With more than two decades of continuous innovation in materials science, manufacturing, and intelligent control systems, A123 delivers the performance, safety, and reliability demanded by modern mobility and energy applications. Backed by over 903 authorized patents and 645 original inventions, A123 continues to pioneer next-generation lithium-ion technologies that power cleaner, smarter, and more sustainable solutions worldwide.
Our company is a worldwide leader in battery technology
A123 Systems holds a global patent for its advanced Super-Nano Lithium Iron Phosphate (LFP) technology, recognized worldwide for its exceptional safety, high power density, and long cycle life. This proprietary chemistry forms the foundation of our 12 V start-stop and 48 V low-voltage battery systems, which together command nearly half of the global market share, reflecting our continued leadership in the segment. In parallel, A123’s proprietary NMC ternary material technology—celebrated for its outstanding safety performance—has earned us a position as a designated supplier for one of the world’s largest OEM electric-vehicle platforms (MEB).
This is something I noticed in general: Missing spaces between number and capacity, be it 12V vs 12 V, 587Ah vs 587 Ah etc - this is still inconsistent throughout the website and should be adapted.
Our global R&D organization includes more than 1,000 research and engineering professionals with an average of over 15 years of experience, driving ongoing breakthroughs supported by more than USD 700 million in cumulative investment. A123’s technology portfolio spans lithium iron phosphate, NMC ternary, and solid-state chemistries, engineered to meet a full spectrum of performance requirements—from ultra-high power and high specific energy to balanced, long-life solutions. Our products power 12 V and 48 V low-voltage systems, high-voltage batteries for BEVs and PHEVs, Formula 1 racing applications, and large-scale energy storage systems, delivering the performance, safety, and reliability trusted by global customers.
