Batteries of Lithium-Cobalt: fueling the EV revolution

Countries around the globe are working for a greener future and a crucial piece of the puzzle is electric vehicles (EVs).

In reality, the EV revolution is well underway, increasing in less than a decade from 17,000 electric cars in 2010 to 7.2 million in 2019, a 423x rise. At the same time, we sometimes take the range of materials that make modern technology work for granted. Going electric needs the use of minerals that are strategic, especially cobalt.

Today's Fuse Cobalt infographic comes to us and discusses how the cobalt in lithium batteries makes the differentiation for efficient and effective battery technology.

Cobalt: The Part of the Stable Battery

The high energy density of Cobalt enables batteries in smaller spaces to pack more energy , making them lightweight and efficient at the same time. Furthermore, its capacity to withstand high temperatures improves the protection and reliability of EVs.

In addition, cobalt increases battery durability and remains highly recyclable, enabling a more sustainable supply chain for batteries.

Despite its benefits, for different reasons associated with its supply chain, EV manufacturers are making efforts to reduce the cobalt content of their batteries:

Cobalt, which makes it difficult to acquire, is a by-product of nickel and copper mining.

At US$ 33,000 / tonne, more than twice the price of nickel, cobalt is costly.

In the Congo, the general population connects cobalt mining with child labor, harsh situations and corruption.

While cobalt may be synonymous with unethical mining activities, as shown by Tesla's agreement to purchase 6,000 tonnes of cobalt annually from mining giant Glencore, it still remains important for EV manufacturers.

How This Functions

Lithium ions flow from the cathode to the anode through the electrolyte when the battery is charged, where they are deposited for use. Electrons pass into an external circuit concurrently and are captured through a negative current collector in the anode.

The ions pass through the electrolyte from the anode to the cathode as the battery produces an electrical current (i.e. discharging), and the electrons change direction around the external circuit, powering up the EV.

Battery efficiency is primarily determined by the cathode composition. This is where the lithium-cobalt combination plays a key role for EV batteries.

Over the next decade, the EV market could experience colossal growth, but it faces several roadblocks. At present, the infrastructure for EV charging is costly and not as convenient as the local gas station, and lithium-cobalt batteries could help solve this barrier.
