Its design is based on the inner structure of the fruit, giving it a long life
American researchers from Stanford University created an electrode that resembles the pomegranate's internal structure and could prolong the life of the gadget battery and other gadgets.
«While there are still some proscalls τις οποίες καλούμαστε να λύσουμε, παρόλα αυτά το συγκεκριμένο σχέδιο μας φέρνει πιο κοντά στη δημιουργία πανίσχυρων και ταυτόχρονα μικρότερων και ελαφρύτερων batteries for devices such as smartphones, tablets and electric cars"Explains the professor and head of the study Yu Kui.
«From experiments it appeared that the anode electrode inspired by pomegranate is capable of operating at 97% even after 1.000 charging-discharge cycles, making it suitable for commercialization"The expert says.
Battery in ... "clusters"
The anode or negative electrode is the point where energy is stored when charging the battery. A silicon anode, according to the scientists, is capable of storing up to 10 times more charge energy compared to a graphite anode in today's lithium-ion batteries.
However, the silicon anode is more brittle than the graphite one, causing it to break during charging while appearing to react with the battery electrolytes. To address the problem, the team by Dr. Cui, replaced the silicon anode with clusters of silicon nanowires, which could resemble pomegranate pimples. These clusters are enclosed in a protective cover within which the nanowires have the space to contract and expand when they receive an electrical charge.
Interesting findings are published in the "Nature Nanotechnology».
