Michigan-based energy storage company Our Next Energy (ONE) has signed an agreement with BMW Group to incorporate ONE’s Gemini Dual-Chemistry battery technology into the BMW iX all-electric Sports Activity Vehicle.

The aim is to demonstrate the iX can achieve a 1000km range on a single charge and the prototype vehicle is expected to be ready by the end of the year.

Dual-chemistry refers to the battery containing cells optimised for power delivery and cells optimised for energy storage. The power delivery element, engineered from the “safest and most durable materials” are designed to meet the demands of daily driving. The energy storage element integrates anode-free cells, storing more energy in less space, while minimising the use of nickel, cobalt and eliminating graphite.

ONE says the technology reduces lithium use by 20%, graphite by 60% and minimises the use of nickel and cobalt. In doing so “it is creating more sustainable energy storage technology that can significantly reduce environmental impact.”

“We are thrilled to be working with BMW to demonstrate our Gemini long-range battery technology to consumers,” said Mujeeb Ijaz, founder and CEO of ONE. “As EV adoption grows, drivers are learning that real-world conditions can significantly reduce the performance of their batteries. Common situations like maintaining highway speeds, winter temperatures, climbing mountains, towing, or a combination of all four things present challenges to electric vehicles. We plan to pack twice as much energy into batteries, so EVs can easily handle long-distance driving in real-world conditions.”

“We are well-positioned to incorporate ONE’s IP into BMW’s SAV line,” said Jürgen Hildinger, BMW Group New Technologies Head of High Voltage Storage, “We are confident that given economic viability, this can lead to commercial opportunities and strategies to integrate ONE’s battery technologies into our future battery electric vehicle product line-up.”

BMW i Ventures is an investor in ONE and recently led a $65M funding round. Baris Guzel, partner at BMW i Ventures said “Our Next Energy is working to fundamentally reinvent the battery while focusing on sustainability, safety, and cost; three key factors which will help speed the development and adoption of battery electric vehicles.”
