Rechargeable batteries are widely used to power electronic devices. Rechargeable batteries are made out of particles of active material; their chemistry, spatial distribution, alignment, and morphology determine its performance. Poor processing of the particle powders that define the power density of existing rechargeable batteries result in battery material that is well below the theoretical ideal of optimal utilization, affecting performance and lifetime. Currently, trial-and-error experiments are performed in attempts to improve battery performance. Existing optimization solutions are expensive and difficult to implement.

Researchers at Purdue University have developed the ideal powder morphological properties of rechargeable battery materials to deliver tailored (optimal) power or energy densities for rechargeable Li-ion batteries. Their particle morphology and microstructure designs can deliver up to six times the energy density or five times the power density compared to existing technologies. The design of the battery microstructures allows for optimal, tailored performance for specific applications, such as, high energy density, high power density, and intermediate range applications that maximize the performance of a specified chemistry.

Advantages:
-Optimal power or energy densities
-Customizable for specific applications
-Improved performance
-Less expensive

Potential Applications:
-Battery manufacturers
