Batteries play a key role in the ongoing shift from the use of fossil fuels towards sustainable transportation and renewable energy production. As an innovative R&D partner, we support you in developing high-performance, lightweight, safe, low-cost and sustainably sourced and manufactured batteries to store renewable energy and power electric vehicles.
Battery research at VTT
We conduct experimental performance testing of cells, modules and packs as well as develop tools for battery system design, battery management and optimal operation to support the development and deployment of the systems.
Our goal is to increase the sustainability of batteries by developing new materials and manufacturing and recycling methods, and by increasing their lifetime and energy density.
We support the development and testing of novel battery materials and manufacturing processes in lab and pilot scale.

Batteries enable sustainable transportation and renewable energy storage
The electrification of harsh-use applications, such as heavy-duty vehicles, non-road mobile machines and marine vessels, provides significant potential for increasing energy-efficiency and performance as well as decreasing local emissions. The benefits of efficient electrification are, for example, improved productivity and user experience and lower total cost of ownership.
In addition, the increasing need for sustainable solutions for stationary energy storage creates opportunities for new battery technologies.
To ensure the sustainability of electrification, we should guarantee ethical raw material sourcing and consider the limitations in material availability. This creates a clear need for efficient recycling and tracking solutions, novel battery chemistries and methods to increase battery lifetime.
Our offering
With our expertise, infrastructure, global connections and business understanding, we can support you with your energy storage needs throughout the value chain. Here are some areas we can make a difference in:
- Requirement specification
- Technology assessment and selection
- Systems engineering
- BMS and energy management
- Testing and validation
- Grid integration
- Battery health monitoring and prognostics
- Lifecycle management
- Sustainability assessment
- Optimisation of battery healthy and lifetime.
In addition, VTT can support the battery sector to test and develop novel battery materials and manufacturing processes, even in pilot scale.
We support research and industry throughout the battery value chain.
The following image describes our main activities in the energy storage field, throughout the whole value chain and in a circular economy fashion.
Applied battery research facilities
We have developed competences and facilities for applied energy storage R&D since 2010. Our research laboratories enable comprehensive experimental work on battery cells, modules and packs, as well as battery management systems and thermal management. These facilities are integrated with dynamometer facilities enabling experimental work not just on batteries, but also on heavy-duty vehicles, drivetrains and engines under the same roof. With our high-power battery emulator, we can test electric vehicle prototypes on the dynamometer even without a real battery installed in the vehicle.
We have also recently built competences for battery safety testing at cell level. Having tested hundreds of batteries, we can provide state-of-the-art knowledge, foresight and experimental research services. The backbone of these services is experimental work combined with modelling capabilities and tools.
Related infrastructure
We have both laboratory and pilot scale facilities where we can print and coat different battery materials and layers.
Next generation batteries and supercapacitors
We develop processes and materials for sustainable next-generation batteries. We specialise in a wide range of battery chemistries, from lithium-ion, sodium-ion and solid-state batteries to supercapacitors.
Our goals are twofold:
- We utilise abundant, bio-based and locally available raw materials, or even waste resources in batteries. This helps you to cope with limited material availability and increases the resilience of supply chains. We have created a process for Na-ion battery manufacturing and testing, and we are also developing biocarbon materials and organic batteries. These batteries are suitable for applications where extremely high energy density is not needed, such as stationary storage.
- We develop processes and materials for solid-state batteries with high energy density. Such batteries are especially suitable for mobility and wearable electronics applications. We minimise the greenhouse gas emissions of solid-state battery production by using energy-efficient processes, such as dry extrusion coating. In addition, we increase the lifetime of the batteries by self-healing methods and stabilising the interfaces.
We offer a platform to test both standard and novel battery processing methods and help you to upscale production using inline inspection methods. We also have the capability to assemble both coin and pouch cells in an inert atmosphere. Our unique printed intelligence facilities and know-how enable the integration of batteries with other components, such as solar cells, sensors and LEDs.
