Abstract: A continuous hydrothermal process for producing LFP/LMFP cathode materials for lithium-ion batteries. The reactant solutions include: (1) a lithium precursor (LiOH) and a carbon source (15 wt % sucrose); (2) an iron precursor (FeSO4) and a phosphorus precursor (H3PO4); and in the case of LMFP, a manganese precursor (MnSO4) and a surfactant in solution 2. Reactant solutions are fed into a series of one or more continuous stirred tank reactors (CSTRs) at a constant flowrate. Active LFP/LMFP flows out of the CSTRs and into a collection tank, where it is cooled and depressurized. The product flows into a slurry tank, then a centrifugal separator to remove aqueous waste. The LFP/LMFP is transferred to a continuous rotary kiln for drying and sintering, and the carbon coating forms. The disclosed processes produce LFP/LMFP with small average particle size, high purity, high capacity, and high yield without any ball-milling or sieving steps.

Abstract: A wearable breathing apparatus includes a thermal capacitor that a user inhales and exhales through. Inhaled air is cooled as it passes through the thermal capacitor, and exhaled air cools the material of the thermal capacitor for the next breathing cycle. The breathing apparatus may be used by a firefighter, for example, as a lightweight apparatus to enable the firefighter to safely breathe dangerously heated air, for example while in a fire shelter, that may otherwise cause injury to the user. The breathing apparatus advantageously does not require external power for cooling. The thermal capacitor may also be used as a part of a rebreather that uses a scrubber that removes carbon dioxide from exhaled air, for rebreathing. Further, the thermal capacitor may be used for other purposes, such as in recirculation of building air.
