Key Highlights: Cutting-Edge Innovations
This year, leading battery companies showcased their latest technologies and products:
-
LG Energy Solution: Unveiled its 46mm cylindrical battery lineup, including the 4680 model inspired by Tesla's 2020 announcement. The battery's energy capacity is reported to be over five times higher than conventional 21mm cylindrical cells. LG also showcased 95mm and 120mm-length batteries, emphasizing customizable design options. Their B-Lifecare battery management service won an innovation award.
-
Samsung SDI: Displayed a high-output 50A cylindrical battery cell with advanced electrode technology, featuring a multi-tab design to enhance both power output and lifespan. They also introduced the SBB 1.5, an enhanced energy storage system (ESS) that had previously won an innovation award at the 2024 exhibition. Additionally, Samsung SDI collaborated with robotics and autonomous vehicle companies, such as A2Z's Level 4 self-driving bus ROii.
-
SK On: Showcased its comprehensive battery portfolio, including pouch, prismatic, and cylindrical cells. Notably, the company introduced an immersion cooling technology developed in collaboration with SK Enmove, designed to improve EV battery thermal management. They also highlighted their wireless battery management system (BMS), which optimizes space efficiency and cooling performance.
Chinese Companies Entering the Scene
For the first time, major Chinese battery manufacturers, including BYD and EVE Energy, participated in InterBattery. BYD exhibited its cylindrical lithium iron phosphate (LFP) battery, attracting steady visitor traffic, although its booth was less crowded than those of Korean firms. This underscores the intensifying competition between Korean and Chinese battery makers, prompting Korean firms to adopt differentiation strategies to maintain a competitive edge.
InterBattery Awards and Industry Recognition
At the InterBattery Awards, LG Energy Solution won two awards for its 46-series cylindrical battery and B-Lifecare service. Samsung SDI also received recognition for its high-output cylindrical battery and advancements in LFP material technology. These accolades highlight the companies' technological leadership and set the direction for future battery innovations.
