Lithium-ion

Scientists have developed a stretchable lithium-ion battery, that could be used to power s...

Thanks to the advent of stretchable electronics, we’re currently witnessing the development of things like smart fabrics, bendable displays, and even pressure-sensitive skin for robots. In many potential applications, however, the usefulness of such electronics would be limited if they still had to be hooked up to a rigid battery. In response to that problem, a team of scientists have recently created – you guessed it – a stretchable lithium-ion battery.  Read More

Scientists have used etched silicon nanoparticles in the anode of a next-generation lithiu...

In some peoples’ opinion, electric cars won’t become truly viable until their batteries offer a lot more driving range, and can be recharged much more quickly than is currently possible. Well, those people may soon be getting their wish. Scientists at the University of Southern California have developed a new type of lithium-ion battery, that they claim holds three times as much energy as a conventional li-ion, and can be recharged in just ten minutes.  Read More

Researchers have found an eco-friendly alternative to the metal ores currently favored in the electrodes of lithium-ion batteries. The new non-toxic and sustainable battery uses purpurin, a red/yellow dye extracted from the root of the madder plant that has been used for dying cloth for at least 3,500 years – meaning the substance can simply be grown rather than mined.  Read More

Researchers at Rice University and Lockheed Martin may have developed a low-cost method of creating longer-lasting, high-capacity lithium-ion batteries. Currently graphite is used as the anode in commercial li-ion products, despite the fact that a silicon anode could potentially store ten times more lithium ions. The team says it has solved one of the problems associated with silicon, which nearly triples the energy density of current li-ion batteries.  Read More

The single biggest factor hindering the convenience, and therefore the adoption, of electric vehicles is the batteries used to power them. While filling up an ICE vehicle takes just a few minutes at the pump, electric vehicle recharge times are measured in hours. Engineers at the University of California, San Diego, have developed new algorithms that improve the efficiency of existing lithium-ion batteries and could allow them to be charged twice as fast than is currently possible.  Read More

Researchers from the Tokyo University of Science have found pyrolyzed sucrose to be a surp...

Researchers at the Tokyo University of Science have turned to sugar as part of a continuous effort to control Japan's growing import costs associated with building lithium-ion batteries. It seems that sugar may be the missing ingredient for building rechargeable batteries that are more robust, cheaper, and capable of storing more energy.  Read More

Boosted Boards markets its longboard as a “last mile” transport system

San Francisco-based startup Boosted Boards has produced an eponymous electric skateboard prototype capable of providing a push-free ride for up to 6 miles. While an electric skateboard isn't anything new in itself, this particular longboard is declared by its makers to be the world's lightest electric vehicle.  Read More

The cable-like flexible batteries being developed by LG are achieving promising performanc...

We've covered our fair share of flexible electronics, but as far as bendability goes, the flexible batteries developed by LG are truly raising the bar by a couple of notches. The Korean company is working on a battery that is shaped like a cable, and can be bent, tied, or even woven into fine sheets with almost no loss in discharge performance.  Read More

While the lithium-ion batteries commonly used in electric cars are capable of storing a fairly large amount of energy, they’re not able to accept or discharge that energy very quickly. That’s why electric vehicles require supercapacitors, to speedily deliver energy when accelerating, or to store it when braking. Recently, however, researchers from New York’s Rensselaer Polytechnic Institute created a new anode material, that allows Li-ion batteries to charge and discharge ten times faster than those using regular graphite anodes. It could make EV supercapacitors unnecessary, and vastly shorten the charging time required by electronic devices.  Read More

A newly developed bendable thin-film lithium-ion battery could help bridge the gap to high...

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have developed a promising solid state, thin-film lithium-ion battery that claims the highest energy density ever achieved for a flexible battery. The new design, which showed for the first time that high-performance thin films can be used for flexible batteries, may be commercialized as early as next year.  Read More
