Samsung SDI Aims for Mass Production of Solid State Batteries for Robotics

Samsung SDI is pursuing leadership in solid-state battery technology, aiming to shape both the robotics market and broader energy-storage standards. At InterBattery 2026, held at the Coex Convention Center in Seoul, visitors viewed the company’s solid-state battery offerings at its booth.

Samsung SDI executive Hyun, a senior manager in the Strategy Marketing Office, spoke on the event’s side program, The Battery Conference (TBC). He said the company expects to complete mass-production readiness for its solid-state batteries in the second half of next year and intends to help set battery-technology standards in the global robotics market.

Hyun highlighted Samsung SDI’s patent strategy, noting that the company has proactively filed for next-generation core-material technologies and that its portfolio includes more than 700 patents in cylindrical-battery components alone. He framed this as a foundation for the firm’s competitive edge in future energy-storage solutions.

In addition to solid-state cells, Samsung SDI supplies cylindrical battery solutions that incorporate other advanced technologies. These include high-nickel NCA (nickel-cobalt-aluminum) cathodes, silicon-graphite composite anodes, and tabless designs designed for high output, all of which are distributed to global robotics manufacturers.

The executive described solid-state batteries as offering safety, lighter weight, and higher energy density, capable of extending robot operation times to about eight hours. He cited four core elements for robotics batteries: high energy density with fast charging, high-output capability, safety, and design flexibility, and said the company is advancing cylindrical-cell development, flexible pack design, and heat-diffusion barrier technologies to achieve these goals.

This year, Samsung SDI introduced the branding for its solid-state line as “SolidStack” at InterBattery, signaling a marketing push around the technology in addition to its technical development.

Hyun also projected sizable growth for the global robotics market. He said the number of robots in use worldwide is expected to rise from roughly 500,000 last year to about 2.04 million by 2030, with humanoid robots accounting for about half of that total, around one million units.

He attributed much of the growth to rapid advances in AI, arguing that the era of fully autonomous robots is taking hold. He stated that Samsung SDI is prepared with robot-optimized, high-performance battery solutions to drive penetration in the global market.

Context for U.S. readers: InterBattery is a major international expo focused on batteries and related technologies, underscoring Korea’s role as a leading supplier of cells and chemistries for consumer electronics, industry, and emerging robotics applications. Solid-state batteries are viewed as a potential breakthrough for energy density, safety, and charging speed. Developments from Samsung SDI—especially a formal branding like SolidStack and a strong patent portfolio—could influence partnerships, licensing, and competition in the U.S. market, where robotics, automation, and defense sectors depend on secure, high-performance power sources and diversified global supply chains.
