New Battery is Cheap, Clean, Rechargeable, and Organic

Scientists at USC have developed a water-based organic battery that is long-lasting, and built from cheap, eco-friendly components. The new battery — which uses no metals or toxic materials — is intended for use in power plants, where it can make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as needed.

Power for Extreme Environments

Specifying the ideal power management solution for remote wireless devices found in extreme environments and hard-to-access locations requires more ruggedized solutions. Fortunately, two viable options are now available: lithium thionyl chloride (LiSOCL2) chemistry that can operate for 40+ years, and energy harvesting devices coupled with special rechargeable lithium-ion batteries designed for extreme environments that can deliver up to 20+ years of battery life. Lithium thionyl chloride chemistry is proven for use in extreme environments.

Nanomaterial Extends Lithium-Sulfur Battery Lifespan

A new nanomaterial could extend the lifespan of lithium-sulfur batteries, and therefore the driving range of electric vehicles.Pacific Northwest National Laboratory researchers added the powder to the battery's cathode to capture problematic polysulfides that usually cause lithium-sulfur batteries to fail after a few charges.Metal organic frameworks — also called MOFs — are crystal-like compounds made of metal clusters connected to organic molecules, or linkers. Together, the clusters and linkers assemble into porous 3-D structures. During lab tests, a lithium-sulfur battery with PNNL's MOF cathode maintained 89 percent of its initial power capacity after 100 charge-and discharge cycles. Having shown the effectiveness of their MOF cathode, PNNL researchers now plan to further improve the cathode's mixture of materials so it can hold more energy.SourceAlso: Check out other Materials tech briefs.

Self-Charging Power Cell for Small Devices

A hybrid power cell uses a new technique for electrical charge conversion and storage. Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.
