Battery Index Technology (BATIXT) specializes in utilizing Electrochemical Impedance Spectroscopy (EIS) for material characterization and battery development since the 1950s. EIS is applied in various industries such as corrosion, biosensors, fuel cell development, and sensor development, among others. Through non-destructive testing, EIS offers valuable insights into the properties of battery cells, including internal resistance, charge transfer kinetics, state of charge, electrolyte behavior, aging, and degradation.

BATIXT's EIS technique involves applying a test signal to the battery, tracking voltage and current responses. By analyzing impedance variations with frequency, comprehensive EIS data is obtained and visualized through Nyquist diagrams. The company's focus on Single and Multifrequency EIS allows for in-depth battery characterization efficiently, enabling performance monitoring, internal resistance measurement, and state of health evaluation. BATIXT's EIS solutions provide safe, cost-effective, and non-intrusive measurements to expedite research and development processes in the battery industry.
