Everyone has faced the problem of decreasing rechargeable battery capacity. Whether it's a mobile phone or a laptop, it will ultimately depend on the charger and be barely portable. This is a problem that scientists have been trying to solve because they also cannot figure out what causes the rapid deterioration of the battery.
But researchers at the U.S. energy department have determined that the rechargeable battery gradually loses its capacity over time. Lithium-ion batteries are the most common type of consumer electronics device. Researchers look for the key by observing the charge and discharge processes in a microscopic state. "First, the hole in the microstructure of the battery material is used to guide lithium ions through randomly and corrode the battery in a random manner. This defect is very much like the rust is covered on the steel pipe. The second study, focusing on Looking for the best balance between voltage, storage capacity, and maximum charge cycle, the researchers discovered a similar problem with ion currents. After the chemical reaction, nanometer-sized tiny crystals were left behind, and crystals accumulated after charging, resulting in more fluid ions. Regular use of batteries with higher voltages will lead to more ion channel misbehavior, which will lead to more rapid deterioration of the battery."
But the research team is optimistic that they will study more durable, more compact and more powerful battery technologies. Cell phones and laptop batteries can maintain maximum performance for about three years, while for electric cars, rechargeable batteries should last at least 10 to 15 years. The team hopes that their research will enable the battery of electric vehicles to maintain their highest performance for more than thirty years.
