What is a “lithium battery”? How does it work?

lithium batteries

The working principle of lithium batteries is also the principle of charging and discharging of lithium batteries, which is the process of embedding and deintercalation of lithium ions. When charging, lithium ions are generated at the positive electrode of the battery, and these lithium ions move to the negative electrode under the action of the electrolyte. When the battery is discharged, the lithium ions embedded in the carbon layer of the negative electrode fall off and then return to the positive electrode. In order to make it easier for everyone to understand the working principle of lithium batteries, here I will give you some popular science.

1: The meaning of lithium battery

Lithium battery is a battery that uses non-aqueous electrolyte and lithium metal or lithium alloy as positive and negative electrode materials. Because the chemical properties of lithium metal are relatively active, it is often used in industry, environmental protection, etc., and it is also the most mainstream battery type at the moment.

Lithium metal batteries usually use manganese dioxide as the positive electrode, metallic lithium or its alloy as the negative electrode, and use non-aqueous electrolyte for composition. The discharge reaction of lithium battery is actually the chemical expression of Li+MnO2=LiMnO2.Lithium batteries have the characteristics of extremely low self-discharge rate, stable discharge voltage, and long service life, so they are often used in the manufacturing of digital products, watches, and other processes.

2: Working principle of lithium battery

Lithium batteries are secondary batteries compose of two compounds that can reversibly intercalate and deintercalate lithium ions as positive and negative electrodes. This also shows that lithium in lithium batteries always appears in the form of lithium ions. And will not appear in the form of metallic lithium.

Lithium battery charging process:

When a lithium battery is charged, lithium ions are generated at the positive electrode of the battery, and the lithium ions are transported to the negative electrode through the electrolyte ; and the carbon structure of the negative electrode naturally forms many small pores, and the lithium ions arriving at the negative electrode are wrapped in tiny pores in the carbon layer. , the more lithium ions are packed in, the greater the charging capacity will be.

The discharge process of lithium battery:

When a lithium battery is discharged, the lithium ions buried in the carbon layer of the negative electrode will detach and return to the positive electrode. If there are more lithium ions after detachment, the higher the current of the battery, the greater the capacity.
