Austen Angell’s Legacy in Electrolyte Research
This is an article to remember the late Prof Austen Angell (1933~2021) Prof Angell was the guru in non-crystalline solid materials, an authority in glass-transition phenomenon. His brief and tangential interest in battery electrolytes in 1990s discovered the abnormal ion-solvation behavior at high concentrations, which… Read More

Mesolytic Cleavage of Homobenzylic Ethers (HBEs) for Programmable End-of-Life Function in Redoxmers
We successfully added an end-of-life function into redoxmers whereby deconstruction is controlled by a redox-triggered mesolytic cleavage of HBE linkages. Using a combined experimental and computational approach, we thoroughly investigated HBE degradation mechanisms, fragmentation pathways, electrochemical properties, and programmable deconstruction of HBE-containing redoxmers from an interface and in bulk solution.

Next Generation Ca-Ion Cathodes based on Molybdenum Oxide
Calcium-ion energy storage systems are relatively unexplored mainly due to lack of available active materials. Building on our recent successes with high voltage phosphate materials we have expanded the available Ca-ion cathode materials to the high-capacity layered oxide MoO3. Read More
