BATTERY POWER


POWER SOLUTIONS FOR THE SOLDIER


Developments in battery research could change how much batteries weigh, how long they last, and how much power they provide. Here, a member of a Coalition and Afghan Security Force uses battery-powered night vision devices and a weapon-mounted aiming light to detain suspected insurgents July 9 in Kandahar province, Afghanistan.

We are researching fuel cells, solid-state capacitors for pulse power. In addition,     do we get hydrogen from a logistics fuel like JP8? Chemicals have the highest  energy in a chemical such as hydrogen or JP8, but it needs to be in a form that can be used. Fuel cells can use only hydrogen. To use JP8 as a fuel, we have to convert it.


We have a new initiative looking at computational methods of multi-scale modeling that we hope will accelerate the process of designing new materials.

This initiative, funded by ARL, looks at multi-scale modeling of electronic mate- rials, part of which is for electrochemical devices. The scientists will be working with our computational team to look at a range of possibilities, from the atomic scale to the systems scale.


Right now, we can look at an atom, or we can look at a system, but it’s hard to draw the lines between them. One of the things we want is to speed up our ability to make changes.


CONCLUSION In the future, our hope is not just to make

better materials, but rather to design new types of power and energy devices that we cannot even fathom today.


We have only a small group of researchers  group, but very high-powered. Although the laboratory gives us a variety of effec- tive tools, our best resource is our people.


The ability to do research that can make a difference for Soldiers has allowed us to attract and retain top talent.


A 30 percent increase in battery energy density gives us an idea of what lies ahead.
