From top left, clockwise:

1) BATTERY: An ion chemical potential difference across the cell electrolyte enables electrical work to be done on an external load (discharging) or energy storage (charging) at room temperature (energy conversion/storage)
2) CHEMI-RESISTIVE SENSOR: Gas adsorption by electron-withdrawing species increases the measured n-type resistance in sensor material with high surface-to-volume ratio, enabling gas sensing (environmental monitoring)
3) SOLID OXIDE CELL: High temperature, clean, and efficient electrochemical power generation from various fuels, or chemical fuel production via electrolysis within the same reversible device (energy conversion/storage)
4) PHOTOELECTROCHEMICAL CELL: Electrons and holes, generated by incident sunlight in semiconductor, separate under internal electric field and drive the water splitting reaction generating fuel and oxygen (energy storage)
5) BIO-IONICS: Interactions between biological cells and redox active nanoparticles have implications for toxicity and antimicrobial applications; additionally, biological ion transport suggests possibilities for biomimetic solid state ionics (health)
6) PHOTO-CHROMICS: reversible voltage-driven ion motion changes optical absorption of window, giving control of light transmission with applications to smart windows and displays (energy conservation)
7) MEMRISTOR/ RESISTIVE SWITCH: voltage-driven changes in resistance state owing to formation of conductive regions or filaments enable new applications in memory and computing (nanoelectronics)
8) SOLAR THERMOCHEMICAL CELL: solar heating causes mixed conductor to lose oxygen; upon cooling materials are thermodynamically driven to pick up oxygen, for example turning water into useful fuel (energy storage)


Nobel prize 2019 to the chemistry of Li ion batteries


The International Society for Solid State Ionics (ISSI) congratulates the laureates for 2019 in chemistry,

John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino


The Nobel prize in chemistry for 2019 was awarded to the three laureates for their contributions supporting the development of lithium-ion batteries. We know the three as outstanding scientists, colleagues and friends, who have contributed actively in a range of areas and for the benefit of the solid-state ionics and electrochemistry communities and more broadly the health of our planet. Their work has, and will continue to have, immense impact towards supporting  a sustainable planet, and the prize is well and long deserved. On behalf of the International Society for Solid State Ionics (ISSI) and its membership, I gratefully and proudly congratulate the three laureates on their award of the Nobel Prize in Chemistry 2019.
