1. A method of producing a lithium-containing non-amorphous hard-carbon composite from a furan-ring containing compound, comprising:
a. mixing an insoluble lithium compound and an acidic catalyst with a furan-ring containing compound to form a mixture, wherein the furan-ring compound is a 5 membered ring with 4 carbon atoms and 1 oxygen atom;
b. soaking the mixture at room temperature and further heating the mixture between 25° C. and 200° C. to form a solid-polymer/lithium-containing composite; and
c. heating the solid-polymer/lithium-containing composite between 200° C. to 1100° C. under an inert atmosphere, to carbonize the solid-polymer/lithium-containing composite and make the lithium-containing non-amorphous hard carbon.
