LG Energy Solution and SK On will each unveil batteries featuring new technologies at ‘InterBattery,’ the largest domestic exhibition, held on the 6th. As competition intensifies, the focus is on cost and efficiency.

According to industry sources on the 4th, LG Energy Solution will reveal its pouch-type CTP (Cell to Pack) technology for the first time at InterBattery. Cell to Pack technology eliminates the module stage in traditional battery configurations and assembles cells directly into the pack. It is characterized by increased energy density and reduced battery weight and cost. By reducing the components that make up the pack, manufacturing costs are also lowered. The pouch-type Cell to Pack developed by LG Energy Solution maintains the lightweight characteristics of pouch cells while enhancing pack rigidity and applying heat transfer prevention technology to improve safety.

SK On will introduce the ‘SF+ battery,’ which shortens fast charging time from 18 minutes to 15 minutes. By placing high-capacity silicon and low-resistance graphite in the anode material that determines battery charge and discharge speed, the lithium-ion migration distance is reduced and migration speed is increased. The high-capacity silicon improves migration distance, while the low-resistance graphite enhances migration speed. They will also present an upgraded version of the LFP (Lithium Iron Phosphate) battery, which had been criticized for performance degradation in cold weather. The ‘Winter Pro LFP battery’ increases charging capacity and discharging capacity at low temperatures by approximately 16% and 10%, respectively, compared to existing LFP batteries.

Samsung SDI plans to introduce the development status and specific mass production plans of all-solid-state batteries, known as the ‘dream battery.’ POSCO Holdings will participate in the exhibition at the group level to commemorate the first year of commercialization of lithium and nickel, showcasing the entire value chain from ▲materials ▲components ▲to used battery recycling.

‘InterBattery 2024’ will be held for three days from the 6th to the 8th at COEX in Gangnam-gu, Seoul. This event is expected to be the largest ever, with 579 companies, 1,896 booths, and 75,000 visitors participating.
