AI Customer ServiceMetal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions.
It should be noted that the potential applicability of this anode material in commercial lithium-ion batteries requires a careful selection of the cathode material with sufficiently high voltage, e.g. by using 5 V cathodes LiNi 0.5 Mn 1.5 O 4 as positive electrode.
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 .
In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
The first lithium-ion rechargeable battery was developed in 1991. Japan’s Sony Corporation used a carbon material as the negative electrode and a lithium cobalt composite oxide as the positive electrode. Subsequently, lithium-ion batteries revolutionized consumer electronics.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
