Pilot plant pushes NEO closer to lithium-ion silicon anode material commercialisation

Canadian lithium-ion battery material firm NEO Battery Materials is on the verge of developing a first prototype of its silicon anode material.

NEO is in the scale-up phase of commercialisation following the successful integration of its silicon (Si) technology in commercial graphite anodes.

In phase one, NEO will provide graphite/Si mixture anode materials with different levels of Si content for controllable anode specific capacity. 

NEO reports it has achieved ~500 mAh/g, at a 70% capacity enhancement.

Spencer Huh, president and CEO of NEO, said: “The development of our prototype is part of our research to increase the specific capacity of our high silicon content anodes with graphite, and we are also onto a new strategic move into integrating NEO’s silicon with solid-state electrolytes. 

“We are in discussion with parties in the industry to explore and discover potential synergies and mutual benefit for NEO’s silicon anode technology.”

The firm has also announced the initiation of a pilot plant project where it intends to use in-house resources to design and test equipment that will use its single-step Si nanocoating process.

Sung Rock Hwang, chief operating officer and senior vice president of NEO, said the goal of the project was to establish a basic pilot-scale coating process design and to check the feasibility of NEO’s nanocoating technology for metallurgical-grade silicon.

He added: “Moreover, we are further focusing on a cost-effective separation method since it will capture the largest portion of energy consumption during our nanocoating pilot process. 

“The pilot plant project aims to prove the capacity of the Company to produce various sized Si materials ranging from ~50 nanometers to several micron-sized Si materials that are strategically important to conventional liquid-based Li-ion batteries and next generation all-solid-state batteries (ASSBs).”

The company’s directors, scientific advisors, and engineers are in the process of working on the conceptual design of the pilot plant, which marks the first step towards realising wide-scale production.

18650 lithium-ion cell breakthrough announced by Nanograf

18650 lithium-ion cell breakthrough announced by Nanograf

Advanced battery material company NanoGraf has developed a breakthrough silicon-anode based lithium-ion 18650 cylindrical cell.

The company claims its 3.8 Ah, 18650 cell can achieve 800 watt-hour per litre (Wh/L) and provides a 28% longer run time than traditional cell chemistries— although the cycle life was not disclosed. 

NanoGraf’s team of scientists, technologists, and engineers unveiled the cell they say could benefit any application from consumer electronics to electric vehicles thanks to funding from the U.S. Department of Defense.

NanoGraf president, Dr. Kurt Breitenkamp, said: “This is a breakthrough for the battery industry. Energy density has plateaued, only increasing eight percent or so over the last decade. 

“We just achieved a 10 percent increase in a little under a year. This is over a decade’s worth of innovation in one technology.” 

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

The funding required NanoGraf to develop a battery cell that can operate across a temperature range from -4°F to 131°F, and has a shelf life of more than two years.

In 2019, NanoGraf, formerly SiNode Systems, was awarded a $7.5 million grant to develop its graphite anode replacement product ahead of commercialisation plans.

The funding from the United States Advanced Battery Consortium (USABC), a subsidiary of the United States Council for Automotive Research, was awarded for a 36-month project.

American manganese reports promising lithium-ion battery recycling results

Tue, 10/29/2019 - 15:07 -- paul Crompton

Recycled materials firm American Manganese has received positive results from third-party testing of its RecycLiCo™ lithium-ion battery material recycling just weeks after completing the fifth and final stage of tests at its pilot plant.

The company has released the results from its independent contract laboratory, Kemetco Research regarding test by a tier-one firm— referred to as Company A due to a confidentiality agreement.
