The Need

As the world rapidly transitions to electric mobility and seeks to combat climate change, the transportation sector faces a pressing challenge. Electric vehicles (EVs) hold the key to a sustainable future, but their high cost, primarily driven by expensive lithium-ion batteries, hinders mass-market adoption. Automakers urgently require breakthroughs in battery technology to significantly reduce costs, increase energy density, and improve cycle life, paving the way for profitable mass-market electric vehicles. To achieve this, a new generation of cathode chemistry is essential, offering higher specific energy, extended life, and reduced reliance on critical materials like cobalt.

The Technology

This technology is a cutting-edge approach of cathode stabilization for high-performance and next-generation cathode materials. Leveraging state-of-the-art solid electric conductors, the technology effectively passivates the cathode surface, extending the lifespan of cathode materials like nickel-rich LiNi1-xMn0.5xCo0.5xO2 (NMC with x ≤ 0.2) and high-voltage LiNi0.5-xMn1.5-yMx+yO4 (M = Ti, V, Cr, Mg, Al, Co, Fe, Cu, Zn) spinel oxide. By addressing the unwanted cathode/electrolyte reaction, it ensures enhanced performance and reliability for electric vehicles.

Commercial Applications
