Cathode vs Electrolyte: Decoupling the Origins of Degradation in High-Voltage Ni-Rich Lithium-Ion

Abstract Raising the upper cutoff voltage and deploying Ni-rich layered oxides (e.g., NMC811) are promising routes to higher lithium-ion cell energy density. However, the origin of degradation remains unclear at high-voltage operation. We propose using a cycle-relevant scan rate...

Residential indoor air monitoring to assess long-term exposure to air pollution in susceptible populations for epidemiology: overview and early findings

While there has been accumulating evidence of the association between long-term exposure to air pollution and various health endpoints, most epidemiological studies relied on ambient air pollution which showed substantial deviation from indoor. This difference could lead to biase...
