Metal of the negative electrode of the battery

What is a negative electrode in a battery?

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.

Why is metallic lithium considered a negative electrode for a battery?

Metallic lithium is considered to be the ultimate negative electrode for a battery with high energy density due to its high theoretical capacity.

Can aluminum be used as a negative electrode for lithium ion batteries?

Despite a huge loss in capacity due to volume changes in the electrode upon cycling, aluminum appears as a good material as a negative electrode for lithium ion batteries. 1. Introduction Recently, tin has been proposed as a good candidate to replace graphite as a negative electrode for lithium ion cells , , , .

Are metal negative electrodes reversible in lithium ion batteries?

Metal 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.

Which metals can be used as negative electrodes?

Lithium manganese spinel oxide and the olivine LiFePO 4 , are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.
