XG SiG™ Li-ion Battery Anode Materials

XG SiG™ is a composite of silicon and graphene nanoplatelets designed to deliver 3-5 times the energy storage capacity of today’s graphite-based LiB anodes. Anode capacity is a key driver for extended battery runtime in applications such as portable electronics, power tools and electric vehicles (“EV”). Silicon has 10x the storage capacity of graphite and has been targeted as the next-generation material to replace graphite. However, silicon suffers from poor cyclability limiting its adoption in LiB anodes. XGS’ breakthrough is the creation of a SiG composite that allows the use of silicon as an active component in anodes, delivering on the industry need for long battery cycle life, high efficiency and at a cost and scale that meets industry targets. Product design-in is underway with battery manufacturers targeting early commercialization performance requirements. The combination of performance, cost and manufacturability positions XG SiG™ and XGS as a leader in high energy density LiB materials.

Strategic Investors, License Agreements and Financing

XGS has partnered with leading global companies as manufacturing, technology and distribution partners as a way to accelerate XGS’ customer and manufacturing reach. Each of these partners has spent significant time with XGS to validate the technology and market need.

XG SiG™, Silicon Graphene Lithium Ion Battery Anode Replacement

XGS has developed an advanced silicon-based anode material that, as a critical battery component, can potentially enable cells with high energy density for future generation batteries, enabling longer battery life and/or more functional performance for portable electronics. Silicon (Si) is considered the most promising anode material due to its high charge storage capacity and proper working voltage. Theoretically, Si can provide up to 4,200 mAh/g of Lithium storage capacity, which is more than 10 times that of graphite. It can be lithiated in the potential range of 0.0 ~ 0.4 V, which enables a high energy density battery when paired with an appropriate cathode. The global market for lithium ion anode materials is estimated to be $1.3 Billion in 2018, according to Avicenne Energy, "The Worldwide Rechargeable Battery Market 2014 - 2025", 24th Edition - V3, July 2015 & Internal Estimates.

Two major barriers have hindered the development of Si-based anodes for commercial applications, especially for use in EV batteries: poor cycle life and high synthesis costs. XGS’ Si/graphene (SiG) composite anode is based on a unique nano-structure design and an innovative compositing process that utilizes graphene to mitigate stability issues of Si particles during cycling. Graphene creation and SiG compositing is achieved in a single unit process using an existing manufacturing process and low cost industrial precursors. Unlike other Si/graphene based materials where graphene is often produced separately and Si is deposited onto the graphene using exotic methods, XGS’ one-pot process allows the production of SiG material at high volume and low cost.

XGS SiG material technology is considered as a leading candidate for next generation anode materials. XGS received a $1.2MM grant from the DOE to further develop this technology. Samsung Ventures invested in XGS and we entered into a joint development program with Samsung SDI, the world’s leading lithium ion battery manufacturer. XGS developed its technology to a level that allows it to aggressively pursue commercial efforts in applications requiring high energy storage and with cycle life up to 250 cycles. XGS is pursuing commercialization in those applications. In parallel, XGS has formed, and is seeking additional development relationships that will advance its technology, making it more amenable to a broad industry adoption. XGS announced in December, 2015 a joint development relationship with Boston Power. In April 2016, XGS was granted an award from the DOE’s Small Business Vouchers program and will jointly work with Lawrence Berkley National Laboratory to meet extended life-time requirements for high-energy-density lithium ion batteries. In May 2016, XGS was selected for a Phase I SBIR grant in support of the Electric Drive Vehicle Batteries program to establish low-cost manufacturing of functionalized Silicon-graphene composite anode for reduced SEI formation. In October 2016, XGS was selected by a major European automaker to produce SiG-based cells for use in confirming safety attributes of silicon in Li-ion batteries. In November 2016, XGS granted a European cell manufacturer permission to sell batteries commercially containing XGS’ SiG composite anode material. In March 2017 XGS completed the DOE-funded Phase I SBIR development project demonstrating feasibility of three potential materials improvements: 1) Optimization of the graphene/Si ratio and manufacturing process, 2) Identification of commercially available Si precursor that improves volumetric expansion with no detriment to performance, and 3) Capability to augment anode material performance through functionalization. In April 2017 XGS teamed with cell manufacturer Farasis Energy to submit a proposal for a $1MM, 24-month Phase II SBIR development program to DOE. LG Chem, Ford, Daimler, Boston-Power, and A123 Systems all provided letters supporting XGS’ SiG material approach and agreeing to material evaluation. Award decisions are expected in early summer. XGS is currently in active discussions with other parties to form additional joint development arrangements targeting both technology development and specific commercial implementation.
