"People ask me: why hemp? I say, why not?" said Dr David Mitlin of Clarkson University, New York, who describes his device in the journal ACS Nano. "We're making graphene-like materials for a thousandth of the price - and we're doing it with waste. ... the leftover bast fibre - the inner bark - typically ends up as landfill. "You can do really interesting things with bio-waste. We've pretty much figured out the secret sauce of it," said Dr Mitlin. The trick is to tailor the right plant fibre to the right electrical device - according to their organic structure. "With banana peels, you can turn them into a dense block of carbon - we call it pseudo-graphite - and that's great for sodium ion batteries," he explained. "But if you look at hemp fibre its structure is the opposite - it makes sheets with high surface area - and that's very conducive to supercapacitors." Mitlin's peer-reviewed journal paper ranks the device "on par with or better than commercial graphene-based devices". "They work down to 0C and display some of the best power-energy combinations reported in the literature for any carbon. Fully assembled, their energy density is 12 Wh/kg, which can be achieved at a charge time less than six seconds. "Obviously hemp can't do all the things graphene can," Dr Mitlin concedes. "But for energy storage, it works just as well. And it costs a fraction of the price – $500-1,000 a tonne."

Scientists may have created the very first solar battery. Researchers have succeeded in combining a battery and a solar cell into one hybrid device, which could be huge in terms of renewable energy capture and storage. "The state of the art is to use a solar panel to capture the light, and then use a cheap battery to store the energy," said Yiying Wu, one of the researchers, in a news release. "We've integrated both functions into one device. Any time you can do that, you reduce cost." The key to the new device is a mesh solar panel, which allows air to enter the battery. There's also a special process for transferring electrons between the solar panel and the battery electrode; inside the device, light and oxygen enable different parts of the chemical reactions that charge the battery. "Basically, it's a breathing battery," said Wu. "It breathes in air when it discharges, and breathes out when it charges." The mesh solar panel forms the first electrode. Beneath the mesh is a thin sheet of porous carbon, which acts as the second electrode, and a lithium plate, which acts as the third electrode. Between the electrodes are layers of electrolyte to carry electrons back and forth. During charging, light hits the mesh solar panel and creates electrons. Then inside the battery, electrons are involved in the chemical decomposition of lithium peroxide into lithium ions and oxygen. The oxygen is released into the air, and the lithium ions are stored in the battery as lithium metal after capturing the electrons. The findings could be huge in terms of creating sustainable energy for powering a variety of devices. Currently, the researchers are continuing to move forward in improving the efficiency of the battery and the amount of power the panel can absorb and convert. The findings are published in the journal Nature.
