Latest Patents

Jeong’s listed patents address the structure and preparation of positive electrode active materials for secondary batteries.

One patent describes a precursor made of aggregated primary particles, with a nickel, cobalt, and manganese core surrounded by a shell that also contains aluminum. The primary particles in both regions are rod-shaped, and those in the shell have a smaller average major-axis length than those in the core. The disclosure also covers preparation methods and a positive electrode active material made from the precursor.

The other patent concerns a precursor whose primary particles are oriented from the center of each secondary particle toward its surface. The particles contain crystallines with a (001) plane arranged at an angle of 20° to 160° relative to the primary particle’s major axis. The patent also describes a method for preparing the precursor.
