Joyson Electronics: Embodied solid-liquid hybrid battery near mass production, using automotive supply chain capabilities to open overseas markets

As embodied intelligent robots move from demonstration scenarios to factories and homes, the energy bottleneck caused by short battery life and insufficient safety is becoming a major obstacle on the path to industrialization. Xu Wei, Chief Technology Officer (CTO) and Dean of the Research Institute of Ningbo Junneng New Energy Co., Ltd. (hereinafter referred to as "Junneng New Energy"), a subsidiary of Ningbo Joyson Electronic Corporation (hereinafter referred to as "Joyson Electronics"), said in an exclusive interview with a Securities Daily reporter that the team is working with multiple parties to advance the construction of embodied intelligence battery standards and shore up the shortcomings of robot energy systems. At present, the company's solid-liquid hybrid battery has reached mass production standards, and it is accelerating its overseas expansion by leveraging Joyson Electronics' global channels. Overcoming two major industry pain points and building a "smart" full-stack embodied energy solution Robot batteries are not simply scaled-down automotive batteries. In Xu Wei's view, battery products must not only be compact in structure and have higher power density, but also meet higher safety requirements after entering scenarios such as homes and elevators. Joyson Electronics is continuing to tackle the two major industry pain points of range and safety. In May 2026, Joyson Electronics and Beijing Enli Power jointly established Junneng New Energy, focusing on solid-state battery R&D and industrialization. Leveraging the complementary technical advantages of the two companies, the company quickly launched its first solid-liquid hybrid battery product. The product adopts a sulfide solid electrolyte route. By reducing the proportion of liquid electrolyte in the solid-liquid hybrid battery and optimizing the cell chemical system and pouch structure, it significantly improves safety and volumetric energy density. Its energy density ranges from 300 to 600Wh/kg, and it features high specific energy, high safety, and wide temperature range adaptability. Xu Wei, CTO and Dean of the Research Institute of Junneng New Energy, a subsidiary of Joyson Electronics Xu Wei said: "It is not just a change in the cell; only the combination of battery pack design, cell design, and BMS (battery management system) can create a truly excellent product." Based on Joyson Electronics' automotive-grade BMS technology, the battery's state-of-charge estimation accuracy can reach 1% to 3%, a 2 to 3 times improvement over traditional equipment, enabling precise prediction of energy consumption and avoidance of operational power failure risks; moreover, through sensors and algorithms, the battery pack can issue a thermal runaway warning 30 minutes to 2 hours in advance, significantly improving safety. The integrated full-stack solution of "cell/module/battery pack + BMS + data services + energy replenishment solutions" built by Junneng New Energy can fully adapt to various embodied intelligent devices such as humanoid robots, wheeled robots, robot dogs, and industrial AGVs (automated guided vehicles). The core logic of this solution is that robot batteries are no longer a single component but an intelligent energy system with perception capabilities. Its core competitiveness is reflected in high intelligence, high safety, and integration, with charging, discharging, application, and service jointly forming the robot energy industry system. Relying on its full-chain technical accumulation, Joyson Electronics can provide customized energy solutions for different scenarios: high-power-density power modules for heavy-load industrial robots, miniaturized long-endurance battery packs for service robots, and modular integrated battery systems for humanoid robots, meeting the differentiated needs of different scenarios. Promoting "standards to follow" for embodied energy and serving the global robot industry Beyond technology, industry standards related to robots are still under development. Xu Wei acknowledged: "The market is moving too fast, and the country does not yet have a clear understanding of safety standards for the embodied industry. As an important participant in the industry, we hope to work with everyone to formulate the standards. We have already established our own enterprise standards, and are currently actively working with leading customers, research institutions, and relevant departments to promote the formulation of group standards for embodied intelligent agent batteries, and gradually promote their upgrade to industry standards and national standards." In Xu Wei's view, the value of formulating and promoting standardized specifications goes beyond defining technical boundaries. On the one hand, standards will accelerate the implementation of the embodied intelligence industry; on the other hand, unified standards can dilute R&D and manufacturing costs and drive cost reduction across the industry. In the robot track, Joyson Electronics adopts a dual-wheel drive model of "in-house R&D + investment" to lay out core components. On the energy side, it relies on Junneng New Energy to deepen its work in solid-state batteries; on the execution side, through Ningbo Joyson Lingxi Intelligent Technology Co., Ltd. and its investment in Shanghai Critical Point Innovation Intelligent Technology Co., Ltd., it focuses on robot dexterous hands; in the robot "brain" segment, it established Ningbo Hyperplane Robot Technology Co., Ltd. to develop embodied intelligent agent controllers. At present, Joyson Electronics has built a complete product matrix covering robot brains, AI heads, dexterous hands, and energy solutions. It is cooperating with leading robot companies at home and abroad, and core components such as controllers have entered the mass production stage. If technology and standards are the hard power of Joyson Electronics in entering the track, its global layout is a soft barrier that is difficult to replicate. Xu Wei introduced: "Joyson Electronics has 25 R&D centers and 60 production bases around the world. Relying on the accumulation of its automotive components business, we are familiar with regulatory requirements in Europe, the United States, Japan, and other places, and this experience can fully empower the embodied intelligence business. We will advance both the domestic and international market lines in parallel." Joyson Electronics has long served leading global automakers and possesses a large-scale intelligent manufacturing system and rigorous automotive-grade quality control capabilities. It has the ability to deliver stably at low cost and in large volumes, and can also rely on massive deployment data to rapidly iterate products and shorten the commercialization cycle of technology. Extending from automotive electronics to embodied intelligence, Joyson Electronics' entry path is relatively steady: leveraging mature technologies to enter a new track, binding itself to the industrial ecosystem through standards development, and building long-term barriers through global capabilities. As solid-liquid hybrid batteries move from small-volume supply to large-scale mass production, this "technology-standards-global" development path will also be tested by the industrial market.
