On August 7, at the "3rd Future Battery Materials and Technology Outlook Seminar" hosted by the Chemical Economic Research Institute at the Federation of Korean Industries Hall in Yeongdeungpo-gu, Seoul, Enchem's Head of Technology Research Center, Jang Youngcheol, gave a presentation on "Electrolyte Technology and Development Trends for Secondary Batteries."

In his presentation, Jang emphasized that the development of lithium-ion batteries is progressing in four main directions: high capacity, low cost, high safety, and high performance. He stressed that electrolyte research must align with these development directions, as electrolytes are the most crucial raw material in electrolytes.

The development of high-capacity batteries aims to improve energy density, thereby increasing the driving range of electric vehicles. The main research targets are nickel-rich high-voltage cathode materials, high-capacity silicon anode materials, and metal lithium anodes.

Jang explained, "High-capacity silicon anode materials have a higher specific capacity compared to graphite and are very advantageous in terms of cost due to abundant resources. However, they face challenges such as significant volumetric expansion during charging and discharging, and excessive generation of high-temperature gas. Metal lithium can greatly increase energy density per weight, but dendritic growth becomes a problem when lithium ions are reduced to lithium metal." He added, "These issues must be minimized at both the material and electrolyte stages."

Jang also discussed lithium iron phosphate (LFP), lithium manganese iron phosphate (LMFP), and lithium manganese-rich (LMR) cathode materials, as well as the dry electrode process, which are widely used due to their competitiveness in terms of low cost. He explained the technical challenges that need to be addressed at the material stage and those that must be solved at the electrolyte stage, helping participants gain a deeper understanding.

Additionally, Jang predicted, "Sodium-ion batteries (SIB) will see increasing development demand in the future due to their ease of resource procurement, low cost, environmental friendliness, and relatively high safety." He also presented experimental results on high-safety electrolyte technology, which can prevent fire risks and thermal runaway?issues often cited as obstacles to electric vehicle adoption.
