New spectroscopic technique could accelerate push for better batteries

A new technique could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications.

Exotic drops could lead to all-liquid battery

Through the combination of water, oil and nanoparticle surfactants plus an external field, researchers are able to stabilize water drops into non-equilibrium shapes that could find valuable uses as therapeutic delivery systems, biosensors, microfluidic lab-on-a-chip devices, or possibly as the basis for an all-liquid electrical battery.

Longest cycle life reported so far for any lithium-sulfur battery.

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated in the laboratory a lithium-sulfur (Li/S) battery that has more than twice the specific energy of lithium-ion batteries and that lasts for more than 1,500 cycles of charge-discharge with minimal decay of the battery's capacity. This is longest cycle life reported so far for any lithium-sulfur battery.

Cure for crack-prone high-capacity batteries

Researchers have shown that mixing silicon microparticles with self-healing polymers helps prevent a longer-lasting battery from failing.

Stanford engineers build basic computer using carbon nanotubes

Unprecedented feat points toward a new generation of energy-efficient electronics.

A stretchable, foldable transparent electronic display

magine an electronic display nearly as clear as a window, or a curtain that illuminates a room, or a smartphone screen that doubles in size, stretching like rubber. Now imagine all of these being made from the same material.

Water a possible key to energy storage for electric vehicles

scientists from GE and Lawrence Berkeley National Laboratory (Berkeley Lab) may have just the recipe for next-generation electric vehicle (EV) batteries that achieve desired driving range and cost for consumers.

Scientists publish theory, formula to improve plastic semiconductors

The first theoretical framework that includes molecular-level structural inhomogeneity, seeking to understand, predict and improve the conductivity of semiconducting polymers.

Just add water: possible key to energy storage for electric vehicles

A water-based, flow battery capable of more than just traditional, stationary energy storage.

Paper thin e-skin responds to touch

A research team has created the first user-interactive sensor network on flexible plastic.

Quantum Materials' tetrapod quantum dots break Kasha's Rule

Since 1950, Kasha's Rule 1, a principle of photochemistry, held true that if a source of light excited a molecule enough, the molecule would fluoresce in a single color.

Flexible energy harvesting: enabling new form factors in electronics

Flexible portable electronics, in order to retain their versatility would benefit from harvesters and batteries or supercapacitors on plastic substrates.

Composite organic/inorganic thermoelectric more than sum of its parts

Researchers have discovered highly conductive polymer behavior occurring at a polymer/nanocrystal interface.

ORNL research paves way for larger, safer lithium ion batteries

Looking toward improved batteries for charging electric cars and storing energy from renewable but intermittent solar and wind, scientists at Oak Ridge National Laboratory have developed the first high-performance, nanostructured solid electrolyte for more energy-dense lithium ion batteries.

New battery for wearable electronics

Imprint Energy, Inc based in California, USA, is developing its proprietary Zinc Poly™ batteries for small portable electronics markets, including mobile accessories, compact wireless devices, wearable technology, health and fitness monitoring, and medical devices.
