In 2025, as the embodied intelligence robot industry evolves from laboratory research and development to the stage of large – scale mass production, the demand for robot batteries is experiencing explosive growth. According to GGII’s forecast, the shipment volume of lithium – ion batteries for global embodied intelligence robots will reach 2.2 GWh in 2025, and the demand will exceed 100 GWh by 2030, with a compound annual growth rate of over 100% from 2025 to 2030. Facing such a huge and rapidly growing market, it is crucial to choose a reliable supplier when purchasing 24v robot batteries. The following are 7 core questions for you to pose to suppliers in detail.
I. What are the battery performance indicators?
(1) Energy density
For robots, especially service – type and humanoid robots, it is necessary to store as much electricity as possible in a limited space to extend the robot battery life. For example, although the suppliers of Unitree Go2/A1 series quadruped robots are not directly disclosed, the nominal battery capacity of the products is 1000 – 2000 Wh, with a voltage of 48 V, and it can support 1 – hour continuous movement. This requires the battery to have a high energy density. Ask the supplier how much the energy density of their battery can reach. For example, the energy density of solid – state batteries exceeds 400 Wh/kg, which has a great advantage compared with traditional robot tondeuse batterie lithium.
(2) Rate performance
For robots that need to start, brake, or move quickly frequently, high – rate discharge performance is particularly crucial. Such as AGV trolleys in industrial scenarios and some quadruped robots that need to make agile movements. Whether the battery provided by the supplier supports high – rate discharge, for example, whether it can reach a continuous discharge capacity of 5C or even higher, determines the power performance of the robot under complex working conditions.
(3) Cycle life
Robot batteries will undergo frequent charge – discharge processes, and the cycle life directly affects the use cost and replacement frequency of the battery. Generally speaking, in scenarios with frequent charge – discharge, it is ideal for the battery to ensure a cycle life of more than 2000 times. You can ask the supplier to provide the test data and standards for the battery cycle life to evaluate the long – term reliability.
II. Can customized services be provided?
Different types of robots have different requirements for the size, shape, interface protocol, etc. of the battery. For example, the battery of a sweeping robot needs to be adapted to its compact internal space, while special – operation robots may require special protection designs. Whether the supplier has the ability to customize battery modules and can develop an adapted robot battery management system according to the unique needs of the robot, including a customized BMS (Battery Management System) to achieve intelligent temperature control and power monitoring, is very important in the procurement process.
III. How is the battery safety guaranteed?
Safety is the top consideration for battery use. Especially in some scenarios with extremely high safety requirements, such as the applications of fire – fighting and explosive – disposal special robots. Inquire with the supplier about the safety protection measures taken for their batteries, such as whether there are over – charge, over – discharge protection, and short – circuit protection mechanisms. Take lithium iron phosphate (LFP) batteries as an example. They perform outstandingly in terms of safety and are more suitable for robots in fixed scenarios. Whether the batteries provided by the supplier have similar advantages or better solutions in terms of safety performance.
IV. What is the production and supply capacity?
With the rapid expansion of the robot market, the demand for batteries will also increase sharply. The supplier needs to have a strong production and supply capacity to meet the order requirements of the purchasing party. Ask the supplier about their production capacity plan, for example, what is the estimated production capacity in 2025 and whether there is an emergency plan to deal with peak orders. At the same time, understand the advancement and automation level of their production equipment, which will affect the production efficiency and quality stability of the products. For example, Xindao Intelligent is the only equipment enterprise in the world that has achieved full coverage of the mass – production process for solid – state batteries, with a yield rate of key equipment reaching 95%, providing turnkey solutions for car companies and battery manufacturers. If the supplier has similar advanced equipment, it is undoubtedly an advantage.
V. Is the quality control system complete?
A complete quality control system is the key to ensuring the stable quality of batteries. Ask the supplier about their quality control process, from raw material procurement, production process to finished product inspection, whether they follow strict industry standards and specifications. For example, whether they have passed the ISO quality management system certification, and whether there are strict sampling and full – inspection mechanisms for various performance indicators of the battery. In addition, the yield rate is also an important reference index. For example, in 2024, the yield rate of solid – state batteries of some enterprises has increased from 32% in 2022 to 78%. A higher yield rate means a lower defective rate and more reliable product quality.
VI. What is the cost and price composition?
Cost is an important factor in the procurement decision – making. Require the supplier to explain in detail the cost composition of the battery, including raw material costs, production costs, R & D costs, etc. Take solid – state batteries as an example. In their cost items, electrolyte materials, lithium foil preparation, packaging equipment, etc. each account for a certain proportion. By understanding these, the rationality of the cost and the future price reduction space can be analyzed. At the same time, compare the prices of different suppliers and choose a product with high cost – performance on the premise of ensuring quality. However, it should be noted that price cannot be the only criterion. An overly low price may mean quality risks.
VII. How about after – sales service and technical support?
After – sales service and technical support are equally important after purchasing the battery. Ask the supplier whether they provide battery maintenance and repair services and what the response time is. When there is a problem with the battery, whether they can provide timely technical support to assist in troubleshooting. For example, whether there is a professional after – sales team that can provide remote guidance or on – site services. In addition, whether the supplier has a corresponding solution for battery recycling, which not only meets environmental protection requirements but may also involve certain cost savings.
In the process of robot battery procurement in 2025, posing these 7 core questions to suppliers helps to comprehensively understand the product and service capabilities of suppliers, thus making a more informed and reliable procurement decision and providing a solid power guarantee for the efficient operation of robots.
