|20150259208||Method of Making Active Materials for Use in Secondary Electrochemical Cells - The present invention provides a method for producing lithium iron phosphate or lithium iron mixed metal phosphate. The method comprises using waste pickling liquor as a starting material wherein the waste pickling liquor is the source of the iron ions in such phosphates. The waste pickling liquor is mixed with lithium hydrogen phosphate, and optionally a source of at least one metal ion. The precipitate is then dried or filtered and calcined to produce a lithium iron phosphate or a lithium iron mixed metal phosphate.||09-17-2015|

|20130214788||Battery Insulation Resistance Measurement Methods, Insulation Resistance Measurement Methods, Insulation Resistance Determination Apparatuses, And Articles Of Manufacture - Battery insulation resistance measurement methods, insulation resistance measurement methods, insulation resistance determination apparatuses, and articles of manufacture are described. According to one aspect, a battery insulation resistance measurement method includes determining a voltage of a battery, determining a voltage of a first terminal of the battery with respect to a ground reference, determining a voltage of a second terminal of the battery with respect to the ground reference, and using the voltages of the battery, the first terminal and the second terminal, determining an insulation resistance of the battery with respect to the ground reference.||08-22-2013|
|20090068080||Method of Making Active Materials For Use in Secondary Electrochemical Cells - The present invention provides for the two step preparation of lithium vanadium phosphate by pre-treatment of a mixture of precursor materials via high pressure at relatively low temperatures in water (hydrothermal pretreatment) and then calcining such hydrothermally pretreated precursors at relatively high temperatures for a period of time sufficient to produce lithium vanadium phosphate. The lithium vanadium phosphate so produced finds use in producing electrodes for electrochemical cells.||03-12-2009|
