Column: Trump 2.0 won’t reverse Biden’s critical minerals push
Donald Trump has described the Inflation Reduction Act (IRA) as a "green scam" and vowed to repeal it after he returns to the White House in January.
Nano One Materials (TSX-V: NNO) announced that its high-performance lithium-ion battery cathode materials, which are produced at a low cost using proprietary technology, tested positively in solid-state batteries for electric vehicles.
The largest single challenge for those working on solid-state batteries is being able to design a stable and commercially viable interface between the solid electrolyte and the solid cathode and anode materials on either side of this electrolyte
In a press release, the company said that it is working with various automotive manufacturers to evaluate its One-Pot process and coated lithium nickel manganese oxide cathode materials (LNMO).
According to Nano One, the coated LNMO, also referred to as high voltage spinel, stabilizes the interface between cathode and electrolyte because it does not expand and stress the cathode-electrolyte interface like other cathode materials, and also because the coating protects the cathode from side-reactions with the electrolyte while allowing the rapid transfer of lithium ions between the electrolyte and the cathode.
“In comparison to other cathode materials, HVS is faster charging and operates at higher voltage enabling increased power and energy densities,” the Canadian firm said in the media brief. “HVS is also free of cobalt and the associated supply chain risk.”
In the view of Stephen Campbell, CTO of Nano One Materials, the main goal behind all the research on solid-state batteries is to replace flammable liquid electrolytes with solid materials that improve safety, power and energy density of batteries.
