Silicon-anode cell technology

Battery energy density, built for the gigawatt-hour scale.

We engineer silicon-anode electrode technology that enables more energy per battery cell — and builds on the production lines the industry already runs. Higher performance, without a new factory to get there.

The approach

Silicon holds the energy. Scaling it has been the problem.

Silicon stores far more lithium than the graphite anodes in use today — the clearest path to higher energy density. But silicon swells and fractures as it charges, and the usual ways to tame it depend on specialised, hard-to-scale production steps that keep high-silicon cells out of reach.

Volt14 took the other route. We developed a proprietary electrode architecture that holds high silicon loadings stable — across different silicon sources — and engineered it from the bottom up to run on standard production lines. The performance comes from the architecture, not from a new process the industry has to adopt.

What the architecture delivers

High energy density

In projects aiming for 350–500 Wh/kg.
Scalable

Exclusive use of mature processes with established scale-up principles. No specialised processes such as prelithiation or in-house chemical vapour deposition (CVD) to solve silicon’s inherent challenges.
Drop-in

Designed to transfer fully to any standard production line — no process changes, no specialised handling, no needs such as extreme dry rooms.

Two offerings, built on the same architecture.

Anode technology

For cell makers building on their own lines.

Advanced cells

Being qualified today and open for sampling.

Performance figures are shared under discussion. Contact us for specifications.

The EL1 anode production line, with coated copper foil on the roll

EL1 — the architecture, now on a production line.

EL1 is our first anode production line: continuous, roll-to-roll, running the same architecture we designed to drop into the industry’s installed base. Electrodes from EL1 ship to partners for qualification and development. It is the step from a result in the lab to a process that scales.
