PPG Partners With SiNode Systems for EV Battery Technology Focused On High-Energy Anode Materials

PITTSBURGH — PPG Industries Inc. (NYSE: PPG) today announced it has entered into a partnership with SiNode Systems to accelerate the commercialization of high-energy anode materials for advanced battery applications in electric vehicles.

The 30-month project will enable the partners to rapidly develop and demonstrate anode materials that will store more energy than conventional lithium-ion battery materials, enabling electric vehicles (EVs) to travel farther on a single charge or to have a lighter-weight battery.

Founded in 2012, SiNode Systems is an advanced materials company developing silicon-graphene materials for the next generation of lithium-ion batteries. SiNode materials offer higher battery capacity with faster charging rates.

SiNode Systems is commercializing a patented composite of silicon nano-particles and porous graphene. The material is produced in a sheet-like form through a simple and highly scalable manufacturing process. It's compatible with standard li-ion battery components (cathode and electrolyte), which means it can be used as a direct drop-in component to existing battery cell manufacturing—increasing anode capacity by 10 times, while decreasing battery charging times by the same factor.

In 2016, SiNode was selected among several competitors to receive a contract for the project from the United States Advanced Battery Consortium LLC (USABC), which is providing 50 percent of the project's funding through the U.S. Department of Energy. Project partners are funding the remaining 50 percent.

The project will focus on improving the stability and scalability of SiNode's anode materials to meet or exceed USABC targets for a battery's active materials, which store the energy. Raymor Industries will provide graphene – a nanoscale-thin layer of pure carbon that is required for the high-energy anode materials – to PPG, which will then prepare the material for SiNode. PPG will help both Raymor and SiNode scale up their manufacturing processes to production volumes to support the project.

"Partnering with PPG will allow us to accelerate the commercialization of our battery materials platform for a wide range of markets, from consumer electronics to electric vehicles," said Samir Mayekar, SiNode co-founder and CEO. "Our team is thrilled to collaborate with PPG."

Kurt Olson, PPG research fellow, said, "We believe SiNode's technology has great potential to benefit the battery market, and we appreciate this opportunity for collaboration. Boosting the range and reducing the weight of electric vehicles through batteries that store more energy will increase the practicality of, and consumer interest in, these cars. Applying PPG technology to help improve the sustainability of products, such as electric vehicles, is a strategic goal for us, and we are pleased to participate in this project."

PPG's current goal is to have 40 percent of its total sales derived from sustainable products by 2020. The company met its initial 30 percent goal five years ahead of schedule in 2015.

SiNode seeks to change the landscape for lithium-ion batteries so they can meet the demands of a wide range of industries, from consumer electronics to electric vehicles.

In 2016, Ford, General Motors and Fiat Chrysler, along with the U.S. Department of Energy, awarded a $4 million contract to SiNode Systems to help the startup develop its technology for the electric vehicle market.
