Solid-state battery research · Sweden

Engineering the solution, not just the materials.

AetherGrid is a Swedish deeptech company developing advanced architecture for solid-state battery systems. We address technical bottlenecks at the system level that conventional materials development leaves untouched.

Approach

Most solid-state research optimises bulk materials. We work elsewhere.

Peer-reviewed research consistently identifies system-level bottlenecks as central limitations for solid-state battery commercialisation. Yet the field treats these as downstream consequences of material selection — rather than as separate design domains in their own right.

01

Architecture as design domain

Treating system architecture as a primary engineering discipline rather than a downstream consequence of material choices. The result is targeted at bottlenecks the field already knows exist but rarely addresses head-on.

02

Designed for low-temperature performance

Sub-zero performance treated as primary design parameter rather than secondary application. Critical for Nordic climates, defence applications, and outdoor stationary storage.

03

Compatible with multiple electrolyte systems

The architecture is not bound to a single electrolyte chemistry. Designed to integrate with several types of solid-state and semi-solid systems — complementary to existing material development efforts.

Where we are

Concept formulated. Validation underway.

Intellectual property

Two provisional patents filed with USPTO

Filed January 2026, covering the architectural concept and design intention. Conversion to non-provisional and PCT planned for late 2026.

Priority date · January 2026
Academic collaboration

Pilot validation with Ångström Laboratory

Commissioned research with Professor Daniel Brandell at Uppsala University. Experimental characterisation of interface behaviour across a defined temperature range, with NDA in place.

Funding

Funding process underway

Concept development funding application in preparation for the Swedish Energy Agency (Energimyndigheten), targeting the June 2026 call for business-focused innovation development. Parallel exploration of European deeptech and dual-use programmes.

Business model

Technology licensing

AetherGrid develops the architecture and licenses to battery manufacturers and system integrators. A capital-efficient path that complements existing development trajectories rather than competing on cell production.

License-based commercialisation
Contact

Open to conversation.

We are particularly interested in dialogue with battery manufacturers, system integrators, deeptech investors, and research collaborators with adjacent expertise. If our work is relevant to yours, please get in touch.
