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.

Nexeon wins EV battery research funding

UK-based battery materials firm Nexeon has been awarded GBP7million ($9.5m) to support research into silicon-based materials to increase the safety and range of batteries for electric vehicles.

Nexeon said the support from the government’s Innovate UK agency will support its work with partners on a project called ‘SUNRISE’ to develop improved materials, based on silicon as a replacement for carbon in the lithium-ion battery anode and optimising cell designs for automotive application.

Semi-conductor material key to maximising lithium batteries

Extremely thin layers of silicon may hold the key to unlocking up to six times more capacity in lithium-ion batteries.

Silicon can help the battery’s anode reach its maximum load of lithium, claim scientists from Helmholtz-Zentrum Berlin (HZB) Institute of Soft Matter and Functional Materials.
