Sandia National Laboratories and the U.S. Department of Energy have released a new tool to help utilities, developers, and regulators identify the energy storage options that best meet their needs. Partnering with DNV KEMA, Sandia is releasing Energy Storage Select, or ES-Select, software under a public license to the company.

For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led by materials scientist has found a solution: a cleverly designed double-walled nanostructure that lasts more than 6,000 cycles, far more than needed by electric vehicles or mobile electronics.

Separators for lithium-ion batteries can be evaluated effectively
when scanning probe microscopes are used in conjunction with tensile
testing instruments.

While
working with an enzyme found in bacteria that is crucial for capturing
solar energy, researchers in Michigan have found they can adjust the
time the battery-like enzyme can store energy. In nature, the enzyme
recovers from a charge-separated state in seconds, but changing the
enzyme’s shape has extended storage to several hours.

SustainX,
a grid-scale developer of energy storage solutions, is commercializing
isothermal compressed air energy storage, which is typically
accomplished using underground caverns. However, this new technology,
licensed from the University of Minnesota, uses pipe-type air storage,
which makes it possible to store energy in more places.

In
prototypes of the lithium-sulfur battery, lithium ions are exchanged
between lithium- and sulfur-carbon electrodes. The sulfur is an
excellent energy storage material due to its low weight. At the same
time, sulfur is a poor conductor, so researchers have a devised a way to
greatly improve conductivity using a porous network of carbon
nanoparticles.

For catalysts in fuel cells and electrodes in batteries, engineers would like to manufacture metal films that are porous, to make more surface area available for chemical reactions, and highly conductive, to carry off the electricity. The latter has been a frustrating challenge. But Cornell University chemists have now developed a way to make porous metal films with up to 1,000 times the electrical conductivity offered by previous methods.

It turns out you can be too thin—especially if you're a nanoscale battery. A team of researchers built a series of nanowire batteries to demonstrate that the thickness of the electrolyte layer can dramatically affect the performance of the battery, effectively setting a lower limit to the size of the tiny power sources.
