On December 18th, Contemporary Amperex Technology Co., Limited (CATL), a global power battery giant, announced the official commissioning of the world’s first large-scale new energy power battery PACK production line for humanoid intelligent robots at its Zhongzhou Base. This humanoid robot can precisely complete sophisticated operations including the plugging of battery connectors, boasting a steady success rate of more than 99% for such tasks. It has achieved the same operational tempo as seasoned workers, and its daily work output has tripled. 2025 marks the inaugural year of mass production for humanoid robots. Industry leaders have completed thousand-unit deliveries, and the robots have entered factories for small-scale trials.
Humanoid robots are growing from “awkward and fledgling demonstrators” to “capable workers that perform concrete tasks”. They have evolved from pursuing simple movements and motions to creating economic value in specific scenarios — undertaking simple and repetitive work in high-end manufacturing sectors such as automotive electronics. It is projected that by 2035, the total demand for humanoid robots in three major segments of China’s industrial landscape — automotive manufacturing, electronic manufacturing and logistics & warehousing — will reach 484,000 units.
Large AI models serve as the brain of humanoid robots, while battery systems act as their heart, delivering energy to power the robots’ operation. Robot batteries must meet the following requirements:
1．High energy density & high power density: Energy density determines the endurance of robots, while power density dictates their instantaneous power output.
2．Superior safety: Humanoid robots operate in complex working environments, which impose higher requirements on the safety performance of their batteries.
3．Ultra-long cycle life & fast charging capability: Commercial robots are required to work for extended periods, which imposes stringent requirements on the cycle life and fast charging performance of batteries.
Currently, lithium batteries are the primary power source for humanoid robots. The efficient and precise electrolyte filling is a critical process that determines battery performance, and Guangzhou Ascend provides high-precision electrolyte filling pumps to guarantee the quality of battery production.
Guangzhou Ascend’s high-precision electrolyte injection pumps serve well-known battery enterprises both at home and abroad, meeting customers’ diverse injection requirements and application scenarios. The injection volume ranges from the microliter (μL) to liter (L) scale with ultra-high injection precision, achieving a laboratory-level accuracy of up to 0.1%. We provide matched needle valves for both vacuum and atmospheric pressure injection, delivering comprehensive electrolyte injection solutions for batteries across multiple scenarios.
