This technology is about the production of oxide/polymer hybrid solid electrolyte membranes using composite ceramic materials and all-solid-state lithium secondary batteries.
LLZO used in all-solid-state batteries has the problem of reacting with moisture and carbon dioxide at room temperature to generate Li2CO3 on the surface, resulting in Li loss and reduced ionic conductivity. To solve these problems, this technology proposes a hybrid electrolyte of a ceramic composite composition for secondary batteries using LALZO (Li6.28Al0.24La3Zr2O12) and h-BN (Hexagonal Boron Nitride) as active ingredients.
This technology significantly solves the problems of lithium loss, reduced ionic conductivity, and reduced interfacial stability, improving electrochemical properties, and lithium ions applied with existing organic liquid electrolytes. It is expected that it can replace batteries (LIBs).

The present invention relates to a stave and to the structure inside a blast furnace that produces molten iron while charging coke and iron ore.
If the cooling pipe of the stave is damaged due to the inevitable shock inside the blast furnace, and the stave cooling pipe is damaged, it must be repaired immediately. However, due to the high pressure and high temperature environment inside the blast furnace, it is difficult to repair the stave without stopping the blast furnace, so manufacturing costs increase as the operation of the blast furnace is stopped to repair the stave. This technology seeks to propose a stave that can automatically repair damaged cooling pipes without stopping the operation of the blast furnace.
This technology repairs damaged parts of cooling pipes in real time, allowing staves to be repaired without stopping the operation of the blast furnace, thereby minimizing economic losses and contributing to the safety and lifespan of the blast furnace, thereby improving productivity in the steel industry.

Among secondary batteries, lithium-ion batteries (LIB) using an anode material with a layered structure have the highest energy density, so NCM batteries, which are ternary batteries of nickel (Ni), cobalt (Co), and manganese (Mn), are widely used. However, due to limited availability and high prices, research on Li2MnO3 (LMO), an overlithiated layered oxide (OLO) material, is being conducted. Although progress was being made, it had the disadvantage of low lifespan stability. To solve these problems, this technology proposes a method of doping iron to reduce costs and improve structural stability and rate characteristics.
The cathode active material of this technology does not use any expensive cobalt or nickel in Li2MnO3, but dopes it with cheap and eco-friendly iron. It is a groundbreaking technology to be used in the Iithum battery industry as it has cost reduction effects and excellent performance with capacity and long-term cycle stability as much as existing LiNiMnCoO2 (NCM) batteries.

This technology is about a truck equipped with a boat tail to reduce air resistance and improve driving stability.
Fuel costs, which account for the largest cost among logistics costs, increase or decrease depending on various conditions, and air resistance has a significant impact on the fuel efficiency of trucks. This technology effectively controls the flow at the rear of the car body, reducing air resistance and flow noise, and aims to provide a boat tail for trucks and a truck equipped with a boat tail that can improve driving stability.
The boat tail using this technology reduces the size and strength of the recirculation area formed at the rear of the car body by controlling the flow separation that occurs at the rear of the vehicle, thereby dramatically increasing driving stability and reducing vibration by reducing the influence of lateral force applied to the truck. The possibility of damage to goods due to vibration during transportation can be minimized.
This technology was developed through support from the Korea Transport Institute's research project on air resistance and air vortex reduction devices to reduce fuel during truck operation.
This technology involves producing a natural sourdough starter by coating and fermenting rye dough with nuruk (fermentation starter) dough to obtain a primary ferment, followed by the sequential mixing and fermentation of peanut, olive, and shiitake mushroom powders.
