Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Singapore Application No. 10201909125Y filed on 30 September 2019, the contents of which are hereby incorporated by reference in their entirety for all purposes. technical field [0003] Various aspects of the disclosure relate to electrodes. Various aspects of the disclosure relate to electrochemical cells. Various aspects of the present disclosure relate to a method of forming an electrode. Various aspects of the disclosure relate to a method of forming an electrochemical cell. Background technique [0004] Commercial lithium-ion batteries use anodes containing natural and synthetic graphites that intercalate lithium (Li). The resulting graphite intercalation compound can be expressed as Li x C 6 , where x is usually less than 1. The maximum amount of lithium ions that can be reversibly intercalated in the interstices between graphene planes of perfectly crysta...
