Pink Microcrystalline Powder (IMAGE) Technical University of Munich (TUM) Caption Dr. Jennifer Ludwig at the Technical University of Munich (TUM) has developed a process, that allows a fast, simple, and cost-effective production of nanocrystalline lithium cobalt phosphate crystals. Compared to standard lithium iron phosphate this material improves the energy density of lithium-ion batteries from about 600 to 800 watt hours per kilogram.
