Battery material that achieves long life and fast charging for medical devices.
Electrode material that achieves a 40% reduction in internal resistance, longer lifespan, and fast charging.
In the medical device industry, as portability advances, there is a demand for both miniaturization of devices and improvements in battery longevity and fast charging capabilities. Particularly in portable medical devices used for patient monitoring and diagnosis, interruptions due to battery depletion are unacceptable, making a reliable power source essential. Our binder-free electrode materials address these challenges by reducing internal resistance by 40% and doubling the charge-discharge cycle life. 【Expected Applications in Medical Devices】 > Long-life Devices Batteries for pacemakers (currently in prototype development) Power sources for implantable medical devices > Fast Charging Devices Portable diagnostic devices (such as blood glucose meters and electrocardiograms) Wearable biometric monitoring devices Portable devices for home healthcare 【Benefits of Implementation】 - Extended battery operating time - Reduced charging time - Contribution to miniaturization and weight reduction of devices
basic information
**Advantages of the Developed Carbon Nanotube (CNT) Electrode Technology** > No resin binder By forming electrodes without adhesives (binders), CNT significantly reduces internal resistance and improves the energy efficiency of devices. It is also possible to utilize existing manufacturing equipment as is. > Suppression of heat generation and reduction of charging time The reduction of internal resistance suppresses heat generation, enabling rapid charging at ten times the conventional speed. Additionally, it reduces the risk of thermal damage to biological tissues compared to traditional methods. > Environmentally friendly dispersion technology CNT can be dispersed in water or organic solvents without the use of dispersants or surfactants, simplifying the manufacturing process and reducing the use of harmful chemicals. **Our Strengths** Based on the unique technological capabilities and quality control systems accumulated over many years in the manufacturing of electrical wires, gas equipment, instrumentation, and environmental system equipment, we have built a solid track record in the industrial infrastructure sector. Leveraging the strengths developed in industrial applications that require high reliability and safety, we will provide value across a wide range of markets, including the battery industry such as lithium-ion batteries and capacitors, as well as energy, aerospace, medical devices, industrial machinery, and IoT devices, by developing next-generation materials.
