> Addionics changes the battery’s architecture itself: Smart 3D Current Collectors that turn a stack of layers into one unified cell. Chemistry-agnostic, drop-in.

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.

## What the technology does

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.

## Common questions

### What is a Smart 3D Current Collector?

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.

### Which battery chemistries does it work with?

Smart 3D Current Collectors are chemistry-agnostic. They can be optimized for today's leading battery chemistries and for the next generation of energy-storage technologies, from lithium-ion systems to emerging battery technologies.

### Does it require new manufacturing equipment?

No. It is a drop-in change that integrates with existing coating and production lines through a roll-to-roll manufacturing process, and is compatible with all battery chemistries and formats.

### How much does it improve energy density?

Higher electrode loading increases energy and power density without increasing the cell footprint, for a measured improvement of up to 15% in energy density and up to 50% in cycle life.
