Solid-State Batteries: The Next Power Source for Robotics—Joyson and Enpower Announce Joint Development

Major automotive parts supplier Joyson Electronics and next-generation battery manufacturer Enpower have entered into a strategic partnership. The two companies will focus on developing a next-generation energy system for AI robotics that integrates battery cells, Battery Management Systems (BMS), and data services.

1. Background of the Partnership and Roles of Each Company

As robots become more sophisticated, there is an urgent need to simultaneously achieve high energy density, safety, and lightweight design—areas where conventional batteries have fallen short.

Joyson Electronics
- Role: Providing automotive-grade BMS technology and data services.
- Track Record: As a world-class supplier providing BMS products to manufacturers like Volkswagen, BMW, and Mercedes-Benz, the company is repurposing energy management expertise cultivated in the automotive sector for robotics.
Enpower
- Role: Research, development, and industrialization of all-solid-state batteries.
- Track Record: Possesses semi-solid and quasi-solid state battery technology with an energy density of up to 600 Wh/kg, which is already being utilized in robots and drones.

2. Innovations Brought to the Robotics Industry by Solid-State Batteries

Compared to conventional lithium-ion batteries that use liquid electrolytes, solid-state batteries offer several advantages for robotic applications:

Miniaturization and Weight Reduction: Higher energy density allows for a significant reduction in weight and size while maintaining the same battery capacity, thereby improving a robot’s operational efficiency.
Enhanced Safety: Because solid electrolytes have an extremely low risk of ignition, they are essential for collaborative robots and home AI robots that coexist with humans.
Support for High-Speed Computing: Solid-state batteries can provide stable and efficient power to handle the massive energy consumption required by the advanced processing capabilities of AI robots.

Market Context and Technological Outlook

Rapid Expansion of the AI Robot Market (Rise of Humanoids)

Development competition is intensifying for humanoid robots, such as Tesla’s Optimus and those from Figure. Because these robots perform complex joint movements and AI processing, they face challenges where traditional batteries are either too heavy or have insufficient runtime. The transition to solid-state batteries is the key to overcoming this bottleneck.

The “Robotics Pivot” in Automotive Technology

There is an accelerating trend where automotive control technologies (like BMS and autonomous driving algorithms) are being expanded into the robotics sector.

Automotive-Grade Reliability: Adopting BMS that meets automotive standards—designed to withstand harsh environments—is expected to lower failure rates and extend the lifespan of industrial robots.

Commercialization Roadmap for Solid-State Batteries

While full-scale adoption of all-solid-state batteries in electric vehicles (EVs) is projected for the late 2020s (around 2027 to 2030), niche, high-value fields like robotics and drones are attracting attention as “early adopter markets” where these batteries will see usage ahead of the automotive sector.

Conclusion: The Significance of the Partnership

This partnership goes beyond a simple supplier-client relationship; it aims to “intellectualize energy management.” By combining Joyson’s global customer network with Enpower’s cutting-edge battery technology, the social implementation of AI robotics is expected to accelerate significantly.
