Scientists have uncovered a root cause of the growth of the needle-like structures that plague lithium batteries, sometimes causing a short circuit, failure or even a fire.
The devices make use of all the potential of active carbon, graphene and polyaniline, a polymer with high capabilities that is already broadly used in textile materials.
The electrode was found to improve the practical energy density of a lithium–sulfur battery to three to five times higher than that of lithium-ion batteries.
Acumentrics' portable Pack-Power device is a small, lightweight, autonomous and flexible UPS system that can be standalone or integrated into a soldier's backpack, making it suitable for defence expeditionary applications.
The Neousys PB-9250J-SA and PB-4600J-SA are standalone supercapacitor-based uninterruptible power backup modules that can protect box PCs against power outages.
Researchers have developed transparent conductive films that are set to increase the power conversion efficiency of perovskite-based multijunction solar cells beyond 30%.
By using synthetic polypeptides — which make up proteins — and other polymers, US researchers have taken the first steps towards constructing electrodes for sustainable organic batteries.
Researchers have achieved 11.4% photoelectric conversion efficiency in flexible CZTSSe thin-film solar cells — said to be the highest efficiency ever reached in such cells.
A new flexible and stretchable device, worn against the skin and capable of producing electrical energy by transforming the compounds present in sweat, has been developed.
The RAC03-K AC/DC converter, from RECOM, was designed to be the smallest 3 W solution on the market. It is a versatile converter that can be used in a wide range of applications due to complete certifications for ITE and household standards.
Tandem perovskite-CIGS solar cells have reached an efficiency of 23.26% — said to be a world record value in this type of cell.
Key components of organic solar cells require less electrical conductivity than initially thought — a breakthrough that should bring the devices closer to becoming a commercial reality.
CSIRO and Piotrek have partnered to develop the next generation of solid polymer electrolytes (SPEs) for lithium batteries.
