Finnish research opens up new possibilities for Li-ion batteries
- Scientists at the University of Eastern Finland have found a solution to a problem concerning the low electric conductivity of new materials used in Li-ion batteries
- New materials are being developed for the next generation li-ion batteries because the old ones used, such as lithium cobalt oxide, are expensive and difficult to handle.
- One promising material pair is lithium titanate countered by lithium iron phosphate. The raw materials for these components are readily available, safe to use and easy to dispose of or recycle.
- “The electric conductivity problem can be solved by producing nanosized, high surface area crystalline materials, or by modifying the material composition with highly conductive dopants. We have succeeded in doing both for lithium titanate (LTO) in a simple, one-step gas phase process developed here at the UEF Fine Particle and Aerosol Technology Laboratory,” says researcher Tommi Karhunen.
- “The electrochemical performance of Li-ion batteries made out of the above mentioned material is very promising. The electrochemical properties were studied in collaboration with Professor Ulla Lassi’s group from Kokkola University Consortium Chydenius.
