20110272331 | PROCESS FOR THE SEPARATION OF MATERIALS FROM RECYCLED ELECTROCHEMICAL CELLS AND BATTERIES - Materials in battery and electrochemical cells are separated in a form suitable for recycling by employing froth flotation techniques. Bulk materials, such as casings, are removed from converted battery scrap and the resultant pulp is subjected to froth flotation. Froth flotation agents, including frothers, collectors and/or depressants, are used to manipulate the hydrophilic and hydrophobic nature of the materials in the scrap. Hydrophobic materials are entrained in the air bubbles of the froth and float out of the froth flotation vessel while those that are hydrophilic remain in the vessel, thereby separating battery grid materials without resort to pyrometallurgical, energy intensive or other environmentally undesirable processes. | 11-10-2011 |
20120006679 | ELECTROCHEMICAL ANODES HAVING FRICTION STIR WELDED JOINTS AND METHODS OF MANUFACTURING SUCH ANODES - An electrochemical anode is formed using friction stir welded (FSW) joints. A FSW joint may be formed between the bus bar and anode sheet or the lead encapsulation and anode sheet. The FSW joints may also comprise fillet and butt joints. FSW joints may also be utilized to seal the ends of the electrochemical anodes to prevent corrosion. | 01-12-2012 |
20120118758 | ELECTRODES MADE USING SURFACING TECHNIQUE AND METHOD OF MANUFACTURING THE SAME - An electrode is formed using a sanding mechanism to condition the surface of the electrode for electrochemical purposes. Hazardous particles emitted during sanding are captured using jetted liquid, and may be recycled for later use. The sanded surface provides increased electrode lifespan and lead oxide adherence. | 05-17-2012 |
20120222550 | WET ELECTROSTATIC PRECIPITATOR AND RELATED METHODS - An emissions reduction stack comprises a conditioning section, collector section utilizing a Wet Electrostatic Precipitator (WESP), and output section. A chemically active aqueous stream is introduced into an incoming process stream in order to saturate the stream and produce a fog stream wherein water is condensed on the surface of particulates. The process of condensation increases the efficiency of the particulate filtration process conducted by the WESP. | 09-06-2012 |
20130256198 | MAGNETIC SEPARATION OF ELECTROCHEMICAL CELL MATERIALS - A process and system for the separation of materials from electrochemical cells is disclosed. Electrode materials are removed from electrochemical cells and separated into constituent active materials using magnetic separation. | 10-03-2013 |
20140291210 | RECYCLING ELECTROCHEMICAL CELLS AND BATTERIES - Processes for separating and recycling battery and electrochemical cell materials are disclosed. | 10-02-2014 |
20150040759 | WET ELECTROSTATIC PRECIPITATOR AND RELATED METHODS - An emissions reduction stack includes a conditioning section, collector section utilizing a Wet Electrostatic Precipitator (WESP), and output section. A chemically active aqueous stream is introduced into an incoming process stream in order to saturate the stream and produce a fog stream wherein water is condensed on the surface of particulates.
