Superoxide gives lithium-air batteries a jolt
In a recent experiment, Argonne battery scientists Jun Lu, Larry Curtiss and Khalil Amine, along with American and Korean collaborators, were able to produce stable crystallized lithium superoxide (LiO2) instead of lithium peroxide during battery discharging. Unlike lithium peroxide, lithium superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life.

A simple way to make lithium-ion battery electrodes that protect themselves
Scientists at three Department of Energy national laboratories have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing technique to form the cathode material into tiny, layered particles that store a lot of energy while protecting themselves from damage.

Unique 2-level cathode structure improves battery performance
A team of scientists from the US Department of Energy's (DOE) Brookhaven National Laboratory, Lawrence Berkeley National Laboratory, and SLAC National Accelerator Laboratory say they've found a way to make a battery cathode with a hierarchical structure where the reactive material is abundant yet protected -- key points for high capacity and long battery life.

Technique matters: A different way to make cathodes may mean better batteries
Lithium nickel manganese cobalt oxide, or NMC, is one of the most promising chemistries for better lithium batteries, especially for electric vehicle applications, but scientists have been struggling to get higher capacity out of them. Now researchers at Lawrence Berkeley National Laboratory have found that using a different method to make the material can offer substantial improvements.

How seashells get their strength
Seashells and lobster claws are hard to break, but chalk is soft enough to draw on sidewalks. Though all three are made of calcium carbonate crystals, the hard materials include clumps of soft biological matter that make them much stronger. A study today in Nature Communications reveals how soft clumps get into crystals and endow them with remarkable strength.

Lab researcher helps team that may have a key solution to reducing carbon dioxide emissions
Meeting the Paris Climate Agreement goal of limiting the increase in the global average temperature to well below two degrees Celsius compared to pre-industrial levels will require increased use of renewable energy and reducing the CO2 intensity of fossil energy use.

Renewable energy for state renewable portfolio standards yielded sizable benefits
A new study estimates that billions in dollars in benefits come from reduced greenhouse gas emissions and from reductions in other air pollution for state renewable portfolio standard policies operating in 2013. RPS policies require utilities or other electricity providers to meet a minimum portion of their load with eligible forms of renewable electricity.

Nature's masonry: The first steps in how thin protein sheets form polyhedral shells
Scientists have for the first time viewed how bacterial proteins self-assemble into thin sheets and begin to form the walls of the outer shell for nano-sized polyhedral compartments that function as specialized factories. The new insight may aid scientists who seek to tap this natural origami by designing novel compartments or using them as scaffolding for new types of nanoscale architectures, such as drug-delivery systems.
