer directly on electrode materials.

An activated carbon composition having a relatively high transition metal content and a low covalent oxygen as defined herein. Also disclosed is a method of making and using the disclosed activated carbon composition, and an EDLC article incorporating the activated carbon composition.

Activated carbon and electric double layer capacitor thereof

An electric double layer capacitor comprises first and second electrodes, each comprising respective first and second carbon materials having distinct pore size distributions. A pore volume ratio of the first carbon material is greater than a pore volume ratio of the second carbon material. The pore volume ratio R is defined as R=V1/V, where V1 is a total volume of pores having a pore size of less than 1 nm, and V is a total volume of pores having a pore size greater than 1 nm.

Ultracapacitor with improved aging performance

A method for fabricating an EDLC includes (a) coating a porous activated carbon material onto current collector sheets to form carbon-based electrodes, (b) drying the carbon-based electrodes, (c) winding or stacking carbon-based electrodes interleaved with separator sheets to fabricate a jelly roll or prismatic electrode assembly, (d) inserting the electrode assembly into a package and forming electrical connections between the electrode assembly and package terminals, (e) filling the package with a liquid electrolyte, and (f) sealing the package. Steps (a)-(f) are performed in an atmosphere having a low moisture content. The atmosphere may be vacuum or purged with dry gas.

A method for forming activated carbon comprises forming a feedstock mixture from a carbon feedstock and a chemical activating agent, and heating the feedstock mixture with microwaves in a plurality of successive heating steps to react the carbon feedstock with the chemical activating agent and form activated carbon. Step-wise heating can be used to efficiently control the microwave activation process.

Microwave energy-assisted, chemical activation of carbon

A method of making a multi-layer current collector comprises forming a first layer from a first formulation over each major surface of a current collector substrate, and forming a second layer from a second formulation over each of the first layers, wherein one of the first formulation and second formulation is a graphite formulation and the other of the first formulation and second formulation is a carbon black formulation.

Dual-layer method of fabricating ultracapacitor current collectors

A method for activating carbon via alkali activation processes includes the introduction of water vapor during the activation phase to control the formation of highly reactive by-products. The method includes heating the mixture of a carbon-containing first material and a alkali-containing second material, introducing water vapor at a first threshold temperature and stopping water vapor introduction at a second threshold temperature. The activated carbon material is suitable for carbon-based electrodes and for use in high energy density devices.
