Tripartite cooperation on all-solid-state batteries Samsung to produce cells and install them in BMW vehicles Solid Power, a U.S. materials company, is participating Higher safety than lithium-ion
A game changer that will shake up the market
Samsung SDI of Korea, BMW of Germany, and Solid Power of the United States have joined forces to develop all-solid-state batt eries, known as ‘the dream batt ery,’ that is lighter, stronger and longer-lasting. Samsung SDI announced that it has signed a three-party business contract with BMW and Solid Power for the development and demonstration of all-solid-state batt eries.
Solid Power, a batt ery materials company, will supply solid electrolyte, the raw material. Samsung SDI will use this to produce all-solid-state batt ery cells with increased energy density and safety. BMW will then develop batt ery modules and packs based on these and demonstrate their performance. The goal is to install all- solid-state batt eries in BMW’s next-generation test vehicles to verify their actual performance. All-solid-state batt eries, unlike existing lithium-ion
batt eries, utilize solid materials instead of liquid electrolytes. This reduces the risk of fi re caused by electrolyte leakage and eliminates the need for individual cell sealing. They are highly stable and light so it is called ‘a game changer’ to reshape the dominance of the next- generation batt ery.
The only issue, however, is price. The cost of manufacturing all-solid-state batt eries is estimated to be three- to fi ve-times higher than liquid-based lithium-ion products. Moreover, the facility costs required to produce all-solid-state batt eries are estimated to be 10 to 20 times higher than those for lithium-ion batt eries. Consequently, no electric vehicles equipped with all-solid-state batt eries have yet been launched. However, the tripartite alliance between Samsung SDI, BMW, and Solid Power is seen as a strategy to overcome these technological and cost barriers.
Samsung SDI has maintained a close relationship with BMW since it was selected as a supplier of EV batt eries for BMW in 2009, and this agreement further enhances their technological cooperation.
Joo-young Go, head of the ASB Commercialization Team at Samsung SDI, explained, “Competitive batt ery technology directly leads to innovation in electric vehicles. We will continue to closely collaborate with global partners to lead the commercialization of all-solid-state batt eries.”
Martin Schuster, Vice President of Batt ery Cells at BMW Group, remarked, “With Samsung SDI’s participation, we can further accelerate the development of next-generation batt ery cell technology. This global cooperation will once again demonstrate BMW’s ultimate goal of providing
cutt ing-edge batt ery technology.” Meanwhile, John Van Scoter, President and CEO of Solid Power, emphasized, “We will work with global automakers and leading batt ery companies to commercialize all-solid-state batt ery technology.”
The prospect of the all-solid-state batt ery industry is very positive. The global all-solid-state batt ery market is projected to grow nearly sevenfold over the next fi ve years, from $148 million this year to $963 million in 2030.
