Lithium Battery

Batteries that have lithium as their anode are called lithium batteries. The charge moves from anode to cathode during the discharge and the charge moves from cathode to anode during charging. Lithium batteries were introduced way back in the 1980s -1990s. These batteries have completely revolutionized to the portable electronics market such as cellular telephones and laptop computers.

What is a Lithium Battery?

Among the developed batteries, lithium-ion batteries (LIBs) have received the most attention, and have become increasingly important in recent years. Compared with other batteries, LIBs offer high energy density, high discharge power, high coulombic efficiencies, and long service life. These characteristics have facilitated a remarkable advance of LIBs in many frontiers, including electric vehicles, portable and flexible electronics, and stationary applications like BESS.

What are the major components of a Lithium Battery?

A battery consists of several key components: the anode, cathode, separator, electrolyte, and two current collectors (one positive and one negative).

1. Anode and Cathode: These are the electrodes where lithium ions are stored. The anode is typically the negative electrode, while the cathode is the positive electrode.

2. Electrolyte: This is a conductive medium that facilitates the movement of lithium ions between the anode and the cathode. It is usually a liquid or gel-like substance.

3. Separator: Positioned between the anode and cathode, the separator prevents direct electrical contact between them while allowing the passage of lithium ions through it.

4. Current Collectors: These are conductive materials attached to the anode and cathode that  collect and transfer electrical current to and from the external circuit.

How Lithium Battery Works?

Let me explain the basic construction of a battery. Lithium Battery is one of the rechargeable batteries. The working and function of a lithium battery is same as any other battery. The battery is a combination of cells. First, we need to know what is a cell. The cell is a closed entity that has 3 components: an Anode, a Cathode, and a Separator. Anode means positive (+) terminals, Cathode means negative (-) terminal, and Separator is a porous membrane that physically separates anode and cathode.

According to our needs, we can connect these cells either in series by connecting the anode of one cell to the cathode of another cell and so on or we can connect the cells in parallel by connecting the anode of all the cells and cathode of all the cell. 

Power is defined as the product of voltage and current (P=VxI) rating. This power can be used by connecting a load to the battery and this complete circuit is known as an external circuit. This circuit can either be a DC solution whether we are using a DC load or whether we are using an AC load we can connect the battery using an inverter of a specific rating.

When the load is connected the current flows from the anode to the cathode i.e. positive to negative terminal. Whereas, while charging the polarity is reversed, and the current flows from cathode to anode.

How to make a battery?

But have you ever stopped to wonder what's inside these devices that allow us to send emojis, drive around town and so much more? If so, check out the Advanced Battery Facility. To know how do all these parts get assembled?

How is a Lithium Battery different from a Lead Acid Battery?

Lead-acid batteries use plates of lead and lead oxide in a sulfuric acid solution. Commonly used in cars and trucks these batteries are rechargeable. Lead-acid batteries are less expensive, but they have a shorter lifespan and require regular maintenance. Lithium batteries are much more expensive upfront, but they are maintenance-free and have a longer lifespan. The leading popularity of lead-acid batteries is because they are not only dependable but are also very cheap. However, this technology is old and technicians prefer lithium batteries to better suit the purpose, given its higher efficiencies and densities. Lithium batteries are more efficient and charge faster when compared to lead-acid batteries. Lithium is a premium battery technology with a longer lifespan and higher efficiency.
