Materials of Tin-Based Negative Electrode of Lithium-Ion Battery

Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious decrease in capacity. An

Guide to Battery Anode, Cathode, Positive, Negative

Cathodes and Anodes are electrodes of any battery or electrochemical cell. These help in the flow of electrical charges inside the battery. Moreover, the cathode has a positive charge, where reduction occurs (receives electrons). In contrast, the anode has a negative charge, where oxidation occurs (loss of electrons) and electricity is produced.

6 FAQs about [What material is the negative electrode of the battery called]

What is a negative electrode in a lead-acid battery?

In lead-acid batteries, the anode is negative during discharge. The sponge lead (Pb) acts as this electrode, while lead dioxide (PbO2) is the cathode. The oxidation reaction at the anode can be expressed as: Pb + SO₄²⁻ → PbSO₄ + 2e⁻ This indicates that lead loses electrons (is oxidized), confirming its role as a negative electrode.

Which electrode is negative when charging a lithium ion battery?

In lithium-ion batteries, the anode is also negative when discharging. The primary material used for this electrode is graphite. Lithium ions move from cathode to anode during charging and intercalate into graphite layers. The reaction at the anode can be represented as: Li⁺ + e⁻ + C → LiC₆

Is a cathode a positive or negative electrode?

The positive electrode has a higher potential than the negative electrode. So, when the battery discharges, the cathode acts as a positive, and the anode is negative. Is the cathode negative or positive? Similarly, during the charging of the battery, the anode is considered a positive electrode.

What is a negative electrode in a battery?

When discharging, it acts as a negative electrode. Lead-Acid Batteries: Lead dioxide (PbO2) is the positive terminal during discharge, while sponge lead (Pb) is the negative terminal. Each type of battery has its unique chemistry that influences how it operates, and its components interact.

Does lithium battery anode have a negative charge?

While the lithium-ion anode is present opposite to the cathode, it has a negative charge. Hence, it undergoes an oxidation reaction during the charging and discharging of the battery. What Is Lithium Battery Anode Materials?

Is a battery anode or a cathode?

During discharge the positive is a cathode, the negative is an anode. During charge the positive is an anode, the negative is a cathode. Texts describing battery anodes or cathodes certainly implicitly consider the case of the discharge. Let us not hesitate to write, paraphrasing Rutherford, implicit is nothing but poor explicit.
