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

iBattz has unveiled a slew of accessories aimed at smartphone and tablet owners at this year’s CES. These include a wireless charging station for Samsung Galaxy S III and Galaxy Note II, a rugged battery-packed case for iPhone 5 and iPad, and a trio of iPhone 5 cases which feature interchangeable batteries.  Read More

GE has unveiled its Durathon sodium battery, which should allow for improved performance a...

General Electric’s research team has unveiled its new Durathon battery, which the company says makes it cheaper to power buses using clean energy. It is used in tandem with a lithium battery and a hydrogen fuel cell, a combination that the researchers say makes it possible for the vehicle to achieve full performance with a much smaller fuel cell than previously possible.  Read More

The Optisort battery-sorting machine

While it’s definitely important to keep the heavy metals in discarded batteries out of the environment, the sorting of all of the different types of batteries that arrive at a recycling depot could no doubt get extremely tedious. It’s the type of job that often goes to a machine. Well, such a machine has been invented. Called the Optisort, it can recognize about 2,000 types of batteries, and is currently being used to sort one third of those recycled in the UK.  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 red dots show the iPhone 5’s power amplifiers, which account for 60 percent of total p...

Cell phones have come a long way in terms of battery life, but lets be honest, there's still plenty of room for improvement. The very fact that we talk about using a phone for eight hours as being good is, well, bad. While next-gen battery technologies present one solution to the dilemma, a new breakthrough from MIT spinoff Eta Devices takes a different tack – by improving power amplifier efficiency the company hopes to double the battery life of smartphones.  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
