Garnet Electrolytes for New Energy Storage Integrated Solutions

Our Strategy 

01 / Synthesis 
02 / Characterisation 
03 / Expertise

Through a variety of solid state and sol-gel synthesis, using renewable bio-polymers such as agar, we research new ways to form lithium garnets at low temperatures in order to deliver commercially viable solid state electrolytes.

We have a vast array of tools available to us, including; X-ray diffraction, X-ray absorption, impedance spectroscopy, large volume cell testing and have regular access to synchrotron time, including pair distribution function and XAS. We are also able to draw on the extensive experience of the academic staff in our team.

The expertise offered by the genesis project team has enabled our low temperature synthesis to be scaled up and formation of dense electrolytes via cold sintering. We are also exploiting dry room synthesis/processing of electrolyte membranes, which is industrially scalable.


Lithium Garnets


Solid state batteries are the next leap in energy storage and will offer high energy density batteries with high-performance electrode materials. These batteries will also be non-flammable, non-toxic and recyclable.

The need for a solid-state electrolyte (SSE) for these batteries is of ever-increasing importance and the lithium garnet type materials, following the formula A3B2Li3+xO12 (0≤x≤4), are uniquely positioned amongst SSEs, offering high ionic conductivity and a wide electrochemical window.


We have over thirty years’ experience in solid ion conductor research, thirteen of which have involved study of the Lithium garnet system. Therefore we are uniquely positioned to take on the task of forming a viable commercial route to lithium garnet production.


This includes extensive research into lowering the processing temperatures, enhancing conductivity and actively investigating practical ways to overcome interfacial resistance between the electrolyte and electrode.


Our project team have found new ways to decrease the garnet synthesis temperatures by over 400°C and, in some cases, without the need to protect from aluminium exchange from the crucible. We have also developed strategies to noticeably decrease the interfacial resistance between electrode/electrolyte for these garnet systems.


We are currently looking at novel methods to reduce garnet electrolyte membrane preparation to 300 °C in a full cell device which is also designed for recycling, which can be recycled through low cost aqueous routes.
