UL Solutions offers independent third-party testing and certification across the battery value chain—from raw materials validation and sustainable sourcing, through cell manufacturing (safety, reliability, abuse tolerance), to module and pack assembly (safety, performance, endurance) and end-of-life recycling validation. It supports lithium-ion, nickel cell, and button cell chemistries, performing performance testing (charge/discharge profiles, cycle life, thermal resilience), abuse and safety tests (crush, nail penetration, short circuit, thermal runaway), and ensuring compliance with UL standards (UL 1642, UL 2054, UL 2271) as well as IEC and UN regulations.
In 2025 UL Solutions opened its Advanced Battery Testing Laboratory in Aachen, Germany—replacing a site acquired in 2024—to expand battery testing, simulation, failure analysis, and certification for automotive and stationary energy storage. Also in 2025 it enhanced Battery Energy Storage System safety testing by updating test methods for non-lithium chemistries, such as sodium-ion, in line with ANSI/CAN/UL 9540A fifth edition, improving fire risk mitigation and thermal runaway containment.
UL Solutions went public in 2024 on the New York Stock Exchange (ticker ULS), with Goldman Sachs, J.P. Morgan, and BofA Securities managing the IPO. As of mid-2025, the company has a market capitalization of about $13.2B. In Q2 2025, revenue reached $776M, up 6.3% year-over-year.
