METHODS FOR MAKING COATED POROUS SEPARATORS AND COATED ELECTRODES FOR LITHIUM BATTERIES

摘要

In an example of a method for coating a lithium battery component, the lithium battery component is provided. The lithium battery component is selected from the group consisting of an uncoated or untreated porous polymer membrane or an uncoated or untreated electrode including a lithium and manganese based active material. A laser arc plasma deposition process, a cathodic arc deposition process, or a pulsed laser deposition process is used to deposit a carbon nanocomposite structure, a metal oxide nanocomposite structure, or a mixed carbon and metal oxide nanocomposite structure i) on a surface of the lithium battery component, or ii) in pores of the lithium battery component, or iii) combinations of i and ii.

1. A method for coating a lithium battery component, the method comprising:
providing the lithium battery component, the lithium battery component being selected from the group consisting of an uncoated or untreated porous polymer membrane or an uncoated or untreated electrode including a lithium and manganese based active material or a sulfur based active material; and using a laser arc plasma deposition process, a cathodic arc deposition process, or a pulsed laser deposition process, depositing a carbon nanocomposite structure, a metal oxide nanocomposite structure, or a mixed carbon and metal oxide nanocomposite structure i) on a surface of the lithium battery component, or ii) in pores of the lithium battery component, or iii) combinations of i and ii.
