Battery technologies


Batteries play a key role in the ongoing shift from the use of fossil fuels towards sustainable transportation and renewable energy production. In today’s world, we need more high-performance, lightweight, safe, low-cost, and sustainably sourced and manufactured batteries to power the electric vehicles in a sustainable way.

Key facts: Battery research at VTT

VTT can characterize energy storage devices in small and large scale, and develop battery management systems for them

Our goal is to increase the sustainability of batteries by developing new materials and manufacturing & recycling methods, and by increasing the lifetime and energy density

We test and develop new battery manufacturing processes both in lab and pilot scale
