Lithium ion secondary battery, a technology of the future

Battery has emerged as a core technology that can lead the era of the fourth industrial revolution. The batteries of smartphone, tablet PC, laptop and electric vehicle mainly use lithium ion secondary battery. Therefore, development of related technologies is very important. Lithium ion secondary battery is also expected to grow as one of the Korea's core industries in the future, so a lot of related technologies have been developed. A lithium metal ion battery with doubled energy density was developed by Korea Institute of Science and Technology. And it can maintain over 80% of its initial performance even when repeating charging and discharging over 1,200 times. Adding an artificial solid-electrolyte interphase with a thickness of thousands of nanometers to the surface of lithium is the core of the lithium metal ion battery. When applying elastic electrodes to lithium ion secondary battery, the battery can maintain its property safely even when the length is increased by more than 30%. Moreover, a lithium ion secondary battery which can be charged rapidly has been developed. When installing the battery to the device, it can be charged rapidly and conveniently in about 3-10 minutes. By using an anode material of lithium ion secondary battery, it can be charged rapidly and used for a longer period of time. We introduce the outlook for the battery industry, which has expanded rapidly along with the rise of lithium ion secondary battery.

Application of ultrasound to daily lives

Ultrasound refers to the sound waves with frequencies that are higher than the audible limit of humans. In the past, it was mainly used for medical devices and military equipment. However, it has been introduced to a wide range of areas related to people's daily lives. Home appliances which have implemented the ultrasound technology have been introduced. Dishwasher is one of the examples and ultrasound can make vibrations. Bubbles that are made through vibrations can clean the leftover food. And it can wash the dishes spotlessly only with water, without a chemical cleaner. The pre-order system, which has been widely used in various sectors, has also implemented ultrasound technology. The ultrasound generated from Beacon installed at the store can provide the exact location of customers. Medical sector is one of the areas that is closely connected with ultrasound. However, patients could get treatments only by visiting a hospital. And a domestic research team has developed an ultrasound-based diagnosing robot to tackle the challenge and provide a remote medical treatment. We look into ultrasound technologies, which have been closely connected with people's daily lives.

Ere&Elpis, paving a new path for fire doors

Fire door is usually constructed between the indoor spaces and stair halls. And it can prevent the spread of flames and poisonous gas in case of fire. Along with the increased risk of fire because of the growing number of high-rise buildings, concerns have been raised over the loss of lives as well as property damage. Therefore, fire door has grown in significance. Ere&Elpis is a leading maker of fire doors with improved fireproof and insulation effects as well as sensuous and sophisticated designs. The company has designed and manufactured the products based on its own system. All the frames and components necessary for fire doors can be produced with the production facilities of the company. The firm has introduced automated equipment to the production lines that require sophisticated works. And it has contributed to increasing the degree of completion. Silk printing is carried out by using a silk printing machine and silk printing heating furnace of the company. Fire doors with a variety of colors and designs are manufactured by the company. As diversified designs can be printed, the design can be changed according to the requirements of the clients. Moreover, the advanced manufacturing skills of the company have gained recognition in the global market. And overseas buyers make a visit to the manufacturing plant and check the production facilities. We explore Ere&Elpis, which has strengthened its position in the global market by developing unique and differentiated technologies for the manufacturing of fire doors.
