Our company provides ultra-long lifespan technology that enables electric vehicles (EVs) to travel 1 million kilometers. "Ultra-long lifespan batteries" are designed to establish foundational technology for achieving ultra-long lifespans (more than five times the current lifespan). This technology can be considered not only for EVs but also for energy storage systems (ESS) and industrial applications. Please feel free to contact us when you need assistance. 【Sample Specifications】 <Stacked Laminated Type> ■Nominal Capacity: 10, 11Ah ■Energy Density: - <21700 Cylindrical Type> ■Nominal Capacity: 3.0, 3.4Ah ■Energy Density: 500-520Wh/L *For more details, please download the PDF or feel free to contact us.

Our company is advancing the development of materials and battery/operational technologies focused on battery lifespan. The CFP, which is one of the components of LCA (Life Cycle Assessment), has been incorporated into the European Battery Regulation, and efforts towards CFP will be accessible through the battery passport, becoming a direct evaluation target. Our technology contributes to reducing CFP through the ultra-long lifespan of cells and maximizing warranty periods through diagnostic technology. [Expectations for ultra-long lifespan technology from the perspective of CFP] - Reduction of CFP through the ultra-long lifespan of cells (5 times the usage period ⇒ CFP 1/5) - Maximization of total energy consumption through optimal control - Maximization of warranty periods through diagnostic technology, etc. *For more details, please download the PDF or feel free to contact us.

Our company offers a service to assess the limits of batteries. Understanding the limits of batteries, such as primary and secondary degradation in durability, and conditions like smoke or fire during thermal runaway, is important to know the acceptable conditions and levels. Without being swayed by evaluation results, battery engineers make judgments based on mechanisms, and with an understanding of these mechanisms, they find solutions within the limits. 【Diagnosis Contents】 ■ Charging (Temperature, Rate) ■ Heat ■ Durability ■ Safety *For more details, please download the PDF or feel free to contact us.

We would like to introduce KRI technology for Level 4 battery digital twins. The capabilities of Level 4 (Living) include updating and adapting predictive models based on operational data. Applications are anticipated for virtual sensors that optimize predictive operations for any operational scenario and adapt to the environment. Our company will maximize system performance and enhance safety and reliability through various simulations and degradation prediction technologies applicable to any operational scenario. [KRI Technology] - Various simulations (current, voltage, reaction dispersion, heat generation, etc.) - SOH diagnostic technology, sensing technology - Degradation prediction technology applicable to any operational scenario - Analysis of operational data through data assimilation technology - Updating predictive models *For more details, please download the PDF or feel free to contact us.

Our company is committed to developing the necessary technologies for mobility batteries to realize a mobility society that considers people and the environment. We aim to create long-lasting and highly reliable batteries that can be used "longer" and "safer," as well as high energy density and fast charging solutions to make them "smaller" and "easier to use." Furthermore, we are also pursuing operation, prediction, and reuse for "appropriate utilization." [KRI's Vision for the Battery World] - High energy density and fast charging that are "smaller" and "easier to use" - Long-lasting, highly reliable, and safe batteries that can be used "longer" and "safer" - Consideration for resources and the environment through recycling, process reduction, and elimination of Co, Ni, and F - "Appropriate value judgment" through diagnostics (SOH, SOS) - "Appropriate utilization" through operation, prediction, and reuse *For more details, please download the PDF or feel free to contact us.

Our company is working on the development of battery technology that enables 5-minute charging. Currently, EV charging takes 15 to 30 minutes and faces challenges such as reduced lifespan and lithium plating. To achieve 5-minute charging, it is necessary to address these issues. Our company is pursuing the realization of 5-minute charging through various approaches, including electrode technology, diagnostic technology, and analytical technology. 【KRI's technologies that enable 5-minute charging】 ■ Electrode technology ■ Analytical technology ■ Diagnostic technology *For more details, please download the PDF or feel free to contact us.
