The new rechargeable potassium-ion batteries use potassium ions as the charge carrier, unlike lithium-ion batteries, which use lithium ions. The batteries are the same size as the popular 18650 Li-ion batteries, measuring 18mm in diameter and 65mm long.

Group1 highlighted that this state-of-the-art potassium-ion battery is the result of extensive research and development. Remarkably, the battery’s performance exceeded expectations during a series of rigorous tests.

Test results successful

The battery demonstrated exceptional endurance while maintaining capacity over multiple charge and discharge cycles, a critical feature for mainstream consumer electronics and electric vehicles.

In addition, the high energy capacity of the potassium-ion battery makes it a suitable option for demanding consumers.

Operating at a constant voltage of 3.7V, the potassium-ion battery is compatible with modern electronic devices. It also achieved a gravimetric energy density of 160-180 Wh/kg, which is comparable to lithium-iron-phosphate batteries.

This high energy density means the battery can store a significant amount of energy relative to its mass, making it suitable for high-performance applications such as electric vehicles and portable electronics.

Group1 is confident that this potassium-ion battery will be a reliable alternative to lithium-ion and sodium-ion batteries and promises a new era in energy storage solutions.
