Future all-solid battery, carbon nano material dispersion technology

(Some contents of the monthly magazine)
Because of the solidified particles that make up the all-solid-state battery, the interface between the particles is required to improve performance. Stability is very important. This is the biggest challenge in the process of putting an all-solid-state battery into practical use and must be solved.

Among them, low interfacial stability between the solid electrolyte and the carbon conductive material is included. Solid electrolyte-carbon conductive material The interfacial resistance increases due to interfacial side reactions. As a result, the movement of lithium ions and electrons is hindered, resulting in overvoltage of charging. Occasionally, battery deterioration is accelerated.

The exact cause has not been elucidated. Based on the experimental evidence, carbon nanomaterials with high crystallinity are used as conductive materials. By applying it, the electrochemical side reaction at the interface is reduced, and the formation of the insulating material formed by the side reaction is reduced. can be reduced.

In addition, improved electrical conductivity can be ensured, and thus the performance of the battery can be significantly improved. In that respect, one-dimensional carbon nanotubes (CNTs), known as 'new materials of dreams', are suitable materials. It is considered.

Betterial was one of the exhibitors in Battery Show Europe 2022, the largest battery technology exhibition in Europe, held in Stuttgart, Germany (June 28th to 30th). Betterial attracted many visitors covering many European auto makers and electric vehicle battery manufacturers. We are continuing the dialogue with many of the companies and look forward to future business opportunities.

A joint research paper between our Batterial researchers and Seoul National University was published in the Journal of Electroanalytical Chemistry.
