LG Energy Solution, Samsung SDI win InterBattery Awards

By Lee Min-hyung

LG Energy Solution and Samsung SDI have claimed honors at InterBattery Awards 2025, proving their battery tech prowess for the second straight year, the two battery firms said Monday.

The selection was made by the Korea Battery Industry Association ahead of InterBattery 2025, scheduled to take place from March 5 to 7.

LG Energy Solution claimed two awards for its next-generation 46-series cylindrical battery cells and advanced battery management services.

The company’s cylindrical battery, with a diameter of 46 millimeters, earned the achievement for boosting energy output by at least five times compared to its predecessor. The battery is also set to debut at InterBattery.

LG’s B-Lifecare battery management service also won an award. The service helps drivers monitor their EV battery condition in real time, providing an optimal battery management solution to users by analyzing driving and charging patterns.

Last year, the company won two awards for its mid-nickel pure nickel-cobalt-manganese technology and anode laser etching technology, among others.

“We will show our vision and growth potential at the upcoming fair,” an official from LG Energy Solution said.

Samsung SDI, another leading battery maker, won two awards for its 50-ampere high-power cylindrical battery cell and its material and electrode technology for its lithium iron phosphate (LFP) plus platform. These awards highlight the company’s innovative battery technologies. Last year, Samsung SDI's energy storage system received the honor.

“The latest achievement proves our technological capabilities to constantly innovate and challenge,” an official from Samsung SDI said. “We will continue to proactively discover future technologies.”

The 50-ampere high-power cylindrical battery features a design with multiple tabs on the ends of the electrodes, extending its current path and reaching the industry’s highest capacity. When it is applied to power tools, it increases the power by up to 40 percent, compared with batteries of the same capacity.

The battery will be launched in the second quarter of this year. Fast-charging technology enables its 80-percent charge in only 15 minutes, according to the company.

The material and electrode technology for the LFP plus platform is a solution to enhance energy density and cell resistance of LFP batteries. The company developed the technology by blending LFP with high-nickel material to improve energy density by some 10 percent from conventional LFP batteries.
