Battery breaking technology

Battery breaking technologies use wet classification to separate the components of cmshed batteries. Before cmshing, the sulfuric acid is drained from the batteries. The sulfuric acid is collected and stored for use at a later stage in the process, or it may be upgraded by a solvent extraction process for reuse in battery acid. 

The Ginatta process also uses a fluorborate electrolyte and is based on the leaching of battery pastes which have been desulfurised with ammonium carbonate. The electrowinning process is licensed to MA Industries, who promote it in conjunction with their battery breaking technology (Ginatta, 1984). 

PEAT, Inc., has developed the thermal destruction and recovery (TDR) system for the treatment of medical, hazardous, and radioactive wastes. An electronic plasma heating system is used to break down wastes into three phases. The ceramic, metal, and off-gas phases can aU be used as commercial products. The technology has been evaluated in treatability studies on infectious medical waste. Department of Defense (DOD) ammunition and energetic materials, U.S. Department of Energy (DOE) weapon components, ash, electronic scrap, batteries, asbestos, and organic compounds. 

For high-volume automotive-type batteries, the fabrication process was substantially modified with the introduction of the PE separator and its two unique properties flexibility and weldability. Unlike previous separators, the PE separator could be wound onto a roll and could be completely wrapped around the plate without breaking and cracking. Additionally, the PE separator was weldable unto itself either by sonic, mechanical, or heat welding. These two properties opened up the opportunity for further assembly optimization of which the equipment suppliers soon advanced the technology to meet the need [34]. The assanbly equipment automatically wraps a separator around the bottom of the PE separator and then mechanically seals the sides to create a three-sided pocket around the plate. This pocket minimizes the potential for bottom and side shorts.
