Lithium-Ion Batteries

open access: yes, 2022
Highly concentrated electrolytes offer enhanced energy-density for aqueous batteries, but the high salt concentration presents formidable challenges for practical implementation. Now, an electrolyte has been designed that has a substantially reduced salt concentration while still enabling high-performance batteries.

Anti-Kasha triplet energy transfer and excitation wavelength dependent persistent luminescence from host-guest doping systems

open access: yesNature Communications, 2023
Anti-Kasha’s process in organic luminogens has attracted many attentions since its discovery. However, only limited examples of anti-Kasha’s rule have been reported and anti-Kasha triplet energy transfer (ET) is even less-touched.
