High Energy and Power Density Batteries
Lithium ion batteries have been realized for their high energy densities [1]. However, low electronic conduction and slow ion transport are some of the issues that limit a battery’s charge/discharge rates. Our bicontinuous electrode structures provide quicker pathways for both ions and electrons (Figure 1). My research focuses on developing electrochemically-active materials and incorporating them into innovative 3D electrode architectures. By these efforts, we can expect to obtain significant improvements in batteries’ electrical and mechanical performance.
