Lithium-ion Battery Components

Lithium-ion batteries are composed of several components, each of which plays an important role in the battery’s function. The most common components of a lithium-ion battery include cathodes, anodes, separators, and electrolyte solutions.

The cathode is a metal oxide material, and its purpose is to store and release electrons when the battery is in use. The anode is the opposite of the cathode, and it absorbs electrons during the battery’s charge cycle. When the battery is discharged, the cathode releases electrons and the anode absorbs them.

Separators are also an important component of lithium-ion batteries. These thin membranes separate the cathode and anode and prevent short circuits. The electrolyte solution is made up of various salts, and it allows ions to move freely between the cathode and anode.

It is important to understand how these components work together to create a working lithium-ion battery. When the battery is charged, the lithium ions move from the anode and into the cathode. During the discharge process, the ions then move back to the anode. This process is what creates the electric current that is used to power the device.

Understanding the Lifecycle of Li-ion Batteries

When it comes to the lifecycle of Lithium-ion batteries, there are several stages that it goes through. Knowing about these stages means you can understand how the batteries are produced, used, and eventually disposed of.

There are six primary stages associated with a Li-ion battery’s life cycle. These include:

• Manufacturing: Raw materials such as lithium and cobalt are mined to produce the components of the battery and then assembled.
• Distribution: This is when batteries are sent out and distributed to wholesalers and retailers.
• Use: This is the stage where the battery is put into use in a device or vehicle.
• Collection: Li-ion batteries reach the end of their useful life and are collected for recycling or disposal.
• Recycling: If the battery is suitable, it can be recycled and the raw materials recovered and put to use in other products.
• Disposal: If the battery is not suitable for recycling, it must be carefully and safely disposed of.

Each stage of a Li-ion battery’s life cycle has potential environmental implications and impacts. To ensure Li-ion batteries are used responsibly and these impacts are minimized, we all need to be aware of the different stages of the life cycle and how each can affect the environment.

The operation of chemical power sources is based on the interaction of metals and liquids, a reversible reaction that occurs when the positive and negative plates close contact. Lead-acid batteries, as the name implies, consist of lead and acid, where the positively charged plates are lead and the negatively charged plates are lead oxide. If a light bulb is connected to the two plates, the circuit closes and an electric current (movement of electrons) is generated, and a chemical reaction occurs inside the cell. In particular, the battery plates corrode and lead is coated with lead sulphate. Thus, a lead sulphate deposit will form on all plates as the battery discharges. When the battery is fully discharged, the plates are coated with the same metal, lead sulphate, and have almost the same charge relative to the liquid, so the battery voltage will be very low.

If a battery charger is connected to the appropriate terminals and switched on, the current will flow in the acid in the opposite direction. The current will cause a chemical reaction, the acid molecules will split and through this reaction lead sulphate will be removed from the positive and negative plates of the battery. In the final stage of the charging process, the plates will have a pristine appearance: lead and lead oxide, allowing them to be charged differently again, i.e. the battery will be fully charged.

In practice, however, things look a little different and the electrode plates are not completely cleaned, so the batteries have a certain life span, upon reaching which the capacity is reduced to 80-70% of the original capacity.
