Learn MoreThe electrodes in lithium ion batteries are made of lithium-ion alloys that are conductive. The anode is the material that receives the lithium ions, and the cathode is the material that collects the lithium ions. The electrodes are typically formed of metal, graphite, and lithium.
Si/CNT nano-network coated on a copper substrate served as the negative electrode in the Li-ion battery. Li foil was used as the counter electrode, and polypropylene served as the separator between the negative and positive electrodes. The electrolyte was 1 M LiPF6 in ethylene carbonate (EC)/dimethyl carbonate (DMC) (1:1 by volume).
In lithium ion batteries, the most common types of electrodes use nickel-manganese-cobalt-nickel-sulfur alloys. However, researchers are working on increasing the combination to up to 80% while keeping other metals to a minimum.
Since the cracking of carbon materials when used as negative electrodes in lithium batteries is very small, several allotropes of carbon can be used, including amorphous carbon, hard carbon, graphite, carbon nanofibers, multi-walled carbon nanotubes (MWNT), and graphene .
The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
Simultaneously, the term “lithium-ion” was used to describe the batteries using a carbon-based material as the anode that inserts lithium at a low voltage during the charge of the cell, and Li 1−x CoO 2 as cathode material. Larger capacities and cell voltages than in the first generation were obtained (Fig. 1).
