With the continuous advancement of humanoid robot technology and its wide application in multiple industries, the demand for dedicated batteries is rising sharply. Given that humanoid robots need to perform diverse and complex tasks and maintain a long-term operational state, their power demand has also increased significantly. This has prompted us to seek battery solutions that are lighter, have higher energy density, and can maintain safety and efficiency during continuous operation to meet the growing demand.

What challenges do robot batteries face?

The development of batteries for humanoid robots faces several key challenges. The primary issue is how to strike a balance between energy density and safety. As robots require batteries to be compact in structure, light in weight, and capable of storing sufficient energy to support complex movements and the long-term operation of sensors, it is necessary to increase energy density. However, this improvement is often accompanied by an increase in safety risks, such as the possibility of overheating or even fire. Another challenge is to achieve the fast charging function while ensuring that the battery has a long cycle life, which is crucial for improving the operational efficiency of the robot. In addition, the battery also needs to have the ability to work stably under various temperatures and different environmental conditions, which undoubtedly increases the complexity of the design. When integrating these batteries into the robot structure, it is also necessary to consider how not to affect the robot's flexibility and overall weight distribution, which further increases the difficulty of the development work. Therefore, the design of humanoid robot batteries is a complex process that takes into account multiple factors and seeks the best solution.

Battery solutions for humanoid robots

The semi-solid NMC battery launched by Yuanli New Energy has an energy density of 350Wh/kg, effectively balancing the high energy demands with the requirements of lightweight design. This is particularly important for humanoid robots, as they need to meet the large power consumption without adding additional loads. Greep has launched a fast-charging battery with a capacity of up to 7C, which can quickly replenish power and significantly reduce operation interruption time. In addition, the high-discharge rate batteries we provide have a discharge capacity of up to 50C, ensuring the stability and efficiency of humanoid robots when performing high-energy-consuming tasks. These features make Grep's lithium-ion batteries an ideal choice for humanoid robot applications in many industries, capable of withstanding various harsh operating conditions. Furthermore, the application under different temperature and environmental conditions further increases the challenge of battery integration design. Integrating batteries ingeniously into the robot structure without sacrificing the robot's flexibility and reasonable weight distribution undoubtedly poses higher requirements for the development work.

Yuanli NMC semi-solid battery adopts the laminated pouch cell process. The cathode composition of NMC(Ni-Mn-Co) contains 80% nickel, 10% manganese and 10% cobalt. This formula technology will significantly break the energy density of existing lithium batteries, with the maximum energy density reaching 350Wh/kg. After 1000 cycles, the capacity retention rate can be maintained at over 80%, and the dynamic voltage imbalance is less than 100mV. This technology is more reliable and lighter, and is suitable for various robots and professional fields such as mapping, E-VTOL, and consumer electronics. The range of drones is longer. NMC semi-solid batteries can also be customized to perfectly fit the shape or capacity of the device you need. As a battery manufacturer, we also offer OEM and ODM services.
