Seeing Battery Solutions Move to Assess the Health of Batteries
Organic redox-active molecules (redoxmers) are popular for flow battery fluids. Their structural variability comes with other properties that may be tailored for function. We discovered that fluorescence emission can be engineered into redoxmers, which allows real-time tracing of species crossover in a liquid flow cell, a key state of health (SOH) metric. The extracted permeability values show dependence on composition of electrolytes such as salt or redoxmer concentrations. Read More

Salt nanoconfinement in zirconium-based metal organic frameworks leads to pore-size and loading-dependent ionic conductivity enhancement
The nanoscale confinement of [NEt4][TFSI] in three isostructural MOFs enhanced the conductivity of composites relative to neat [NEt4][TFSI] by up to a factor of 50. The conductivity increases with the increase in pore size and maximum conductivity was achieved with a salt loading slightly less than that required for complete filling of the MOF pores. Read More
