As battery technology continues to improve, Electric Vehicles (EVs) are becoming more and more popular.

One key factor in the success of EV’s is the battery that powers them.

There are many different types of batteries that can be used in EV’s, but one of the most popular is the lithium ion battery.

One area of improvement is in the development of energy dense lithium ion batteries.

Lithium ion batteries are known for their high energy density, which means that they can store a lot of energy in a small space.

These batteries have the potential to increase the range of EV’s while reducing weight and cost.

For now, lithium ion batteries are a good option, but drivers should be aware of both the advantages and disadvantages.

The disadvantages

There are some disadvantages to using lithium ion batteries in EV’s,

One is that they are expensive to produce, which means that the cost of EV’s can be high.

Another disadvantage, is that they can be dangerous if they are not used correctly, as they can catch fire.

If the battery is punctured, it can explode and the batteries are very sensitive to high temperatures.

Also, if the battery is not properly disposed of, it can release toxic chemicals into the environment.

These types of batteries have a very short lifespan of around 2 to 3 years from the manufacturing date, even if the battery is not in use.

This means that there is a big possibility that it will be costly for drivers in the long run.

The advantages

Overall, lithium ion batteries are a good option for powering EV’s.

They have a high energy density, which makes them ideal for EV’s.

However, they are expensive to produce, which can make EV’s costly.

Another advantage of these types of batteries are that, they do not suffer from “memory effect.”

This means that they can be charged and discharged as needed without losing capacity.

Lithium ion batteries have a longer lifespan than nickel-based batteries.

They can also endure more charge and discharge cycles.

Also when charging the battery the rate of charge loss is a lot less than other types of batteries.

The two types of Lithium Batteries

The two types of lithium batteries are the lithium-cobalt oxide battery and the lithium-iron phosphate battery.

The first is more energy-dense but more costly, while the other is less energy-dense but cheaper.

There are pros and cons to each type of battery, and it is important to weigh those factors when deciding which type of EV to purchase.

Lithium-cobalt oxide battery

The lithium-cobalt oxide battery is the type of EV battery most widely used today.

The lithium-cobalt oxide battery uses lithium ions to store energy, and these are intercalated into the host lattice.

The most positive electrode is made of cobalt oxide (CoO2) and the negative electrode is made of carbon, usually in the form of graphite.

Lithium-iron phosphate battery

Lithium-iron phosphate battery uses lithium ions to move from the negative electrode to the positive electrode during discharge and vice versa during charging.

This type of battery has good thermal stability and is not prone to explosions or fires.

Lithium-iron phosphate batteries are used in Hybrid and Electric Vehicles.

Lithium-ion batteries are lightweight, have a high energy density, and do not require frequent maintenance.

Tesla Electric Vehicles uses Lithium-iron phosphate battery and it has been said that they charge to 100% every time.

This type of battery is known to have one of the highest energy densities, making it a good choice for Electric Vehicles.

However, it is also one of the most expensive types of batteries.

The most significant breakthrough that electric manufacturers are striving for is the solid-state cell, which is named for its solid electrolyte, or the conducting substance between the cathode and anode that is generally liquid or polymer in today’s cells.

Solid-state batteries are expected to be more energy-dense, safer, and most likely replace existing lithium-ion technologies.

However, they won’t appear on production cars until at the very least 2025, and even then, only in pricey, low-production vehicles.

It has been said that, Toyota is investing a significant amount of effort into making solid-state cells feasible for mass production and intend to launch by the mid decade.

It has also been said that, Hybrid vehicles are more than likely to get these type of batteries first.

Want more knowledge about EV’s or Hybrid’s?

Here at MTC, we offer a variety of courses that can give you the information you need about electric and hybrid vehicles.

Hybrid Training Course, Level 1 – Raise Awareness
Hybrid/ EV Training Course, Level 2 – Light Vehicles 
Hybrid Training Course, Level 2 – Buses 
Hybrid Training Course, Level 2 – HGV’s
Hybrid Training Course Level 3 – Cars

The Level 1 Hybrid and Electric Training Course, is to raise awareness of Hybrid and Electric Vehicles. This course is aimed at anyone that may come into contact with Hybrid and Electric Vehicles.

Level 2 Hybrid and Electric Light Vehicle Training Course, Level 2 HGV Training Course and Level 2 Buses Training Course. The Level 2 course is aimed at mechanics and car valeters.

The Level 3 Hybrid and Electric Training Course, is aimed at technicians and mechanics.

Information about our Hybrid Courses and what we will cover:

  • Safe system shut down and recommissioning.
  • Methods of safe component and system test and measurement.
  • Using and interpreting vehicle wiring diagrams & tech data for speedy and efficient repairs.
  • Hybrid propulsion and energy generation systems.
  • Brush less 3 Phase Motor form and function.
  • DC and AC (3 phase) Control Systems.
  • Using OEM, Pass-thru and Aftermarket Scan Tools for in vehicle system and component diagnosis.
  • How to work safely on hybrid and related vehicle systems.
  • How to carry out maintenance and repair activities when working on Hybrid vehicles.
  • Construction and function of battery modules and related components

It is anticipated that Level 3 will be the minimum requirement in the future.

Best practice dictates that each technical staff member should be qualified to at least level 2 (service technician).

Diagnostic technicians should be qualified to level 3 (for fault diagnosis and removal, test and refit of high voltage systems).

Our trainers are experienced in the field and can provide you with all the knowledge you need.
