In this work, we report a family of Li-rich double perovskites where Li-ions are present in both A- and B-sites enabling their ionic conduction and function as battery materials. Tailoring their chemical composition affords both a redox-active anode using W6+ cations and a solid-state electrolyte with high electrochemical stability and compatibility with metallic Li by introducing Te6+. Sharing crystal structure results also in good inter-compatibility! The work has involved a wide range of characterisation techniques including electrochemistry, x-ray and neutron diffraction, x-ray absorption spectroscopy, muon spin relaxation and DFT calculations to shed light into the intercalation mechanism and electronic structures.

In this work, freeze casting technique was employed to obtain 3D porous LLZO solid-electrolyte scaffolds that were infiltrated with NMC-622 cathode material to form thick composite electrodes for all-solid-state batteries. Full text here.

A review paper with the team at NPL has been recently published as Open Access in the journal Batteries. The work summarises past and recent advances in the field of reference electrodes for LiB exploring the advantages, disadvantages and future prospects for their implementation on commercial batteries.

My latest work on a novel Na-rich double pervovskite has been accepted for publication in Chem. Comm. This work comprises the synthesis and characterisation of a novel Na-rich double perovskite with the formula Na1.5La1.5TeO6 with Na ions in both A- and B-sites. The presence of Na ions on both sites enables lower energy barriers for Na-ions diffusion as demonstrated by electrochemical impedance and muon-spin relaxation spectroscopies. Go check it, it is published as Open Access!
