What Is A Lithium-Ion Battery

Before we dive deep into the topic, let us answer the question: what is a lithium-ion battery? Lithium-ion batteries consist of single or multiple Li-ion cells and a circuit board. Unlike other batteries, Li-ion batteries have high energy densities and can deliver up to 3.65V.

A Li-ion cell consists of four elements: a cathode, an anode, a separator, and an electrolytic solution. A lithium-ion battery assembles more than one cell integrated into a single module. The module combined with a BMS (Battery Management System) constitutes the battery.

How A Lithium-Ion Battery Works

As mentioned above, the lithium-ion battery comprises anode, cathode, separator, and two electrodes. The remaining space of the battery is filled with an electrolyte. Below we reveal "how does a lithium-ion battery work."

During the charging process, the charger passes current to the lithium-ion battery. The lithium ions start moving through the separator from the cathode to the anode. The electrical difference between the two electrodes charges the battery.

Unlike charging, the discharge circuit is formed between the anode and cathode in discharging. In this case, the lithium ions are stored in the anode, which then moves to the cathode. Lastly, the energy is used, causing the battery to discharge.

Let's now understand how electricity flows in a lithium-ion cell. The cell also consists of an anode, a cathode, an electrolyte medium, and a separator. In the lithium-ion battery, an ether-based solution acts as an electrolyte.

This sophisticated solution allows lithium-ion to pass while stopping the electrons from passing through the microscopic holes in the separator. The lithium ions move and meet with their long-lost electrons in the cathode to create a reduction reaction.

The Pros and Cons of Lithium-Ion Battery

Lithium-ion batteries have several advantages compared to other batteries, such as nickel-cadmium or nickel-metal-hydride. But how to charge a lithium-ion battery? These lithium batteries can be charged using solar panels, making them a clean and green solution. Despite their technological promise, there are a few things that one must keep in mind with regard to safety.

Pros

  • Lithium-ion batteries have a higher energy and power density.
  • They are rechargeable with minimal memory effect.
  • They charge faster and can hold power for a long time.
  • Li-ion battery has a low self-discharge (less than NiMh and NiCd)
  • These batteries have a long lifecycle and extended shelf-life

Cons

  • The Li-ion battery requires a protection circuit, so there is no thermal runaway.
  • It can degrade at high temperatures and high voltage.

The Usage of Lithium-Ion Batteries

Modern lithium-ion batteries are used for a wide range of applications. Here are some common uses of Li-ion batteries in day-to-day life.

  • Electric Vehicles (EVs): These vehicles generally require batteries or cells with long life, quick charging ability, and stability. For this reason, automakers use lithium-ion batteries.
  • Portable Electronics: Products such as tablets, laptops, smartphones, and other electronic devices use Li-ion batteries with high power density.
  • Medical Devices: Portable medical equipment like hearing aids, pacemakers, etc., use Li-ion batteries as they have longer lifespans and low self-discharge.

The Types of Lithium-Ion Batteries

Different types of lithium batteries use unique active materials and have their benefits and drawbacks.

Lithium Cobalt Oxide (LCO)

LCO batteries have higher specific energy but low specific power. They are common in small portable electronics, like tablets, phones, etc. However, they are expensive due to the high cost of cobalt.

Lithium-ion Manganese Oxide (LMO)

These LMO batteries use lithium manganese oxide as a cathode. They deliver higher currents and better thermal stability than LCO batteries. The main downside of LMO is its short lifespan. 

Lithium Iron Phosphate (LFP)

Lithium iron phosphate battery, or LiFePO4, uses phosphate as a cathode and graphite carbon electrode as an anode. They have a long lifecycle with good electrochemical performance and thermal stability. However, they have relatively low specific energy.

Lithium Nickel Manganese Cobalt Oxide (NMC)

NMC batteries combine three main elements as cathode: nickel, cobalt, and manganese. They have a longer lifespan and high energy density at low cost. The only drawback of NMC is that they have a slightly lower voltage than most cobalt-based batteries.

Lithium Nickel Cobalt Aluminium Oxide (NCA)

The NCA batteries offer high specific energy and a long lifecycle. They can deliver a high amount of current for long periods. However, these batteries are less safe and more expensive than most other lithium technologies.

Lithium Titanate (LTO)

Lithium titanate batteries are generally safer and have a long lifespan. These batteries can charge faster than other types available in the list. You can usually find these batteries in EVs, charging stations, solar street lights, etc. However, they are expensive and offer low energy density.
