We estimate battery life from cycle test and retention test data of lithium-ion batteries.
AKTS Corporation's Thermokinetics can predict lifespan from accelerated test data using reaction kinetics and the Akaike Information Criterion. From the capacity retention data of retention test data and charge-discharge cycle test data, we derive the reaction model equations for calendar life and cycle life. Using the reaction kinetics parameters such as the activation energy obtained from the derived reaction model, we can determine the capacity retention curve under actual usage conditions for lithium-ion batteries. 【Features】 ■ Temperature levels: 3 examples: 20, 40, 55°C capacity retention data Can estimate capacity retention for 10 years from 30 to 40 measurement data points ■ The estimated capacity retention curve is provided with a 95% prediction interval using the bootstrap method ■ Degradation reaction equations and activation energy can be determined *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.
