Electric Vehicles : Are they really safe for the environment ?

Electric vehicles (EVs) are vehicles that are powered by electric motors and batteries,

rather than by internal combustion engines (ICEs) that run on gasoline or diesel. EVs have several advantages over ICE vehicles,

including lower operating costs, reduced emissions, and improved energy efficiency.

How EVs work

Electric vehicles (EVs) work by using electric motors, rather than internal combustion engines (ICEs), to power the vehicle. The electricity to power the motor is stored in batteries, which are recharged through various means.

The heart of an EV is its electric motor, which converts electrical energy into mechanical energy to power the vehicle's wheels. The electric motor is typically more efficient than an ICE, because it does not generate waste heat and can convert a higher percentage of the electrical energy it receives into useful work.

The electricity to power the motor is stored in batteries, which are rechargeable. There are several types of batteries that can be used in EVs, including lead-acid, nickel-cadmium, nickel-metal-hydride and Lithium-ion batteries. Lithium-ion batteries are the most common type of battery used in EVs today, because they are relatively lightweight, have a high energy density, and can be recharged quickly.

To charge the batteries, EVs can be plugged into an electrical outlet or charging station. There are several types of charging options available, including level 1 charging, which uses a standard household electrical outlet and can take several hours to charge the batteries; level 2 charging, which uses a dedicated charging station and can take several hours to charge the batteries; and level 3 charging, also known as DC fast charging, which can charge the batteries to 80% in under 30 minutes.

Once the batteries are charged, the electricity is sent to the electric motor, which powers the vehicle's wheels. The electric motor is controlled by an electronic controller, which regulates the flow of electricity to the motor. This allows the driver to control the speed and acceleration of the vehicle.

EVs also have regenerative braking systems, which convert the kinetic energy of the vehicle into electrical energy and store it back into the batteries during braking. This means that the vehicle can recover some of the energy it loses during braking and use it to power the vehicle, making it more energy efficient.

Composition of Lithium-ion Batteries : Cobalt

Cobalt is a metal that is commonly used as a key component in the cathodes of lithium-ion batteries. The cathode of a lithium-ion battery is the electrode where lithium ions flow into the battery during charging.

Cobalt is used in lithium-ion battery cathodes because it has a unique combination of properties that make it well-suited for use in batteries. It has a high energy density and a relatively low thermal stability, which means that it can store a large amount of energy while remaining relatively stable at high temperatures. Additionally, cobalt has a relatively low electronic conductivity, which means that it can slow down the movement of lithium ions through the cathode, making the battery more stable and less likely to overheat.

Cobalt Mining: Impact on Environment

Cobalt mining can have a number of harmful effects on the environment and local communities.

One of the main concerns with cobalt mining is the impact it can have on water resources. Cobalt is often found in areas with limited water resources, and the mining process can consume large amounts of water. This can lead to water scarcity for local communities and can also negatively impact local ecosystems.

Another concern with cobalt mining is the impact on the local environment and wildlife. The mining process can involve the removal of large amounts of vegetation and can also lead to the creation of new roads and infrastructure. This can lead to the fragmentation of natural habitats and can negatively impact local wildlife.

Cobalt mining can also have negative social impacts on local communities. The mining process can lead to the displacement of local residents, and can also lead to a loss of traditional livelihoods. Additionally, the influx of workers and the development of new infrastructure can lead to increased competition for resources and can also lead to social tensions.

The mining of cobalt is also associated with human rights violation, particularly in the Democratic Republic of Congo (DRC) which is the world's largest cobalt producer. The DRC has a long history of political instability and armed conflict, and the mining of cobalt has been linked to human rights abuses, including the use of child labor and poor working conditions. This is partly because cobalt mining is often done by artisanal miners, who work in small, independent mines, and are not subject to the same labor and safety standards as larger, commercial mines.

Overall, cobalt mining can have a number of negative impacts on the environment and local communities.

It is important for cobalt mining to be conducted in a sustainable and responsible manner, with consideration for the potential impacts on

the environment and local communities. This can include the use of new technologies and approaches to minimize the environmental impact of the mining process,

as well as the implementation of social and environmental safeguards to protect the rights and well-being of local communities.

From the surface , it may look like EVs have several advantages over ICE vehicles, including lower operating costs, reduced emissions, and improved energy efficiency.

However, they also have some limitations, such as limited driving range and the need for charging infrastructure, and the EV batteries also have a limited lifespan and will need to be replaced after a certain amount of time or cycles.

The environmental impact caused by the manufacturing of Lithium-ion Batteries out weighs the benefits provided EVs.

The future of electric vehicles depends on how well the environmental impact created by electic batteries are addressed by the manufacturing companies.
