German researchers Technical University of Munich (TUM) have been looking at what makes your batteries die so quickly.
In particular, the researchers looking at lithium-ion batteries, the type you can find in your phone, laptops and even some aircraft and electric vehicles, which will eventually lose charge capacity over time by sending you to buy a new battery for the laptop (or whatever your gadget), or wondering why your life is the battery lasts less time after several years.
University explains that the lithium-ion batteries with graphite anodes (an electrode through which the conventional current), losing much of its capacity for the very first charge cycle, largely due to the active component of the lithium is consumed when “pacifying layer anode “forms.
This soothing layer protects the battery electrolyte from decomposing at the anode.
Each charge after reduces the ability, although it fairly quickly, while the power can also be lost even without charging the battery, but simply to keep them, and especially in these conditions at room temperature.
Researchers at TUM say that while others could not find a definitive answer why aged battery in such a matter, they come one step closer, “Closing this knowledge gap.”
The command is used electrochemical studies, and “X-ray diffraction” and temperature effects during the experiments.
Scientists have discovered that the loss of power occurred due to active consumption of lithium occurred at higher temperatures and higher voltages increase conductivity soothing layer and therefore decomposition of the electrolyte.
these findings, researchers believe that some additives may be used to alter the method pacifying layer is formed so that the active lithium is not affected, thereby maintaining the battery capacity.
“With our ideas, are now separate processes can be improved,” says Irmgard Buchberger, a graduate student at the Department of Electrochemistry at TUM
