Understanding wettability for improved Li-ion batteries

Li-ion batteries have been widely used in various electronic devices such as toys and other portable devices. There is, however, an increasing demand for better performance and higher energy density batteries due to the increase in the electric vehicle market. Wettability plays an important role in both lithium-ion battery manufacturing as well as performance and safety of the batteries. Studying the wettability at different stages of the manufacturing process is thus crucial and will deepen the understanding needed to produce even better batteries in the future.

Key capabilities to support Li-ion battery manufacturing and performance

Maximize Li-ion battery performance

Measure the wettability between the electrolyte and electrode using the optical tensiometer. 

Speed-up Li-ion battery manufacturing

Use a force tensiometer to monitor the electrolyte uptake into electrode material.

Reduce the safety risks in Li-ion batteries

Measure the wettability between the separator and the electrolyte with an optical tensiometer.

What can you achieve with tensiometers

  • Optimize the wettability between the active material in the slurry and the solvent for proper dispersion 
  • Improve adhesion between copper/aluminum and electrode slurry for better battery performance
  • Evaluate the effect of calendering on electrode wettability
  • Optimize the surface tension of electrolyte for improved electrode and separator compatibility

  • Measure electrolyte uptake on electrode material to ensure shorter manufacturing times
