US automaker GM has announced that it will be extending its longstanding partnership with South Korean battery maker LG Energy Solution to focus on the development of prismatic cell technology for future electric vehicle (EV) models. The collaboration aims to diversify GM’s supply chain by incorporating multiple chemistries and form factors. GM plans to utilize the prismatic cells developed through this partnership to power its upcoming EV models alongside the pouch battery cells produced at their Ultium Cells joint venture plants in Warren, Ohio and Spring Hill, Tennessee.
Prismatic cells are flat and rectangular in shape with a rigid enclosure, allowing for efficient use of space within battery modules and packs. By utilizing prismatic cells, EV weight and cost can be reduced while streamlining manufacturing processes through the reduction of modules and mechanical components. LG Energy Solution brings with it extensive experience in prismatic cell production and holds a significant patent portfolio in battery design and manufacturing technologies, particularly in the area of packaging.
Kurt Kelty, GM’s VP of Batteries, expressed the company’s commitment to optimizing its battery technology through collaboration with LG Energy Solution. The goal is to enhance EV performance, improve safety, and reduce costs by developing the right battery chemistries and form factors. Together, GM and LG Energy Solution have transformed Ultium Cells into one of the largest battery cell manufacturers in North America, supporting GM’s diverse EV portfolio. This partnership underscores GM’s dedication to innovation in the EV sector and its focus on delivering sustainable mobility solutions.
The development of prismatic cell technology represents a significant step towards achieving GM’s vision for the future of electric mobility. By incorporating prismatic cells into their EV models, GM aims to leverage the benefits of space-saving design, cost efficiency, and simplified manufacturing processes. The collaboration with LG Energy Solution enables GM to tap into the expertise and patented technologies of a leading player in the battery industry, ensuring that their EVs are powered by cutting-edge battery solutions.
Overall, GM’s decision to extend its partnership with LG Energy Solution to focus on prismatic cell technology highlights the company’s strategic approach to enhancing its EV offerings. By leveraging the expertise of LG Energy Solution and incorporating prismatic cells into their battery technology portfolio, GM is poised to further strengthen its position in the rapidly evolving EV market. Through innovation and collaboration, GM is driving towards a future where electric mobility is not only sustainable but also efficient, safe, and cost-effective.
