Battery-makers are eagerly researching ways to incorporate silicon, which can potentially store 10 times as much energy as graphite, into anodes. Now silicon anode specialist GDI says it has developed a 100% silicon roll-to-roll processed anode for next-generation batteries, potentially enabling graphite-free battery cells that deliver far higher energy density, faster charging and greater safety… Read more »

Panasonic to use Sila’s Titan Silicon anode material, which promises higher energy density for EV batteries
Panasonic and battery materials company Sila Nanotechnologies have signed a commercial agreement for Sila’s nano-composite silicon anode, Titan Silicon, which could enable the battery maker to dramatically improve both vehicle range and charging time. Sila’s anode materials, to be produced at the company’s plant in Moses Lake, Washington, will be optimized for Panasonic’s next-generation lithium-ion… Read more »
Nexeon secures site and raw material supply for silicon anode material plant
Battery material manufacturer Nexeon has obtained property near to chemical company OCI’s facilities in Gunsan, South Korea for its first commercial-scale silicon anode material plant. Nexeon has also struck an agreement with OCI for a long-term supply of monosilane, a by-product gas from the Gunsan plant’s semiconductor polysilicon production and a crucial raw chemical for… Read more »
Group14 begins construction of second US silicon battery materials factory
Battery manufacturer Group14 Technologies has begun the construction of its second commercial-scale Battery Active Materials (BAM-2) factory in Moses Lake, Washington. The 1 million-square-foot campus will manufacture commercial quantities of SCC55, together with the BAM-1 factory in Woodinville, Washington. SCC55 is a stable silicon-carbon composite anode with five times the capacity of graphite, which affords… Read more »
NanoGraf raises $65 million in Series B financing to scale production of silicon anode products
Battery materials company NanoGraf has raised $65 million in a Series B funding round that was co-led by Volta Energy Technologies and CC Industries. NanoGraf had previously raised a total of $27 million from a mix of funding sources. NanoGraf’s technology enables battery-makers to incorporate more silicon into their anodes. Current EV battery anodes are… Read more »
How NanoGraf is commercializing the “world’s most energy-dense” 18650 battery cell with stable silicon oxide
Q&A with NanoGraf COO Connor Hund Graphite, a pure form of carbon, is a critical material for battery anodes. Graphite’s physical structure allows it to store lithium ions, which merrily migrate to the anode when the battery is charged. Unlike cathodes, which can be composed of various combinations of chemicals (cobalt, nickel, manganese, lithium, iron,… Read more »
Ingevity invests $60 million in silicon anode specialist Nexeon
Chemical and materials company Ingevity has invested $60 million in silicon anode specialist Nexeon. “Ingevity’s funding will enable Nexeon to further develop its proprietary next-generation silicon anode material, NSP-2, and facilitate the construction of manufacturing facilities for the commercialization of Nexeon’s innovative products,” says Ingevity. “With an astounding four times the energy density per gram… Read more »
Group14 raises $400 million for silicon-carbon battery materials factory in US
Silicon-carbon battery tech supplier Group14 Technologies has raised $400 million in Series C funding, which it plans to use to open its second battery active materials factory in the US. The plant will produce the company’s proprietary SCC55 lithium-silicon battery material for Porsche subsidiary Cellforce Group, which will use it to begin producing battery cells… Read more »
HPQ Silicon: a project for the development of silicon-based anode materials
HPQ Silicon has announced that HPQ, PyroGenesis Canada and the Énergie Matériaux Télécommunications Centre (ETM) of the Institut national de recherche scientifique (INRS) have set up a research project focused on the development of silicon-based materials as active anodes for lithium-ion batteries. HPQ and PyroGenesis will be responsible for the production of silicon materials from… Read more »
Silicon anode nanostructure could increase battery capacity and lifespan
Image caption: In the first stage, the silicon film exists as a rigid but wobbly columnar structure. In the second stage, the columns touch at the top, forming a vaulted structure, which is strong due to arch action. In the third stage, further deposition of silicon atoms results in a sponge-like structure. The red dashed… Read more »
