A giant step towards sustainability

The heart of this new technology is potassium ions that serve as charge carriers. Unlike lithium-ion batteries, which require critical minerals such as nickel or cobalt, Group1โ€™s KIB batteries use common materials, such as graphite for the anodes. This choice of materials not only simplifies the supply chain but also minimizes the environmental impact of battery production.

Compatibility and ease of integration

One of the key strengths of KIB technology is its compatibility with lithium-ion battery manufacturing processes. This feature enables a rapid and cost-effective transition for manufacturers looking to adopt more sustainable practices without the need for costly retrofits or major modifications.

Technological evolution: from prototype to production

Presented at the 14th annual Beyond Lithium conference, the battery has evolved from coin-cell to pouch-cell format, before reaching the 18650 format. At the heart of this innovation is Kristonite, a cathode material in the class of potassium Prussian whites, which promises better safety and cost performance than other technologies.

Promising energy density

With a nominal voltage of 3.7V and a targeted gravimetric energy density of 160-180 Wh/kg, KIBs are positioned to compete with lithium iron phosphate batteries (LFP-LIBs) in terms of capacity and performance, paving the way for demanding applications such as electric vehicles and portable devices.

Potential impact on the automotive industry

KIBs are distinguished by their exceptional longevity, capable of withstanding numerous charge cycles without significant loss of capacity. This feature is particularly attractive for the electric vehicle industry, where it could reduce the frequency of battery replacements and lower the total cost of ownership.

Towards wide adoption

With the start of sample distribution to Tier 1 cell manufacturers and OEMs, the stage is already set for broad adoption of this technology. The world could soon see these innovative batteries in action in a multitude of applications.

A promise of increased security

In addition to their economic and environmental performance, KIB batteries offer increased safety, a significant factor that could accelerate their market acceptance.
