New SVP at NanoGraf to lead development of its silicon material for lithium-ion batteries

Lithium-ion battery material company NanoGraf has appointed Doctor In Kim as senior vice-president of its silicon anode technology development.

Dr. Kim will oversee the research and development arm of NanoGraf and lead the company’s team of scientists, technologists and engineers.

Dr. Kim said: “I’m excited to join a team disrupting and redefining silicon-anode battery technology as NanoGraf continues to enable and accelerate main-stream adoption of cleaner, higher performing, and more sustainable lithium-ion batteries.”

Prior to joining the NanoGraf team, Dr. Kim served as vice president of Samsung SDI in 2020, and served as vice president of Samsung SDI Korea for the Next Generation Battery Innovation Group.

In 2020, the U.S. Department of Defense awarded NanoGraf a $1.65 million grant to develop longer-lasting lithium-ion batteries to power US military equipment.

In 2019, the U.S. Advanced Battery Consortium awarded the company $7.5 million to advance EV battery research and development.

Enevate unveils lithium-ion silicon anode that gives fast charging EV batteries 400km driving range

A US firm is claiming to have developed a lithium-ion silicon anode that will give electric vehicles 30% more range in a single charge.

California-based Enevate has designed a porous silicon anodes that it says can hold more lithium ions and move them around faster and at lower cost than traditional anode materials.

Talga and Leclanché sign MoU to trial graphene silicon lithium-ion battery anodes

Switzerland energy storage firm Leclanché will evaluate Australian firm Talga Resources’ range of graphene silicon anode products with the intention of developing commercial products for the lithium-ion battery industry.

The move follows the signing a memorandum of understanding that includes trials to run over a 2-6 month period, and indicative pricing for various volumes of Talnode supply, during the trials and over a three year period.

Firms renew silicon anode strategic partnership for lithium-ion batteries

Chemicals firm Wacker Chemie has upped its interest in the silicon anode market with the purchase of a 25% stake in UK firm Nexeon.

The German firm has also invested an undisclosed sum into the Oxfordshire company that develops and supplies battery materials for rechargeable lithium-ion batteries.

BioSolar plans next steps for silicon in emerging battery tech

US lithium technology firm BioSolar has set out the next steps towards incorporating its silicon additive technology into commercial-grade lithium-ion battery prototypes.

CEO Dr David Lee said: “We anticipate that the next generation lithium-ion batteries are going to require next generation silicon anode materials that provide higher energy and power density.”

Lee told BEST Battery Briefing larger quantities of silicon anode materials incorporating BioSolar's additives are being prepared by the company's partners in South Korea and the US— using BioSolar's proprietary additives and processes and raw silicon materials from Silicio Ferrosolar, a subsidiary of UK-based Ferroglobe.
