Summary
* Recently, an electrode for lithium ion batteries that can hold 10 times greater energy than those available in current technology was created by a group of engineers. Despite the limitations they faced to create efficient batteries such as low charge rate and weak energy capacity, they eventually succeed in improving both energy capacity and charge rate in rechargeable batteries by combining two chemical engineering processes. Lithium ions go through a certain chemical process that …show more content…
Lithium ions move from the anode to the electrolyte and finally to cathode when they are being consumed, and travel reversely when being recharged. Lithium ions also go through an oxidation process which allows them to reduce the time it takes to recharge the battery by 10times. I found this article particularly interesting because the newly developed batteries will greatly affect my life. With these efficient batteries, I do not have to worry about my phone running out of batteries and will be able to use my phone without charging it for a week. After reading the article I was curious if it will ever be possible to develop batteries that do not need charging process at all. As technological growth increases, I believe that it might be possible to develop batteries that allow phones to be powered for years. Another curiosity that rose in my mind was that if we can use batteries that can produce energy by chemical reaction, why do we use petroleum and waste natural resources instead of using battery
