Lithium-Cobalt batteries: fueling the EV revolution

Countries around the globe are aiming towards a greener future and electric vehicles ( EVs) are a vital piece of the puzzle.

In fact, the EV revolution is well underway, rising from 17,000 electric cars in 2010 to 7.2 million in 2019 in less than a decade, a 423x increase. At the same time, often we take for granted the variety of materials that make modern technology work. Going electric calls for the use of strategic minerals , especially cobalt.

Today's infographic on Fuse Cobalt comes to us and explains how the cobalt in lithium batteries differentiates between effective and productive battery technology.

Cobalt: The Stable Battery Component

Cobalt's high energy density allows batteries to pack more energy in smaller spaces, making them lightweight and at the same time efficient. In addition, its ability to withstand high temperatures enhances EV safety and durability.

In addition, cobalt improves the longevity of batteries and remains highly recyclable, allowing a more sustainable battery supply chain.

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

Cobalt, which makes acquisition difficult, is a by-product of the mining of nickel and copper.Cobalt is expensive at US$ 33,000 / tonne, more than twice the nickel price.The general population of the Congo ties cobalt mining to child labor, harsh conditions and corruption.

Although cobalt may be synonymous with unethical mining practices, it remains relevant for EV manufacturers, as shown by Tesla's agreement to buy 6,000 tons of cobalt annually from mining giant Glencore.

How This Functions

When the battery is charged, lithium ions flow from the cathode to the anode via the electrolyte, where they are stored for use. Electrons pass simultaneously through an external circuit and are collected in the anode via a negative current collector.

As the battery generates an electrical current (i.e. discharging), the ions migrate through the electrolyte from the anode to the cathode, and the electrons change direction along the external circuit, powering up the EV.

Battery efficiency is determined mainly by the composition of the cathode. For EV batteries, this is where the combination of lithium-cobalt plays a key role.

The EV market might experience colossal growth over the next decade, but it faces many roadblocks. The EV charging infrastructure is currently expensive and not as convenient as the local gas station, and lithium-cobalt batteries could help overcome this obstacle.
