Israeli battery technology company Addionics and South Korea’s PNT Materials have announced a strategic partnership to develop, manufacture and commercialize prismatic LFP battery cells designed for large-scale energy storage systems. The collaboration is aimed primarily at addressing the surging energy needs of AI-driven data centers, as power consumption rises sharply across high-performance computing infrastructure and demand grows for stable, reliable and cost-efficient energy supply.

Prismatic LFP cells, based on lithium iron phosphate chemistry, are housed in rigid rectangular casings optimized for dense, controlled deployment in large energy storage systems. Unlike smaller cells used in consumer devices, these batteries are designed for long operational lifetimes, thousands of charge and discharge cycles, and a particularly high level of safety. For data centers, where batteries play a critical role in grid stability and as a backbone for uninterrupted AI workloads, the combination of safety, durability and effective thermal management makes prismatic LFP chemistry an increasingly preferred choice.

The partnership is intended to combine Addionics’ structural battery technology with PNT’s industrial manufacturing capabilities, with the goal of developing a new generation of energy storage batteries tailored for continuous data center operation and large-scale deployment in renewable energy and energy storage system projects. In this context, batteries are no longer viewed as a short-term backup solution, but as a long-life infrastructure component required to handle fluctuating loads while maintaining high reliability over many years.

Addionics is an Israeli startup focused on structural improvements to lithium-ion batteries without altering their underlying chemistry. The company’s core technology is based on three-dimensional current collectors that replace flat metal foils with a smart, porous structure offering significantly larger surface area. This architecture improves electrical conductivity within the cell, enables more efficient heat dissipation, extends battery lifespan and supports high-power charge and discharge — all critical characteristics for energy-intensive AI infrastructure.

Under the collaboration, Addionics’ technology will be integrated into the manufacturing processes of PNT Materials, a South Korean company with extensive experience in producing materials, equipment and industrial processes for the battery industry. PNT has long served as an infrastructure supplier to the global battery market and in recent years has expanded into LFP cells and large-scale energy storage applications, with a strong focus on scalability, reliability and cost reduction.

The decision to focus on prismatic LFP cells reflects a broader shift across the energy and AI sectors, where the emphasis is moving away from the pursuit of maximum energy density toward stable, safe and economically viable solutions at infrastructure scale. The combination of Addionics’ three-dimensional battery architecture with PNT’s manufacturing expertise is intended to position energy storage as a foundational pillar of the AI-driven digital economy.

Dr. Moshiel Biton, founder and CEO of Addionics, said that “combining our technological advantage with PNT’s manufacturing capabilities will enable us to deliver high-quality, cost-effective batteries that help accelerate the AI revolution and support the global transition to clean energy.”
