With the rapid development of science and technology, robotic battery technology continues to iterate, and the market demand also changes. In this context, it is particularly important to deeply analyze the core materials, technical parameters, industry chain levels, and the impact of technological advances on the market pattern of batteries.
1.. Core Material and Process Differences
1.1Battery type and energy density
Robot batteries are mainly divided into three types: lithium batteries (including lithium polymer batteries), nickel-metal hydride batteries and lead-acid batteries. Among them, polymer lithium-ion batteries have become the first choice for high-end robots due to their high energy density (up to 500Wh/kg) and lightweight. However, their cost is three to five times higher compared to ordinary 18650 lithium batteries. For example, with the use of polymer lithium batteries in drones, the selling price of a single 5300mAh battery can reach 600 yuan, while the price of a rechargeable treasure with the same capacity is only about 100 yuan.
1.2Material and Safety Protection Costs
High-end batteries usually need to be equipped with intelligent management systems, such as overcurrent protection and temperature monitoring, and use flame retardant housing materials (e.g., PVC with epoxy resin). In the case of industrial robot batteries, for example, additional safety modules may increase the cost by 20% to 30%. In addition, the development of bionic “living skin” battery technology in Japan is further driving up material costs.
With a better understanding of the different battery types and their materials, it is possible to better select the right battery solution for a particular application, thus improving the overall performance and safety of the robotic system.
2.Technical parameters and application scenario diffe
2.1Parameter dimension
| Parameters | Entry-level (USD 1K range) | Premium (USD 10K range) |
| Capacity | 60Ah (Runtime: 1-2 hours) | 15Ah (Supports 5-hour high-power output) |
| Continuous discharge current | ≤60A | ≥100A (Instantaneous multiple peak power support) |
| Cycle life | 500 cycles | 2000 cycles (With deep charge/discharge protection algorithms) |
2.2 Typical Scenario Differences
Household service robots, such as sweeping robots, usually focus on light weight and use 2.25kWh batteries. These robots mainly work in indoor environments, with relatively low requirements for range and power, and focus more on lightweight and flexibility to easily maneuver between furniture. Industrial robots, on the other hand, need to withstand extreme temperatures of – 10 ℃ ~ 50 ℃, the shell protection level of IP67. the complexity of the industrial environment, may be faced with high temperature, low temperature, humidity, dust and other harsh conditions, which requires batteries to have a higher stability and reliability, able to work properly in a variety of extreme environments. Therefore, the industrial-grade robot battery in the choice of materials, structural design and manufacturing process are very different from the home service class robot battery, which also leads to the price difference.
3. Industry chain hierarchy and brand premiums
3.1 Supply chain complexity
Humanoid robot battery involves 30+ core components such as harmonic reducer (single machine value 26,000), sensor module, etc., and the head manufacturers such as Xinwanda have set up a dedicated production line, with R&D investment accounting for more than 8%. Complex supply chain means higher management cost and technical integration difficulty. Each core component needs to undergo strict screening and testing to ensure its compatibility and stability with the battery. Head manufacturers can better control the production process and product quality by setting up dedicated production lines, but this also requires a lot of capital investment and technological research and development. In addition, the increase in R&D investment will be apportioned to the product cost, thus increasing the price of the battery.
3.2 Customized development cost
Special scenarios (e.g. medical explosion-proof, polar research) require customized electrolyte formulations, with a development cycle of 6 – 12 months. In the field of customization, EOF has also made some achievements. An AI escort robot battery has increased its unit price by 40% due to the addition of a low-temperature self-heating function, and EOF’s technical support may be behind this. Customized development requires special design and R&D for specific application scenarios and needs, which not only requires a lot of manpower, material resources and time, but also professional technical knowledge and experience. Customized electrolyte formulations, special functional designs, etc. will increase the development and production costs of the battery, and when EOF meets these customized needs, these costs are also reflected in the product price, which leads to an increase in the price of its customized battery products.
4. Technology Iteration and Market Landscape
4.0 Solid-state battery commercialization process
Semi-solid batteries have been applied to floor sweeping robots, with energy density exceeding 500Wh/kg. Guangzhou Lushan New Material and other enterprises are promoting the research and development of all-solid-state batteries, and the cost is expected to be reduced to 70% of the existing lithium batteries in 2030. In this technological change, EOF also actively layout solid-state battery field. As a new type of battery technology, solid-state batteries have higher energy density, better safety and longer service life. With the continuous progress of technology, semi-solid batteries have started to be applied in some fields, while the research and development of full-solid batteries are also being actively promoted. Once all-solid-state batteries are commercially mass-produced, their cost reduction will have a profound impact on the robotics battery market and may change the existing market pattern, while EOF is expected to occupy a favorable position in the future market by virtue of its investment in the R&D of solid-state batteries.
4.2 Layout of Head Enterprises
Tesla Optimus adopts 21700 cylindrical battery packs, with a target cost of <$20,000 for mass production. As a globally recognized technology enterprise, Tesla has profound technical accumulation and strong R&D strength in battery technology and robotics. EOF is also exploring and innovating in the field of robot battery, although the current battery technology route is different from that of Tesla, EOF has been improving the performance of its products by optimizing the battery design and production process, and the battery capacity of FigureAI has been increased by 50% to 2.25kWh, which can support 5 hours of continuous operation. The layout and technological innovation of the leading companies will lead the development direction of the robot battery market and promote the technological progress and cost reduction of the industry, and EOF will also continue to improve its own technical level and market competitiveness through competition and cooperation with other leading companies in this process.
