ENEREVER Battery Solution will develop a next-generation graphene separator for electric vehicles within this year. Graphene separatorsare a new material specialized for rapid charging of electric vehicles. When applied to electric vehicles, the charging speed is increased to less than 18 minutes.
ENEREVERBattery Solution announced on the 28th that it plans to participate as a supplier in a national project to develop next-generation graphene separators. This project is a next-generation materials and parts technology development projectrun by the Ministry of Trade, Industry and Energythat connects demand and supply sources. ENEREVERBattery Solution is developing graphene separator products to be supplied to U&S Energy, a domestic electronic parts company. The company will receive the technology transfer from the Advanced Institute of Convergence Technology, Seoul National University, and Kyungpook National University.
Separatorsare essential materials that enhance the safety of electric vehicle batteries and increase output. If the separator is thicker, it is less likely to get torn, increasing safety. On the other hand, a thick separator interferes with electron movement and degrades battery performance.
ENEREVER Battery Solution uses graphene (rGO) conductive material-based materials to enhance the safety and performance of the separator. A graphene conductive material was added along with boehmite to the ceramic coating base material to enhance the safety of the separator. The electron transfer speed was increased while preventing the deformation of the separator.
The charging speed of electric vehicles using graphene separators can be reduced to a few minutes. When charging an electric vehicle using a 100kW-class fast charger, the charging speed can be reduced from 1 hour to less than 18 minutes.
ENEREVER Battery Solution plans to develop a functional graphene thin film composite separator product by the end of this year. An official from ENEREVER Battery Solution said, “Once the separator development is completed, it can be appliedto the electronic parts of all kinds of products," adding, "We will cooperate with UN Energy to introduce products that can be mass-produced in 2025."
The national project is worth 4.1 billion won. The process for selecting a supplier is expected to be finalized soon. ENEREVER Battery Solution aims to strengthen national competitiveness by developing next-generation separator products in cooperation with Advanced Institute of Convergence Technology, Seoul National University, and Kyungpook National University.
Sang-ki Shin, CEO of ENEREVER Battery Solutions, said, "We will lead the global electronic parts industry to the era of carbon neutrality by developing future technologies for eco-friendly separator materials."
