Samsung SDI has signed a memorandum of understanding with South Korean carmaker KG Mobility to co-develop advanced battery pack technologies for electric vehicles.
Under the agreement, the two companies will work together on battery pack systems built around Samsung SDI’s 46‑series cylindrical cells and extend cooperation on technologies aimed at future iterations of battery packs.

The newly developed packs are intended for use in KG Mobility’s next wave of electric models.
The partners also intend to deepen their strategic relationship by sharing perspectives on medium- to long-term trends in the global battery market and by pursuing joint research and development projects.
Samsung SDI described the 46‑series cylindrical cell as a high energy density product designed to support longer driving ranges and rapid charging.
The South Korean battery manufacturer said the cell is engineered for stability and longevity to maintain performance across a wide range of operating conditions.
According to Samsung SDI, the cell uses high-capacity high-nickel NCA cathode materials alongside its proprietary Silicon Carbon Nanocomposite anodes, a combination it says helps mitigate swelling and extend service life.
The design also features a tabless structure intended to cut internal resistance and improve current flow, which the company says supports higher power output and quicker charging.
The manufacturer added that strengthened thermal management and updated production processes are aimed at bolstering safety and reliability.
A Samsung SDI official said: “This partnership once again proved the differentiated technological competitiveness of our 46-series cylindrical batteries in both Korean and global EV markets. We will continue to strengthen our technology leadership in the next-generation global battery industry.”
Separately, reports last month in The Korea Economic Daily said Samsung SDI is in discussions to supply energy storage system batteries to Tesla, with the potential contract estimated at around Won3tn ($2.11bn) or more.
