Corning & Ensurge Partner to Power Next-Gen Microbatteries

OSLO, NORWAY – November 03, 2025 – Corning Incorporated and Ensurge Micropower ASA have announced a joint development and investment agreement poised to accelerate the advancement of solid-state microbattery technology. The partnership combines Corning’s deep expertise in materials science with Ensurge’s innovative battery architecture, targeting a wide range of applications from consumer electronics to medical implants. The move signals a growing confidence in the potential of solid-state batteries to address the limitations of current energy storage solutions.

A Synergistic Collaboration: Combining Expertise

Ensurge, headquartered in San Jose, California, and Oslo, Norway, specializes in developing advanced solid-state lithium microbatteries (SSLB). Their approach centers on a high-precision roll-to-roll (R2R) manufacturing process using stainless steel substrates, enabling the production of ultrathin batteries optimized for size-constrained devices. However, scaling production and achieving optimal performance required a partner with deep materials science capabilities. That’s where Corning comes in.

Corning, a global leader in specialty glass and ceramics, has been actively investing in materials for next-generation energy storage. Its Ribbon Ceramic Technology, a revolutionary R2R process for manufacturing high-quality ceramic ribbons, is particularly relevant to solid-state battery development. “The ability to produce thin, dense ceramic layers with precision is critical for enabling high-performance solid-state batteries,” explains one industry analyst. “Corning’s expertise in this area complements Ensurge’s battery design and manufacturing capabilities perfectly.”

The collaboration will focus on integrating Corning’s advanced materials – specifically, lithium garnet – into Ensurge’s battery architecture. Lithium garnet, known for its superior ionic conductivity and stability, offers a promising alternative to traditional liquid electrolytes. “This partnership isn’t just about combining technologies; it's about creating a fundamentally safer and more efficient energy storage solution,” a source close to the deal shared.

Financial Fuel for Growth & Scale

The agreement includes a financial investment from Corning, providing Ensurge with crucial resources to accelerate its development and scaling efforts. Corning will provide engineering resources valued at up to $5 million, convertible into Ensurge shares priced at NOK 1.11 per share. Additionally, Corning has an option to invest an additional $10 million through warrants exercisable at NOK 1.50 per share.

This investment arrives at a pivotal moment for Ensurge. While the company’s technology has shown considerable promise, scaling production to meet potential demand required significant capital. “Securing funding from a reputable and established company like Corning is a strong validation of Ensurge’s technology and business plan,” comments an investor familiar with the microbattery space. “It provides them with the financial runway needed to move from development to commercialization.”

However, the market has responded with some caution. Following the partnership announcement, Ensurge's stock experienced volatility, with recent technical analyses indicating a potential downward trend, despite long-term growth projections. This suggests that while the strategic partnership is viewed positively, investors remain watchful of the company’s execution and market dynamics.

Powering the Future: Applications and Market Potential

The partnership targets a diverse range of applications for its advanced microbatteries, including wearables, hearing aids, medical implants, and increasingly, Internet of Things (IoT) devices. “The demand for compact, high-performance power sources is growing exponentially,” says one technology consultant. “These batteries are particularly well-suited for applications where size, weight, and safety are critical.”

The microbattery market is poised for substantial growth. Forecasts predict the global market will reach upwards of $6.7 billion by 2035, driven by the increasing demand for smaller, more efficient electronic devices. The solid-state microbattery segment, in particular, is expected to experience rapid growth, with a projected CAGR exceeding 20% in the coming years.

The potential impact extends beyond consumer electronics. Medical implants, such as pacemakers and neurostimulators, could benefit significantly from the increased energy density and improved safety offered by solid-state batteries. Furthermore, the growing adoption of IoT devices in industrial and environmental monitoring applications will create a substantial demand for long-lasting, reliable power sources.

While the market is competitive, with established players like Murata, Cymbet, and Panasonic, the unique combination of Ensurge’s battery design and Corning’s materials science expertise positions them to capture a significant share of the growing microbattery market. The collaboration aims to deliver a truly disruptive technology that addresses the limitations of existing energy storage solutions and enables the next generation of portable and connected devices.
