This substantial investment underscores their dedication to advancing the adoption of EVs and securing a sustainable transportation future.

Accelerating the EV Market’s Growth and Transformation

The Samsung SDI-GM partnership holds immense potential for the EV industry. By harnessing the power of cylindrical battery cells, GM can significantly enhance the efficiency and range of their electric vehicles, attracting a wider consumer base.

Furthermore, the joint manufacturing facility’s substantial production capacity will help meet the escalating demand for EVs, driving their widespread adoption and expediting the transition to sustainable transportation.

A Catalyst for Collaboration & Innovation

While the primary focus of this partnership is on GM’s EV models, the utilization of Samsung’s cylindrical cells has the potential to extend to other companies as well.

This fosters a collaborative environment within the EV industry, encouraging the development of groundbreaking technologies and further propelling the industry’s evolution.

Unlocking The Advantages Of Cylindrical Battery Cells

Cylindrical batteries have emerged as a preferred choice for electric vehicles due to their numerous advantages. Here are some key benefits of using cylindrical batteries in EVs.

Higher Energy Density

Cylindrical batteries offer higher energy density compared to other battery types. This means they can store more energy in the same physical size, allowing EVs to achieve longer driving ranges and improved performance without taking up more space.

Enhanced Safety

Cylindrical batteries are known for their robust design and safety features. The cylindrical shape allows for better heat dissipation, reducing the risk of overheating and potential thermal runaway incidents. This ensures a safer driving experience for EV owners.

Better Thermal Management

The cylindrical shape of these batteries allows for effective thermal management. Heat dissipation is more efficient, which helps maintain optimal battery temperature during charging and discharging. This, in turn, extends the battery lifespan and ensures consistent performance.

Scalability & Adaptability

Cylindrical batteries are highly scalable and adaptable to different EV models. They can be easily customized to fit various vehicle sizes and configurations, providing flexibility to automakers in their design and manufacturing processes.

Companies Using Cylindrical Batteries In EVs

Several prominent automakers and technology companies have already embraced cylindrical batteries for their electric vehicles. 


Tesla, one of the leading EV manufacturers, has been utilizing cylindrical battery cells in their vehicles since their inception. Their popular models, such as the Model S, Model 3, and Model X, all use cylindrical batteries manufactured by Tesla in partnership with Panasonic.


NIO, a Chinese electric vehicle company, uses cylindrical battery cells in their models, including the ES8, ES6, and EC6. The batteries for NIO are manufactured by CATL (Contemporary Amperex Technology Co. Limited), a leading battery manufacturer in China.


Rivian, an American electric vehicle startup, also relies on cylindrical battery cells for their all-electric models. Rivian’s highly anticipated R1T electric pickup truck and R1S electric SUV both utilize cylindrical batteries to deliver impressive performance and range.

As the demand for EVs continues to grow and technology advances, more companies are likely to adopt cylindrical batteries to take advantage of their benefits and contribute to the development of greener and more sustainable transportation.


The strategic partnership between Samsung SDI and General Motors marks a significant milestone in the EV industry. By harnessing the numerous advantages of cylindrical battery cells and establishing a joint manufacturing facility with remarkable production capacity, this collaboration has the power to revolutionize the EV industry.
