Finnish deep-tech company closes funding round to expand production capacity and deliver material samples to customers in wearables, drones and dual-use applications
Tampere, Finland — 23.06.2026 — Pulsedeon Oy today announced the closing of a funding round of approximately EUR 700,000 from Finnish and international family offices, private investors and existing shareholders. The proceeds will expand Pulsedeon’s production capacity and enable the delivery of material samples to customers across Europe, the United States and Asia.
A multi-technology platform for solid-state battery manufacturing
Pulsedeon develops its solid-state cell production technology through a proprietary combination of pulsed laser deposition (PLD), cold spray deposition, thermomechanical processing and advanced cell stacking technology. The company targets ownership of each key technology in this stack, while retaining the capability to integrate third-party processes where appropriate. Its processing solution is fully dry — without the use of binders — providing a sustainable, safe manufacturing process with reduced energy consumption.
This multi-technology approach offers capabilities that competing deposition methods cannot match individually: the ability to produce ultrathin lithium metal and lithium alloy anodes at 1–10 µm — a fraction of the industry standard — combined with precise control of inorganic solid electrolyte and barrier layer thickness, high ionic conductivity, and compatibility with more than 20 battery materials across hybrid, all-solid-state and anodeless architectures. The platform is compatible with both roll-to-roll and sheet-to-sheet production formats, and can be deployed for selected material layers within a cell or for full cell production.
Built on over EUR 7.5 million of technology investment since 2019 — drawing on research from Aalto University, the Universities of Tampere and Oulu, VTT, and leading universities and research institutes across the EU — Pulsedeon holds 11 patent families covering critical process steps across the solid-state battery value chain. The company operates two technology centres in Finland: in Ii, near Oulu, and at Tampere University campus.
What this means for end customers
The practical consequence of Pulsedeon’s technology is dramatically higher energy density within the same or smaller physical footprint — a step change that unlocks new product capabilities across multiple segments.
For wearable devices, higher energy density means longer battery life for the same battery size — or the freedom to use the space freed by a smaller battery to add new sensors, compute power and features. Critically, denser local energy storage enables more capable on-device AI inference, reducing dependence on cloud connectivity in both consumer wearables and military applications where network access cannot be assumed.
For drones, the benefits are directly operational: greater energy density extends flight range, increases endurance, or allows the aircraft to accept higher payload without a weight penalty — whether sensors, communications equipment or mission-specific cargo.
Active customer base across high-value segments
Pulsedeon has established revenue-generating R&D partnerships with leading companies in the wearables, drone, defence and automotive segments. The company participates in four active EU Horizon Europe consortia alongside industrial partners including SAFT, Stellantis, Umicore, Pipistrel, Piaggio Aerospace and Arkema, and top research institutions including Fraunhofer Institute, CEA, CIC, Cidetec, Politecnico di Torino and Uppsala University. BusinessFinland has also supported the company’s fundamental technology development phase. Demand for material samples and dedicated customer programs has to date exceeded Pulsedeon’s production capacity; this funding directly addresses that constraint.
“Our customers are asking for samples and validation programs we currently cannot produce fast enough. This investment expands our capacity to deliver — and accelerates our path to commercial agreements.”
— Jari Liimatainen, CEO, Pulsedeon
The funding round is expected to be supportive for additional non-dilutive public funding instruments. Pulsedeon’s technology is directly aligned with Europe’s industrial strategy for next-generation battery manufacturing, providing a domestically developed process technology platform for a supply chain where European sovereignty is a strategic priority.
