Volklec

UK Battery Cell Manufacturer

THE ONLY UK-manufactured battery cells for an electrified future

Proven technology. Sovereign supply. A partner built for the long term — delivering independence as a strategic advantage for industries that cannot afford to wait.

Our Purpose

UK-manufactured battery cells for an electrified future

Electrification is the defining industrial transition of our era. The supply chains that power it are fragile, opaque and difficult to control. Volklec exists to change that — building the critical national capability the UK needs, right now.

What We Stand For

Reasons to
work with Volklec

Innovator

Redefining Battery Cell Manufacturing

We are not retrofitting old thinking. We are building UK cell manufacturing from the ground up — combining proven global chemistry with fresh industrial ambition and full process control.

Enabler

Delivering Independence as a Strategic Advantage

Geopolitical uncertainty is a cell-supply risk. We remove it. UK-manufactured cells give our customers control over origin, compliance and continuity — on their terms.

Proximity

Bringing Value Closer to the Market

Domestic manufacturing means shorter lead times, simpler audit trails and supply chains that respond faster. We are here — on the ground, in the UK, building alongside you.

Catalyst

Igniting the Right Capability Across Multiple Industries

From defence and aerospace to marine, mobility and industrial systems — the transition to electrification is happening across every sector. We are the cell partner built for all of them.

Cornerstone

Providing a Critical Link in Supply Chain Resilience

Battery cells are strategic infrastructure. Volklec provides the sovereign domestic link that defence programmes, critical industries and electrification roadmaps all depend on.

"Proven technology, trusted by leading brands, instrumental to industry"

Our 21700 lithium-ion cells are manufactured under exclusive licence from an established Asian manufacturer active since 2009 — combining decades of proven cell chemistry with UK production, control and full process knowledge transfer.

Independently tested by About: Energy and Cognition Energy. Available now for validation, integration and programme development.
