SK On, a global electric vehicle battery manufacturer, is set to enhance its collaboration with Solid Power, a leading U.S.-based developer of solid-state battery technology, aiming to expedite the advancement of all-solid-state batteries (ASSBs).
The announcement was made by SK On, revealing that it has recently entered into a research and development technology license agreement with Solid Power during CES 2024, the world's largest IT expo held last week.
As per the agreement terms, SK On gains the right to utilize Solid Power's technologies related to ASSB cell design and pilot production processes for research and development purposes. Solid Power will play a crucial role in assisting the South Korean battery manufacturer in accelerating the development of ASSBs known for their safety and high performance. Additionally, the Colorado-based company will supply sulfide-solid electrolyte to SK On.
The strengthened partnership will see SK On taking steps to establish an ASSB pilot line at its Battery Research Institute in Daejeon, Korea, by the year 2025. A pilot line is a production line designed to test and validate new products or technologies before mass production.
The signing ceremony, which took place at the Las Vegas Convention Center in Nevada on January 10, was attended by SK On Chief Commercial Officer Sung Min-suk and Solid Power Chief Executive Officer John Van Scoter.
SK On's objective is to enhance the cycle life and energy density of ASSBs through the integration of its cell design and production expertise with Solid Power's technologies in sulfide-based electrolytes and cell solutions. Following the successful collaboration, both companies plan to continue their partnership in commercializing ASSBs.
In 2021, SK On had committed to investing USD 30 million in Solid Power for the joint development of next-generation ASSBs. The ongoing discussions between the two companies have been aimed at formulating detailed cooperation plans.
An ASSB battery employs solid electrolytes instead of liquid or gel-based electrolytes, reducing the risk of fire. Furthermore, the use of solid electrolytes allows for a reduction in the weight and volume of batteries, surpassing the current capacity limits of lithium-ion batteries.
Solid Power, established in 2011, is recognized for developing industry-leading technologies in sulfide-based ASSBs. The company is particularly known for its expertise in large capacity cell technologies and solid electrolyte production processes.
SK On has been actively strengthening collaborations with partners to develop technologies for ASSBs, supplementing its own research and development programs.
