The Founding Vision
Origins at MIT
A123 Systems was founded in 2001 at the Massachusetts Institute of Technology (MIT). The company's three co-founders brought together diverse expertise that would prove instrumental in its success: Yet-Ming Chiang, a Chinese-American professor of materials science and engineering at MIT; Bart Riley, a materials science PhD from Cornell University responsible for technology development; and Ric Fulop, a business research consultant at MIT.
In its earliest days, A123 Systems operated with just 5 employees. The company's initial resources were extremely limited: only $100,000 in funding from a U.S. Department of Energy research project and a mere 0.5 grams of material sample taken from MIT laboratories. This small sample, however, contained the seed of revolutionary battery technology that would eventually lead to breakthroughs like the high-performance 3v lithium battery.
The founding team recognized the immense potential of lithium iron phosphate chemistry for next-generation batteries. They envisioned a battery that could deliver higher power, greater safety, and longer cycle life than existing technologies – a vision that would eventually materialize in products like the 3v lithium battery that would find applications across numerous industries.

Early Growth & Development
2004 - Initial Production
In early 2004, with assistance from Taiwan's TECO Electric & Machinery, A123 Systems achieved a significant milestone: the ability to produce 1kg of powder material and one prototype battery per month. This modest production capability represented a crucial step from laboratory research to practical manufacturing.
This achievement proved pivotal in attracting investment, as it demonstrated the technology's commercial potential. The prototype batteries showed promising performance characteristics that would later be refined into the company's first commercial products, including an early version of the 3v lithium battery that would become a staple in many applications.
2004 - First Major Funding
The production breakthrough in 2004 enabled A123 Systems to successfully secure $20 million in initial capital funding. This injection of capital marked the company's transition from a research-focused startup to a commercial enterprise with the resources to scale up development and production.
2006-2007 - Rapid Expansion
By early 2007, A123 Systems had experienced remarkable growth. The company's capital had surged to $102 million, and its workforce expanded to over 250 employees. Orders from companies ranked among the Fortune 500 exceeded $100 million, validating the commercial appeal of their technology.
During this period, A123 Systems began mass-producing millions of battery cells and hundreds of tons of cathode material powder annually. The company's product lineup expanded to include various battery solutions, with the 3v lithium battery emerging as a popular choice for applications requiring reliable, compact power sources.
2007-2008 - Production Scaling
From 2007 to 2008, A123 Systems achieved dramatic production growth, increasing its monthly output from 500,000 cells to 2,000,000 cells. This expansion was driven by growing demand for high-performance battery solutions across multiple industries.
The company's manufacturing capabilities now included large-scale production of the 3v lithium battery, which had become a cornerstone product due to its exceptional performance characteristics and versatility across applications.
Core Technological Advantages
Revolutionizing battery performance through nanotechnology innovations
Nanoscale Material Innovation
A123 Systems' core competitive advantage lay in its ability to manufacture lithium iron phosphate cathode materials for lithium-ion batteries as uniform nanoscale ultra-small particles. This breakthrough dramatically increased the total surface area of the particles, resulting in significantly improved battery discharge power.
Importantly, this enhancement in power output was achieved without compromising overall stability or cycle life – a critical achievement that set A123's technology apart from competitors. This innovation became the foundation for many of the company's products, including the high-performance 3v lithium battery that offered exceptional power density in a compact form factor.
Conventional lithium-ion battery cathode material powders at the time were approximately 100 times larger than those produced by A123 Systems. When other manufacturers attempted to create smaller particles, they faced unavoidable trade-offs in stability and safety, resulting in inherent limitations in discharge power that the 3v lithium battery and other A123 products successfully overcame.
Higher Power Output
The nanoscale particle structure enables significantly higher discharge rates, making A123 batteries, including the 3v lithium battery, ideal for applications requiring bursts of power.
Enhanced Safety
Unlike competitors' smaller particle alternatives, A123's technology maintains superior stability and safety characteristics, even in the high-performance 3v lithium battery designs.
Longer Cycle Life
The unique material structure ensures exceptional durability over thousands of charge-discharge cycles, extending the useful life of products utilizing the 3v lithium battery and other A123 technologies.
