The opening of "INTERBATTERY 2025," the largest battery industry exhibition in Korea, is just ten days away. Major battery companies will unveil next-generation innovative technologies and new products to target the market. As the electric vehicle market advances, the demand for battery performance and efficiency is increasing, making it a focal point to see what strategies and technological competitiveness each company will present.

According to the industry on the 23rd, about 640 companies, including the three major battery companies (LG Energy Solution, Samsung SDI, SK On), along with secondary battery manufacturers and companies related to materials, parts, and equipment, will participate in "INTERBATTERY 2025," which will be held at COEX in Gangnam, Seoul, from March 5 to 7, hosted by the Ministry of Trade, Industry, and Energy.

LG Energy Solution will publicly unveil its next-generation cylindrical battery, the 46-series cell lineup, for the first time. A solar mobility vehicle from the U.S. solar electric vehicle startup "Aptera Motors," which will be powered by LG Energy Solution's batteries, will also be displayed.

The company will also showcase differentiated technologies related to BMTS (Battery Management Total Solution). LG Energy Solution's BMTS is an advanced solution that monitors battery data to ensure optimal performance, integrating cloud and AI technologies to provide enhanced safety diagnostics, degradation, and lifespan predictions. Additionally, the company will present LFP-CTP (Cell-to-Pack) technology, which improves cost competitiveness while maintaining high safety, as well as high-voltage mid-nickel (Mid-Ni) pouch cells, which reduce nickel content and increase energy density through high voltage.

An LG Energy Solution representative stated, "This exhibition will showcase LG Energy Solution's vision and growth potential, demonstrating that the company is not just focused on battery manufacturing, but also positioning itself at the heart of the entire 'energy circulation' ecosystem to open up endless business opportunities."

Samsung SDI will showcase a variety of next-generation battery products and innovative technologies under the slogan, "Upgrading Our Daily Life with Battery Technology, InCelligent Life."

Samsung SDI plans to highlight the differentiated safety of its prismatic batteries by presenting technologies such as the "No TP" (No Thermal Propagation) technology, which has recently completed commercialization review, as well as solid-state batteries (ASB) and Cell-to-Pack (CTP) products. The company aims to focus on promoting the superior safety features of its products.

No TP is a technology that physically prevents heat from propagating to other cells when an issue occurs in a specific cell of a battery product, using safety materials applied between the cells. By utilizing an independent thermal propagation prediction program (TPc), optimal structural designs for heat propagation prevention can be achieved from the product planning stage.

Samsung SDI will also introduce the development status of its solid-state batteries. Solid-state batteries use a solid electrolyte, which reduces the risk of fire and offers longer driving ranges, earning them the nickname "dream battery" in the industry.

Samsung SDI explained that after supplying samples to several customers at the end of last year for evaluation, the company is now preparing the next stage of samples and is progressing smoothly toward commercialization, with a goal of launching solid-state batteries by 2027.

A Samsung SDI representative stated, "We have continuously strived for qualitative growth based on differentiated technology and quality." They added, "Through this exhibition, visitors will be able to witness how our daily lives are being upgraded by battery technology and the technological competitiveness that makes it possible."

SK On will showcase all three major form factors (pouch, prismatic, and cylindrical) to emphasize its readiness to meet the diverse needs of the market.

Notably, SK On will publicly unveil a cylindrical battery prototype for the first time and introduce its strategy and direction for cylindrical battery development. In the second half of last year, SK On completed the construction of its cylindrical pilot line and has been accelerating research and development efforts.

In addition to the bidirectional model, SK On will showcase a unidirectional model of prismatic batteries at this year's exhibition. The company will also introduce Z-folding stacking technology and a fast-charging solution applied to its prismatic batteries.

In line with market trends, SK On will present several products featuring different chemistries for cathode and anode materials. The company will unveil its high-voltage mid-nickel battery for the first time at this exhibition, highlighting its price competitiveness, performance, lifespan, and safety.

SK On will also showcase a next-generation wireless Battery Management System (BMS) that eliminates the need for wiring. The system works by using wireless chips attached to the battery cell tabs to collect data, which is then transmitted wirelessly to the BMS through the module's antenna.

A representative from SK On stated, "SK On will continue to strengthen its research and development capabilities and build a portfolio that meets customer demands, securing a differentiated competitive advantage."
