“No idea”, I replied, snapping off the latex gloves. He opened his eyes, which widened in horror as black dendrite tendrils began to spread through beneath his skin. I dropped the syringe into the dish, and smoothed a plaster over the wound. He squeezed his eyes tightly shut, but felt nothing. “Hold still, just a little scratch, nothing to worry about.” Slowly, I reached out and clasped the lever. Within minutes we were at our destination. Not long to go now, thoughts turned inwards and we fell into a pensive silence. A thrill of anticipation passed through the cabin. The sun, dipping low on the far horizon, glinted from the ocean: natural sparkles of light, guiding us toward our destination.īanking steadily to the West, we saw the distant shadow of land emerging from the twilight. We flew low over the delta, the dendrite-like pattern of rivulets growing ever wider as we approached the coast. She smiled and decided that, from then on, she’d wait in the cold. She had no clue where she had read that, but everyone seemed impressed. Things took a bad turn though when the professor asked her about the damn dendrites and the only thing she could think of was “…stress induces atrophy of apical dendrites”. She didn’t need a class on Biology, but she didn’t feel like having to wait in the cold for two hours.
The researchers have applied for a patent on the technology.“…neurotransmitters that communicate with the dendrites,” said the professor standing in front of a large group of students. This technology could provide a stable, sustainable and less expensive solution. The demand for stationary energy storage systems is high and rising. So, if you suppress dendrite growth, you can charge and discharge faster, because all of a sudden it's safe." "Typically, the faster you charge, the more of these dendrites you grow. "We're essentially solving two problems at once," said study co-author David Mitlin. The process also makes the battery more stable, with a charge rate similar to a lithium-ion battery and potentially a higher energy capacity. The anode material is made by rolling a thin sheet of sodium metal onto an antimony telluride powder and folding the sheet repeatedly, resulting in a uniform distribution of sodium atoms that resist the formation of dendrites and corrosion. The team published the results in the journal Advanced Materials. This new sodium-based technology resists dendrite growth and recharges as fast as a lithium-ion battery. In sodium-based batteries, anodes can develop filaments called dendrites that could cause electrical shorts and increase the chances of a fire or explosion. Ions in batteries travel between the negative anode and positive cathode when generating electricity. National Science Foundation, have developed a sodium-based battery material that is stable, can recharge as fast as a traditional lithium-ion battery, and has the potential for a higher energy output than current lithium-ion battery technologies. Toward that end, University of Texas at Austin researchers, funded in part by the U.S. Replacing lithium and cobalt in lithium-ion batteries would result in a more environmentally and socially conscious technology, scientists say.
