With the fusion of AI and robots, AI companion robots are moving beyond niche markets into practical applications in the home, education, healthcare, and entertainment. They are no longer mere toys, but complex intelligent agents that integrate AI processors, cameras, microphone arrays, servo motors, and power systems. Whether it’s emotional-support therapy robots for the elderly in senior care facilities, children’s educational robots used frequently in classrooms, smart pet robots (robotic dogs/cats) capable of complex biomimetic movements, or desktop AI interactive robots placed on desks for voice interaction, they all place unprecedentedly stringent demands on power systems. Grepow’s customized battery cell solutions, developed specifically for AI companion robots, perfectly balance high energy efficiency with long battery life, providing a robust power source for the robots’ continuous AI computing and physical movements.
The global companion robot market is experiencing explosive growth, with the market size projected to reach $3.81 billion by 2032. Companion robots are becoming more emotionally engaging, with richer movements and more compact designs. This trend exposes robots to extremely complex “multimodal power load” scenarios: after prolonged standby or low-power voice interactions, a robot may suddenly turn, stand up, jump, or perform complex gestures, causing multiple motors to activate simultaneously and triggering an instantaneous surge of extremely high peak current.
To ensure the safety and smooth interaction of AI companion robots across all scenarios, hardware engineers must overcome the limitations of traditional prismatic batteries when selecting batteries:
Exceptional instantaneous peak current tolerance: The battery must effortlessly handle high-load moments such as motor startup and posture recovery, ensuring voltage remains stable during high-current discharge and preventing system reboots.
Extremely low internal resistance and excellent thermal behavior: Low internal resistance not only reduces energy loss within the battery but also significantly suppresses heat generation during high-current discharge, extending the product's service life.
Efficient utilization of irregular spaces: The internal spaces of anthropomorphic or object-inspired robots (such as bionic pets) are highly constrained and irregular. Traditional off-the-shelf batteries create numerous dead zones, so custom-shaped or ultra-thin pouch batteries must be used to maximize every millimeter of space.
Stringent safety standards for children and the elderly: Since the product comes into frequent contact with the human body, including situations where children may drop or throw it, or the elderly may keep it close to their bodies for extended periods. the battery must feature extremely high thermal stability, short-circuit protection, and resistance to external impacts.
Communicative Smart BMS Power Management: The Battery Management System (BMS) must be capable of real-time communication with the robot’s main controller, providing precise estimates of State of Charge (SOC) and State of Health (SOH), and supporting intelligent low-battery strategies (such as alerting the user, reducing movement range, and automatically locating a charging station to recharge).

Round Battery for Desktop Robot
Suitable Applications: Spherical desktop interactive robots, robot heads/joint cavities, and emotional companion devices with circular bases or pebble-shaped designs.
Core Advantages: Traditional square batteries leave a significant amount of unusable "dead space" within circular, cylindrical, or curved cavities. Grepow's customized round pouch batteries perfectly conform to the internal contours of circular enclosures, improving space utilization by 20%–30%. Without altering the robot's lightweight, rounded design, they significantly increase battery watt-hour (Wh) capacity, enabling longer-lasting daily AI interactions.
