The High Voltage Cathode

Mastering Lattice Stability and Doping Beyond 4.5 Volts

The future of energy density lies in the stability of the crystal lattice.

Strategic Objectives

• Master the crystallography of high-delithiation states to prevent material degradation.

• Implement advanced doping strategies to stabilize transition metal layers.

• Understand the mechanics of oxygen evolution to enhance battery safety.

• Explore the frontier of high-voltage cathode materials for next-generation EVs.

The Core Challenge

Pushing lithium-ion batteries above 4.5V often leads to catastrophic structural collapse and hazardous oxygen evolution.
