Abstract: A method of doping elements (particularly those that do not have stable divalent oxidation states) into lithium rich metal oxides useful in lithium ion batteries is comprised of the following steps. A dopant metal is dissolved in a liquid, which includes being present as a colloid, to form a solution. The solution is added to a particulate lithium rich metal oxide precursor while agitating said precursor to form a mixture. The solution is added in an amount that is at most that amount which would make the mixture a paste. The liquid is removed to form a doped lithium rich metal oxide precursor. A source of lithium is added. The doped lithium rich metal oxide precursor is heated to form the lithium rich metal oxide.

Abstract: An improved method of making a cathode for use in a lithium ion battery is comprised of mixing a lithium metal oxide and lithium metal phosphate in a solvent, where both of these are comprised of primary particles that have been agglomerated into secondary particles of particular size and mixing is insufficient to break up the particles of the lithium metal phosphate, coating the mixture of step (A) on to a metal foil and removing the solvent to form the cathode. The lithium metal oxide is also desirably not broken either. The cathode may be one that has lithium metal oxide and a particular lithium metal phosphate wherein the majority of the metal is Mn.

Abstract: A numerical controller acquires state information (machine condition) such as the current temperature of a drive unit to determine whether a machining operation based on a machining program can be started or not by comparing the state information with a machine condition history recorded in a recording unit. If determined that the machining operation can be started, a machining operation start command is output and if determined that the machining operation cannot be started, the machine condition is monitored to withhold outputting of the machining operation start command until the machine condition allowing to start the machining operation based on the machining program appears.
