High Energy Density, Cobalt-Free Lithium-Ion Battery Developed
ALTERNATIVE POWER REPORT
Guy Youngs Today’s electric vehicles are predominantly powered by nickel-manganese-cobalt (NMC) lithium-ion batteries. However, the inclusion of cobalt in this type of batteries has been considered problematic due to its anticipated scarcity as well as the associated supply chain risks related to its single source, human rights and mining practices.
Japanese scientists have developed a high energy density, cobalt-free lithium-ion battery that yields about 60% greater energy density than conventional lithium-ion batteries for an equivalent weight and volume and sustains unprecedented 1,000 cycles.

China Discovers Unique Battery Material
Guy Youngs A newly discovered ore containing vast quantities of an element widely used in semiconductors has been found in China. The discovery could propel new advances in battery technology.
Geologists have found the rare earth metal niobium inside the new ore named niobobaotite from north China’s Inner Mongolia. The rare earth metal is widely used in alloys for jet engines and rockets and has also been shown to have exceptional current conducting properties in low temperatures.
Researchers have said batteries made from niobium have several advantages over traditional lithium-ion batteries. The Brazilian Metallurgy and Mining Company (CBMM) has been working on new projects towards the use of niobium to make advanced lithium-ion batteries.

Toyota Joins Race To Mass Produce Batteries
Toyota Motor Company is the latest automaker delving into solid-state battery technology, vowing to mass produce the safer and more energy dense cells in four years.
The Japanese automaker has recently changed its tune about building BEVs and is now claiming solid state batteries will be in vehicles starting in 2027.

Could Toyota’s Ammonia Engine Bring the End of EVs?
The technology is the result of a collaboration of Toyota with the GAC Group, a Chinese state-owned manufacturer. The ammonia engine is a form of internal combustion engine (ICE) powered primarily by ammonia, (ammonia is comprised of a nitrogen atom and three hydrogen atoms). It does not contain carbon. As a result, when it’s burned in an ICE, it does not release carbon dioxide, one of the major greenhouse gases. In the effort to decarbonize, the potential of this type of technology is considerable.
