Although the development of mobile phone updates is extremely fast, the development of mobile phone batteries is relatively slow. According to survey data, the capacity of batteries only increases by 10% every 10 years. It is almost impossible to significantly increase the capacity of mobile phone batteries in the short term, so there is also infinite potential and potential in the field of mobile phone batteries.

　　The 2019 Nobel Prize in Chemistry was awarded to Professor John Goodinaf, Professor Stanley Wittingham, and Dr. Yoshino Akira for their outstanding contributions in the field of lithium-ion batteries. Professor John Goodinaf is currently the oldest Nobel laureate, and before their awards, people predicted every year whether lithium-ion batteries would be awarded. The progress of lithium-ion batteries has had a significant impact and contribution on society, and their awards are truly deserved.

　　In the 1970s, the Middle East War led to the oil crisis, and people began to realize the importance of getting rid of oil dependence. They began to invest in new energy sources that could replace oil, and the enthusiasm of countries in developing batteries was also high. Gudinav was deeply affected by the oil crisis and hoped to make contributions in energy substitution.

　　When using pure lithium as the anode to charge a battery, it can lead to the formation of lithium dendrites, which can cause short circuits, fires, and even explosions in the battery. However, researchers have never given up on researching lithium batteries.

　　The three Nobel laureates: Stanley Wittingham developed a rechargeable lithium battery that can work at room temperature in the early 1970s. It is a more comprehensive lithium battery that utilizes lithium to release its powerful driving force of outer electrons;

　　Weitinghan's batteries can generate slightly more than 2 volts of voltage. In 1980, Gudinov discovered that batteries using lithium cobalt oxide as a material in the cathode can produce a voltage that can be doubled. He doubled the potential of the battery. The high-energy density cathode material has a light component, but can produce more powerful batteries. This development of more practical batteries has created better conditions.

　　In 1985, Yoshino Akira developed a commercially available lithium-ion battery. He chose lithium cobalt oxide used by Goodinaf as the cathode and successfully replaced lithium alloy with carbon as the negative electrode. He developed a lithium battery with stable operation, light weight, and a slightly large capacity. This type of battery became safer and greatly reduced the risk of spontaneous combustion.

　　It is their research that has propelled lithium batteries into countless electronic products, allowing us to enjoy modern mobile life. Lithium batteries have created suitable conditions for a wireless, fossil fuel free new society.
