Exploring Battery Performance Beyond Room Temperature
Most rechargeable battery testing focuses on room temperature, but real-world applications often expose batteries to hotter or colder environments. To design safe, longer-lasting rechargeable batteries, Md Zawad Hossain and the team at Wichita State University investigated how promising battery materials behave in those hotter and colder conditions.
For this purpose, the team used Niobium diselenide (NbSeâ‚‚), which is a transition metal dichalcogenide with advantageous properties such as large interlayer spacing, inherent conversion-type charge storage, and cycling stability making it a promising material for next-generation sodium-ion (SIBs)Â and potassium-ion batteries (PIBs).
Using the Squidstat Plus & Squidstat Prime, the team evaluated NbSe₂ at 15 °C, 25 °C, and 45 °C, by examining electrochemical activity, ion transport kinetics, and ion storage mechanisms.
Reaction resistance increases during phase transitions at lower temperatures, slowing interfacial kinetics.
Equilibrium potentials shift as temperature decreases.
Strong cycling stability over 1,000 cycles (1 A/g) at both 15 °C and 25 °C for SIBs and PIBs.
By directly correlating temperature to electrochemical behavior, the study provides valuable guidance for designing safer, more reliable next-generation SIBs and PIBs using NbSeâ‚‚.
