SAMSUNG SDI has won the 2025 InterBattery Award for its Material and Electrode Technology for LFP+ Platform. SAMSUNG SDI’s LFP+ technology is designed to compensate for the low energy density and limited driving range of conventional LFP materials while enhancing fast-charging capabilities.

SAMSUNG SDI has developed a LFP+ material technology which combines high nickel and LFP, improving energy density by 10% compared to conventional batteries. At the same time, the technology maintains the safety and long lifespan characteristics of LFP batteries. Additionally, by applying anode electrode technology, SAMSUNG SDI reduced the fast-charging time* from 80% in 25 minutes to 80% in just 20 minutes.

*Fast-charging time is the time it takes to charge a battery from 0% to 80%

One of the major limitations of the widespread adoption of EVs has been their short driving range and longer charging times compared to internal combustion engine vehicles. SAMSUNG SDI’s LFP+ material and electrode technology ensures both the high energy density and fast-charging performance, significantly improving user convenience for EV owners.

SAMSUNG SDI has been actively developing various cathode material technologies beyond LFP. The company initially produced lithium-ion batteries using LCO and NCA materials, later advancing to NCM and NCA materials. From the late 2010s, SAMSUNG SDI has been preparing for mass production of high-nickel prismatic batteries which offer greater capacity and enhanced safety. These efforts led to the successful mass production of EV batteries using NCA material with 88% nickel content in 2021 and 91% nickel content in 2024.

To achieve even higher energy density and safety, SAMSUNG SDI is also developing solid-state batteries. The company applied its propriety solid electrolyte materials and an anode-free design, increasing energy density up to 900Wh/L. In March 2022, SAMSUNG SDI became the first in Korea to launch a pilot line, known as the ‘S-Line’, and is targeting commercialization by 2027.

SAMSUNG SDI is continuously advancing its fast-charging technology. The company plans to secure low-resistance materials and optimized electrode structures to implement ultra-fast charging technology by 2026. Once applied, this technology will enable EVs to charge enough electricity for 300km of driving in just 5 minutes. 

SAMSUNG SDI remains committed to delivering high-performance and safe batteries, continuously pushing the boundaries of battery technology.
