Trapped electrons to blame for lack of battery efficiency

Research has the potential to create more efficient batteries by shedding light on the cause of one of their biggest problems -- a "traffic jam" of ions that slows down their charging and discharging process.

Improved 3-D-printed graphene aerogel supercapacitors

Researchers have devised a method for doubling the performance of 3-D-printed graphene-based supercapacitors.

Wearable sensing technology for heart failure patients

Scientists are working to address heart failure issues by building wearable and weighing-scale-based ballistocardiogram technology for monitoring heart failure patients at home.

Extend life and improved performance of fuel cell electrodes

Researchers have developed a practical and physically-based way of treating the surface of materials called perovskite oxides, to make them more durable and improve their performance. These materials are promising candidates to serve as electrodes in energy-conversion devices such as fuel cells and electrolyzers.

24m Technologies

24M is a spin-out of battery company A123 that has developed a semi-solid, flexible electrode structure for their Li-ion batteries. We recently interviewed President and CEO Throop Wilder.

Scientists design energy-carrying 'Topological Plexcitons'

Scientists have engineered "topological plexcitons," energy-carrying particles that could help make possible the design of new kinds of solar cells and miniaturized optical circuitry.

Novel capping strategy improves stability of perovskite nanocrystals

Perovskite materials have shown great promise for use in next-generation solar cells, light-emitting devices, sensors, and other applications, but their instability remains a critical limitation.

PolyPlus Battery Company

Polyplus is a US company that develops solid-state and semi-solid state electrolytes for lithium-air, lithium-sulphur and advanced lithium-ion batteries. After 20 years of R&D, they are now ready to enter both military and consumer electronics applications.

Seeo

Seeo is a US battery start-up that was recently acquired by Bosch. They have developed an innovative solid polymer electrolyte that can be coupled with lithium metal to boost gravimetric and volumetric energy density, while making the device safer.

New path forward for next-generation lithium-ion batteries

In the quest for a radically better lithium-ion battery, a promising direction is the so-called "lithium-rich" cathode, in which the cathode contains a higher proportion of lithium than normal.

First step toward flexible, wearable, tricorder-like device

Engineers have developed the first flexible wearable device capable of monitoring both biochemical and electric signals in the human body.

Nanomaterial to drive new generation of solar cells

Physicists have discovered radical new properties in a nanomaterial, opening new possibilities for highly efficient thermophotovoltaic cells that could one day harvest heat in the dark and turn it into electricity.

Graphene nanoflake-based films developed as thermal interface material

Heat dissipation in electronics and optoelectronics is a major obstacle to further technology development. It limits further miniaturisation, power, performance and reliability.

Cambrios restarts Its silver nanowire business

Champ Great has formed a new company, Cambrios Advanced Materials Corporation that will continue research, development and sales of silver nanowire inks.

Adaptive protein crystal could form new kind of protective material

Stretching or compressing the material in one direction causes the connected protein tiles to rotate in unison, resulting in a corresponding expansion or contraction in the opposite directions.

New catalyst offers efficient storage of alternative energies

Researchers have designed the most efficient catalyst for storing energy in chemical form, by splitting water into hydrogen and oxygen, just like plants do during photosynthesis.

Battery technology with off-the-charts charging capacity

Researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement.
