#Nanoparticle network could bring fast-charging batteries (Phys. org) A new electrode design for lithium-ion batteries has been shown to potentially reduce the charging time from hours to minutes by replacing the conventional graphite electrode with a network of tin-oxide nanoparticles.
The anodes in most of today's lithium-ion batteries are made of graphite. The theoretical maximum storage capacity of graphite is limited very at 372 milliamp hours per gram hindering significant advances in battery technology said Vilas Pol an associate professor of chemical engineering at Purdue University.

Salt ions, in contrast, are larger than water molecules and cannot cross the membrane. The porous membrane allows osmosis,
The membrane allowed rapid transport of water through the membrane and rejected nearly 100 percent of the salt ions, e g.,
including irradiation with electrons and ions, but none of them worked. So far, the oxygen plasma approach worked the best,
the researchers etched micrometer scale pillars into a silicon surface using photolithography and deep reactive-ion etching,
Sporting higher energy density than lithium-ion we may even see batteries made with this material.
Performance of sol-gel thin film electrodes at Georgia Tech's laboratories has exceeded all existing commercial electrolytic capacitors and thin-film lithium-ion batteries.
Mass-Selected Photoelectron Circular Dichroism (MS-PECD) uses circularly polarised light produced by a laser to ionise the molecules using a couple of photons to knock an electron out of the chiral molecule to leave a positively charged ion behind.
which a small electrical potential is applied to the negatively charged electron and positively charged ion which draws them out in opposite directions.
The scientists look for simultaneous detection of the ion and electron those reaching the detectors simultaneously are very likely to have come from the same molecule.
The mass of the ion can be measured and matched with its partner electron. By combining these methods,
