The battery industry is set to unveil a bunch of new technologies at Interbattery 2024, Korea’s largest secondary battery industry show.
LG Energy Solution will take the wraps off its cell to pack (CTP) product at InterBattery 2024 which will run from Feb. 6 to 8 at COEX in Seoul.
Cell-to-pack technology enables more cells to be packed into an electric vehicle battery by omitting the module stage that covers cells, modules, and packs. It is considered a key technology in the electric vehicle battery market where price competitiveness is becoming increasingly important as it can reduce battery weight, boost energy density, and reduce cost.
A pouch-type cell-to-pack battery that LG Energy Solution will introduce has increased pack rigidity and enhanced stability with thermal transfer prevention technology compared to existing products. LG Energy Solution increased its price competitiveness by reducing pack components and simplifying the production process.
LG Energy Solutions will also unveil compact high-voltage mid-nickel pouch cells for the first time at the show.
Mid-nickel NCM batteries are a cost-saving product that reduces the proportion of nickel compared to high-nickel NCM batteries. LG Energy Solution has succeeded in realizing high voltage with mid-nickel batteries, which have lower energy density due to lower nickel content, thus securing both efficiency and price competitiveness. The Korean battery giant also plans to develop medium and large-sized mid-nickel pouch cells and supply them to automakers.
SK on will have a booth with the slogan “Speed On,” which means to accelerate its growth, and will put Advanced SF Battery, a high-nickel NCM battery with a fast charging function, front and center. Advanced SF Battery has a 9 percent increase in energy density compared to original SF Battery while maintaining a fast charge function.
Higher energy density boosts anode resistance, which leads to longer charging time. But SK on has overcome this by reducing cathode resistance through a special coating process and shortening the path of lithium ions through an anode alignment process.
SK on will also unwrap SF+ Battery, which uses high-capacity silicon and low-resistance graphite to dramatically reduce distances traveled by lithium ions, cutting fast-charge time from 18 minutes to 15 minutes.
