Scientists in the United States, published in the latest issue of the journal science progress paper said that the lithium ion battery of lithium ion concentration fluctuation happens, which explains the reason of the lithium ion battery life shorter, is expected to help develop faster charging, the battery standby time longer.

Led by the U.S. department of energy (doe) brookhaven national laboratory, a team of researchers has found that when the battery when an electrical current, if the battery's electrodes are made of nanoparticles, nanoparticles in the area of the lithium ion concentration will first increase, then down, rather than had been thought of concentration will continue to increase.

A lattice is a structure in which particles within a crystal are arranged in geometric patterns. The lithium ion battery works by moving lithium ions between the positive and negative poles. When charged, lithium ions flow from the positive to the negative poles and discharge in the opposite direction.

"Is just like a sponge, we see the nanoparticles in the lithium ion concentration increasing," presided over the research of brookhaven national laboratory for sustainable energy technology scientist wang feng said, "but unlike water, lithium ion can selectively in some zone, lithium ion concentration between the lattice caused by inconsistent."
    
 
    Therefore, in the process of lithium battery production, it is necessary to use the lithium battery mixer to fully mix the lithium battery materials and make the crystal arrangement more detailed.

The researchers point out that the lattice is uniformly structured before the lithium ions enter it, stretching it once they enter it, and then shrinking as the lithium ions flow out. The uneven movement of lithium ions may cause lasting damage because it deforms the structure of active components in the battery and may lead to battery fatigue and failure.

The researchers speculate that this could also happen with chemicals in other high-performance batteries, which could help develop batteries with shorter charging times and longer standby times。
