An “Ideal” Battery That Looks Like a Sandwich

Sandwich structures are common in aircraft, combining high stiffness, light weight, and structural strength.  Could such a structure be useful in enhancing energy storage?  Pennsylvania State University researchers think they’ve answered that question in a positive way. Sandwich-like Structures as Energy Storage Materials The blog has examined the possibilities inherent in incorporating batteries and supercapacitors into structures, but making the battery itself a sandwich structure could leave it as a discrete component within an electric vehicle, or lead to its being adapted as a full structural element.   Penn State University materials scientists have achieved the goal of making a “polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use.”  Their …

While much of battery research goes into crafting the ultimate anode, cathode or electrolyte, there seem to be few efforts, at least to outside observers, of integrated approaches to making a better total battery.  That may change soon, with the Department of Energy announcing formation of a new Joint Center for Energy Storage Research (J-CESR, or J-Caesar).   Dr. Steven Chu, U. S. Secretary of Energy, has established the Center at Argonne National Laboratory with a budget of $120 million over five years to create a battery five times more powerful and five times cheaper than today’s norms – all within five years. For those of us who’ve grown wary of those “breakthough” announcements that almost always include the line, …
