Molyon

Molyon is a Cambridge University spinout on a mission to commercialise the next generation of lithium-sulfur (Li-S) batteries. Founded in February 2024 by Dr. Ismail Sami, Dr. Zhuangnan Li, and Professor Manish Chhowalla, the company emerged from 15 years of materials science research in Cambridge's Chhowalla Group. It is tackling a fundamental limitation of current energy storage technology: lithium-ion batteries are hitting a performance ceiling just as global demand for high-energy, lightweight power sources is accelerating across electric vehicles, drones, robotics, and aerospace.

Molyon's breakthrough lies in using metallic molybdenum disulfide (MoS2) as a cathode additive in Li-S batteries. This patented approach solves the core problem that has prevented Li-S commercialisation for decades — the dissolution of sulfur into the electrolyte, which causes rapid battery degradation. With MoS2 stabilising the cathode, Molyon's batteries can achieve energy densities of 500 Wh/kg over hundreds of cycles: approximately twice that of standard lithium-ion. The technology uses earth-abundant materials including sulfur and molybdenum, reducing dependence on critical minerals such as cobalt, nickel, and graphite.

In November 2024, Molyon closed its first funding round of $4.6 million, co-led by IQ Capital and Plural, to begin manufacturing at its pilot facility in Cambridge. The company's near-term focus is on drones and robotics, where the weight advantage of Li-S batteries is most immediately transformative, before scaling to electric vehicles and energy storage — a global battery market estimated at over $85 billion.
