![]() It turns out that ethylene carbonate leaves the battery vulnerable to damage.Ĭatching fast-moving action inside lithium batteries Further, the scientists pinpointed a culprit in the growth process: ethylene carbonate, an indispensable solvent added to electrolyte to enhance battery performance. ![]() The PNNL team found that the origin of whiskers in a lithium metal battery lies in a structure known as the "SEI" or solid-electrolyte interphase, a film where the solid lithium surface of the anode meets the liquid electrolyte. Dendrites and whiskers are holding back the widespread use of lithium metal batteries, which have higher energy density than their commonly used lithium-ion counterparts. They also increase unwanted reactions between the electrolyte and the lithium, speeding up battery failure. Both cause tremendous harm notably, they can pierce a structure known as the separator inside a battery, much like a weed can poke through a concrete patio or a paved road. 14 in Nature Nanotechnology.ĭendrites are tiny, rigid tree-like structures that can grow inside a lithium battery their needle-like projections are called whiskers. The team hopes the discovery will lead to new ways to prevent their growth by manipulating the battery's ingredients. It does not store any personal data.The team, led by Chongmin Wang at the Department of Energy's Pacific Northwest National Laboratory, has shown that the presence of certain compounds in the electrolyte - the liquid material that makes a battery's critical chemistry possible - prompts the growth of dendrites and whiskers.

Within dementias, this is the most common, especially in older people, and is the fourth leading cause of death in adults. It is a disease that affects the nerve cells in the different regions of the brain, causing dysfunction in it such that the individual loses all ability to control his emotionsrecognize patterns, coordinate movements and remember things. This sickness it is of a progressive type and a form of recovery is not yet known for her. This new discovery could be fundamental when studying ways to cure or prevent diseases of this type, such as Alzheimer's. This is due to the fact that a minimum error in the coding of the RNA could result in a protein malformation that could harm the brain circuits that allow the normal functioning of the memory, inevitably affecting it. This would reveal the fundamental role of these nerve extensions in the process of the memory and the learning and turn them into a fundamental element when it comes to triggering neurodegenerative diseases. ![]() Thanks to a study carried out in the University of Pennsylvaniait has been discovered that the work of the dendrites is not only restricted to receiving and sending chemical and electrical signals but they can also to create proteins (Before it was believed that the only area of the cell where it could be done was the nucleus). The role of dendrites in neurodegenerative diseases Another use of the notion is found in the engineeringwhere the dendrite is a metallic crystal that is produced by solidification and whose structure resembles a tree with many branches. The term can then be used to refer to the mineral structure which, with an appearance similar to the branches of trees, appears in the cracks and joints of rocks. It should be noted that the dictionary of the Royal Spanish Academy (RAE) accepts other uses of the dendrite concept.
