Comments Off on Researchers close in on world’s first 100% self-charging lithium-ion battery

We’ve all experienced the nuisance of a dying phone when there’s no outlet in sight, but that moment could become a relic of the past thanks to new technology being developed by an international team of 19 scientists. The group, led by the Institute de Recherche d-Hydro-Québec and McGill University in Canada , want their battery to harvest and store light energy all on its own – without the help of solar panels . Lithium-ion batteries can only hold so much power, and must be recharged often. So researchers are developing a device that can harvest energy from light and store it. They just published a study showing a lithium-ion battery cathode can be sensitized to light by combining lithium-ion materials with dye molecules including solar cell technology. Here’s how study lead author Andrea Paolella of Hydro-Québec puts it: “In other words, our research team was able to simulate a charging process using light as a source of energy.” Related: 94-year-old inventor of lithium-ion cells develops new battery that can store 3 times more energy The cathode is only half of the process. The researchers must develop an anode that can store the light energy. If they can accomplish that feat, they will have created the first 100 percent self-charging lithium-ion battery in the world. And they’re already at work on phase two. “I’m an optimist and I think we can get a fully working device. Theoretically speaking, our goal is to develop a new hybrid solar-battery system, but depending on the power it can generate when we miniaturize it, we can imagine applications for portable devices such as phones,” said Paolella. Phase two could still take years, but co-author George Demopoulos, a professor at McGill University, thinks this passive form of charging could be significant for devices of the future. Nature Communications published the study online earlier this month. Scientists from institutions in Italy, Spain, and the United Kingdom were also part of the research.

Comments Off on Seoul’s multi-tiered Deep House slopes into a gorgeous grassy roof

This house in South Korea’s capital utilizes negative space to create various micro-environments that boost the building’s energy efficiency. Architecture firm poly.m.ur designed the Deep House as a single volume featuring a slanted roof and walls where one room flows into another. The tilted roof provides ample storage inside and gives each residential unit expansive views of the surroundings. The house features a slanted roof and stone louvers along the sloping sides of the building. Taking inspiration from a design philosophy based on the idea of dispersing the main volume through the use of shallow depth, the architects created hollow spaces that improve the energy efficiency of the building and provide ample storage space . Related: Angular residence by Moon Hoon maximizes privacy and a tiny plot Box-type corner windows are strategically laid out to provide optimal views of the surrounding landscape while minimizing the effects of cold winter winds. Instead of treating windows as two-dimensional elements, the architects conceived them as “micro-spaces” or “rooms inside rooms”. + poly.m.ur Via Archdaily Photos by Kyungsub Shin

Photo via Shutterstock Researchers at the University of California have developed a new lithium-ion battery that recharges in just 10 minutes and holds three times as much energy as its existing counterparts. By using porous nanotubes , researchers made the silicon expand and contract without breaking, which allows lithium-ions to diffuse more quickly and improve the battery performance. The design is currently under a provisional patent and could be on the market in just two to three years.
