Rice Husks Could Lead to Longer Battery Life

Rice Husks Could Lead to Longer Battery Life

An agricultural waste product, such as rice husks, is an unlikely source for a material that could lead to better, and longer lasting, batteries. But the results of a recent study suggest that those same rice husks could one day be used to produce silicon anodes for lithium batteries. Researchers at the Korea Advanced Institute of Science and Technology (KAIST) were recently able to convert the silica from rice husks into pure silicon, and then fashioned it into anodes for a high-capacity lithium-ion battery. The resulting battery exhibited no reduction of capacity after 200 charge cycles, which suggests that the… read more

Greener Batteries Could Be Made From Plants

Greener Batteries Could Be Made From Plants

The roots from a plant may someday be used to make greener batteries. That is what scientists who discovered that purpurin, a substance that can be extracted from the root of the madder plant, found. The group of researchers learned that it is possible to make rechargeable lithium ion batteries from this material as it can be implemented as a natural cathode. The plant, categorically known as Rubia tinctorum, has traditionally been used as a natural dye. When examining ways to use organic molecule properties and their capacity to work with lithium ion, they discovered purpurin’s effectiveness as a better rechargeable… read more

3D Printed Batteries as Small as a Grain of Sand

3D Printed Batteries as Small as a Grain of Sand

In the quest for smaller and smaller devices, some of our technology has kept pace, while others, such as tiny batteries for mobile devices, have not. But a recent breakthrough of a microbattery the size of a grain of sand hints at the next generation of tiny energy storage devices. A team of researchers have successfully built a tiny lithium-ion microbattery by using a 3D-printer to precisely print interlaced stacks of electrodes that are thinner than a human hair. The team, based at Harvard University and University of Illinois at Urbana-Champaign, first developed specialized inks that are both electrochemically active… read more

Recharging Non-Rechargeable Batteries

Recharging Non-Rechargeable Batteries

Batteries are one thing that a lot of us depend on. Many people don’t know that a potential charge or two can be left behind in alkaline batteries that were thought to have run their course. There are products available to help extract that last bit of power, and you can also make your own battery reviver at home with a few supplies to extend their lifespan and also prolong their trip to the recycler for as long as possible. The Battery Wizard for alkaline batteries is one example of a product on the market to bring back non-rechargeables another… read more

Solid Lithium-Sulfur Battery Offers 4X the Energy Density of Li-Ion

Solid Lithium-Sulfur Battery Offers 4X the Energy Density of Li-Ion

A new type of battery that has four times the energy density of current lithium-ion batteries, yet uses a low-cost material, has been developed and tested at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL). The development of this new all-solid lithium-sulfur battery could lead to lower costs for energy storage, safer batteries, and increased energy density, and may lead to a sea change in mobile power for everything from portable gadgets to electric vehicles. Previous approaches to lithium-sulfur batteries were plagued by their use of a liquid electrolyte in the design, which caused premature failure in the… read more
