As the growth of the robot market accelerates, the battery—the core component driving these machines—is becoming increasingly important.

Batteries play as a key role in dictating a robot’s performance, runtime, and overall scope of use. To allow robots to operate longer and perform more various work, battery technology tailored to specific operating environment and purposes is essential.

As robots evolve, battery performance matters more

As robot types and their applications broaden, the demands placed on batteries are evolving as well. Because logistics and service robots must perform repetitive tasks like transporting goods over long periods, extended operational life and stable output are crucial.

Physical AI platforms like humanoids require even higher level of battery performance. Because they must run real-time AI computations while executing human-like movements, they need to deliver instant bursts of high power while maintaining sufficient overall capacity.

Adding to this challenge, robots have limited interior footprints and complex structures, which restricts the space available for battery installation. This necessitates high energy density batteries that can store significant power even in tight spaces. Developing battery technology that maximizes space efficiency while delivering long runtime and high power output is considered a central objective. 

SAMSUNG SDI’s battery technologies encompass entire robotics industry

Aligned with this market trend, SAMSUNG SDI is building its competitiveness in robotics around cylindrical and all-solid-state batteries.

Armed with high power output and a broad spec portfolio, SAMSUNG SDI’s cylindrical batteries serve as key products meeting market demand. The flexible form factor of cylindrical batteries allows them to adapt to robot platforms, making them highly versatile logistics and service roles.
