Abstract
A method of manufacturing lithium-metal nitride including suspending a lithium-metal-oxide-powder (LMOP) within a gaseous mixture, incrementally heating the suspended LMOP to a holding temperature of between 400 and 800 degrees Celsius such that the LMOP reaches the holding temperature, and maintaining the LMOP at the holding temperature for a time period in order for the gaseous mixture and the LMOP to react to form a lithium-metal nitride powder (LMNP).
Claims18
A method of forming a battery electrode comprising:
- suspending a lithium-metal-oxide-powder (LMOP) within a gaseous mixture;
- incrementally heating the suspended LMOP to a holding temperature of between 400 and 800 degrees Celsius such that the LMOP reaches the holding temperature;
- maintaining the LMOP at the holding temperature for a time period in order for the gaseous mixture and the LMOP to react to form a lithium-metal nitride powder (LMNP);
- and
- forming a battery electrode using the LMNP, further comprising degassing the suspended LMOP.

A method of forming a battery electrode comprising:
- suspending a lithium-metal-oxide-powder (LMOP) within a gaseous mixture, wherein suspending the LMOP within the gaseous mixture includes feeding the gaseous mixture to a reaction chamber, wherein the reaction chamber includes an outer wall containing an annular gas path therein surrounding an internal chamber configured to enclose the LMOP;
- feeding the gaseous mixture through a porous media located in a bottom portion of the internal chamber in order to suspend the LMOP;
- incrementally heating the suspended LMOP to a holding temperature of between 400 and 800 degrees Celsius such that the LMOP reaches the holding temperature;
- maintaining the LMOP at the holding temperature for a time period in order for the gaseous mixture and the LMOP to react to form a lithium-metal nitride powder (LMNP);
- degassing the suspended LMOP;
- and
- forming a battery electrode using the LMNP.
