Based on the measurement data, it is possible to estimate the lifespan for up to 10 years under normal usage conditions.
The AKTS company's "Kinetic Analysis Software" determines the degradation reaction model from retention test data and charge-discharge cycle test data for lithium-ion batteries, and estimates lifespan using the obtained reaction equations and kinetic parameters such as activation energy. Additionally, it is possible to estimate lifespan under everyday usage conditions for up to 10 years based on measurement data from charge-discharge cycle tests and retention tests. **Features of AKTS Software Lifespan Estimation Function:** - Cycle tests and retention tests have temperature conditions of three or more (e.g., 25, 45, 55°C). - The number of measurement data points (capacity retention rate) totals over 40. - The degradation reaction equation for calendar life is calculated from the capacity retention rate obtained from retention tests. - The degradation reaction equation for cycle life is calculated from the capacity retention rate obtained from cycle tests. - By setting the temperature conditions, time, and number of charge cycles for the degradation reaction model equations 1 and 2, it predicts the lifespan estimation curve under actual usage conditions. - The lifespan prediction curve can calculate a prediction range of 95%. - The prediction range depends on the measurement data. *For more details, please refer to the PDF document or feel free to contact us.*

Company information
Our company works in the field of thermal safety evaluation to prevent thermal runaway accidents involving chemical substances. To achieve this, we analyze reaction kinetics parameters from thermal measurement data of a few milligrams of chemical substances and provide a measurement and analysis system that enables thermal safety evaluation when the chemical substances are scaled up to kg to 1000 kg. Additionally, we offer an evaluation system that combines isothermal microcalorimeters (IMC) for lithium-ion batteries and DSC with AKTS analysis software, allowing for comprehensive measurement of the entire battery.
