Redefining battery architecture

Addionics is a Smart Metals manufacturer transforming the battery cell from a stack of isolated layers into a unified electrochemical system through Smart 3D Porous Current Collectors. These copper and aluminum current collectors improve battery performance across cell formats and chemistries, from today's lithium-ion systems to emerging battery technologies.

Addionics is the first company to unlock a scalable, cost-effective production process for both anodes and cathodes: connecting electrode architecture with battery performance and manufacturing optimization.

01How the architecture works

Conventional current collectors are flat, solid metal foils. Addionics replaces them with a porous, ion-permeable metal architecture that creates new pathways through the electrode and changes how the cell transports energy, ions, electrolyte, and heat.

  • Improved ionic and electrolyte transport

    The porous structure creates through-plane pathways for lithium ions and electrolyte, shortening transport distances and supporting more uniform electrochemical activity across the cell.

  • Lower internal resistance

    The interconnected metal structure improves electrical conductivity and lowers contact resistance, supporting faster charging, higher power, and reduced heat generation.

  • Higher active material loading

    Improved adhesion and transport enable thicker electrodes and higher active material loading, increasing energy density without increasing cell size.

  • More uniform current, heat, and salt distribution

    More balanced transport and current distribution reduce localized hot spots and support improved electrolyte salt homogeneity during repeated cycling.

03The platform

Application-specific design using AI

Addionics' patent-pending AI platform uses advanced structural modeling and machine learning to design the optimal current collector architecture for each application.

By analyzing how different structures influence battery performance at the cell and electrode level, the platform identifies the optimal geometry based on chemistry, cell format, use case, and system-level requirements.
