TapTechNews August 4th news, according to InterestingEngineering, Group1 company announced the launch of the world's first potassium-ion battery with 18650 cylindrical housing. This breakthrough is expected to provide a sustainable and cost-effective alternative to traditional lithium-ion batteries.
Group1's chief executive officer, Alexander Girau, said: We are very pleased to launch the world's first 18650 potassium-ion battery.
Potassium-ion batteries are different from common lithium-ion batteries in that they use potassium ions as charge carriers. The new battery adopts the same size specification as the widely used 18650 lithium-ion battery, with a diameter of 18 millimeters and a length of 65 millimeters. This design enables potassium-ion batteries to be seamlessly integrated into existing devices and applications without the need for expensive redesign.
Alexander Girau said that this new battery has excellent performance after years of research and development. It has an outstanding cycle life and can maintain a relatively high capacity after multiple charge and discharge cycles, which is crucial for applications such as electric vehicles. In addition, the battery also has strong discharge performance and can effectively provide power when needed.
According to TapTechNews, the battery operates at a nominal voltage of 3.7V, thus ensuring compatibility with modern electronic devices and systems. In addition, the energy density of the battery can reach 160-180 Wh/kg, which is comparable to that of lithium iron phosphate batteries. Group1 said that potassium-ion batteries have excellent cycle life and outstanding discharge performance, making them an ideal choice for high-performance mobile applications such as electric vehicles and portable electronic devices.
It is worth noting that potassium-ion batteries use common commercial components, including graphite anodes, separators, and electrolyte formulations. This not only simplifies the supply chain but also reduces the dependence on key minerals such as nickel, cobalt, copper, and lithium.
Group1 company said that this potassium-ion battery using the exclusive Kristonite cathode material is a major breakthrough in battery technology. It can become a powerful alternative to lithium iron phosphate batteries and sodium-ion batteries.
