Silatronix sold as battery material race hots up
Battery materials startup Silatronix has been bought by Koura, a US maker of fluorine-based chemicals and technologies for a wide range of industries.

Silatronix was established in 2007 as a high-tech incubator for battery technology by Dr. Robert West and Dr. Robert Hamers, both of the University of Wisconsin-Madison. It was supported by the US Department of Energy and the Office of Naval Research and has been developing new electrolyte technologies for lithium-ion batteries.

Koura is part of the Boston-based Orbia group, which supplies Precision Agriculture, Data Communications, Building and Infrastructure, Fluorinated Solutions and Polymer Solutions sectors. It works with key industry players and researchers in the lithium-ion battery industry to develop and manufacture a wide range of advanced fluorine materials including electrolyte salts, binders and high-performance electrolyte additives. Silatronix brings unique expertise in fluorosilane additives for lithium-ion batteries in a range of applications, from electric vehicles to stationary, grid-scale storage.

Koura and Orbia recently led a $70m investment round in Battery Resourcers, a closed-loop lithium-ion battery recycler based in Worcester, Massachusetts.  Koura is engaged in several initiatives with Battery Resourcers to develop recycling technologies, which the Silatronix team will also support. 

“Alongside our unique ownership of raw material assets and expertise in fluorine technology, Koura is committed to developing next- generation battery technologies that can deliver improved safety, performance and sustainability” said Gregg Smith, President of Koura, which has operations in the UK, Mexico, United States, India and Japan. “Bringing on board Silatronix’s expertise and technologies will further enable us to achieve these goals, support the advancement of the entire lithium-ion battery industry, and accelerate renewable adoption.” 

“Koura’s acquisition of Silatronix is a key step in delivering our advanced electrolyte solutions to the lithium-ion battery markets,” said Mark Zager, CEO of Silatronix. “We are excited to continue building on our strong foundation while supporting Koura’s growth in offering downstream battery products from their material assets.”

“Silatronix’s electrolyte technology and battery expertise complements Koura’s
