  • Patent number: 9339784
    Abstract: Provided are methods and apparatus for forming electrode active materials for electrochemical cells. These materials include a metal (e.g., iron, cobalt), lithium, and fluorine and are produced using plasma synthesis or, more specifically, non-equilibrium plasma synthesis. A metal containing material, organometallic lithium containing material, and fluorine-containing material are provided into a flow reactor, mixed, and exposed to the electrical energy generating plasma. The plasma generation enhances reaction between the provided materials and forms nanoparticles of the electrode active materials. The nanoparticles may have a mean size of 1-30 nanometers and may have a core-shell structure. The core may be formed by metal, while the shell may include lithium fluoride. A carbon shell may be disposed over the lithium fluoride shell. The nanoparticles are collected and may be used to form an electrochemical cell.

  • Patent number: 9343734
    Abstract: The present invention provides a multi-dimensional carbon active compound composite comprising a first carbon material, a second carbon material, an active compound, and further a seed material. This composite is capable of storing faradic or non-faradic charges. The produced multi-dimensional carbon can significantly inhibit the aggregation and disintegration of active compounds. Stacked carbon structure also formed a 3-D framework with high electron conductivity, which increases the rate capability of electrode. The green and simple synthesis process has a great potential for mass production. This green energy storage material can be widely applied to lithium secondary ion battery, supercapacitor, and lithium-air battery electrodes.
