Abstract
A novel lithium battery cathode, a lithium ion battery using the same and processes and preparation thereof are disclosed. The battery cathode is formed by force spinning. Fiber spinning allows for the formation of core-shell materials using material chemistries that would be incompatible with prior spinning techniques. A fiber spinning apparatus for forming a coated fiber and a method of forming a coated fiber are also disclosed.
Claims7
A method of forming a cathode, comprising:
- forming a plurality of precursor fibers by fiber spinning a fiber comprising a core and shell by a spinneret;
- and
- calcinating the plurality of precursor fibers to form the cathode;
- wherein fiber spinning is performed by rotating the spinneret at a rotational speed between about 3,000 and about 10,000 rpm.
