The common saying goes, a good name is equal to half of the victory. Goodenough old man named it well and is quite a bit of a bad person. As the inventor of LCoO2 and LiFePO4, it can be said that there is no future for a ion battery without the task of Goodenough old man. Compared to the old man who is over 90 years old, he wrote an article on Nature Electric to review the development history of a ion battery.
Because H+ is in Sugar In the rapid expansion of daddy aqueous solution, the important thing for late-stage rechargeable batteries is to use strong acid (H2SO4) or strong (KOH) as the electrolyte. At that time, the most reliable rechargeable batteries were NiOOH as the positive and strongSugar babyManilaManilaManila escortThe volume of the electrolyte is an ozone-hydrogen battery, but we all know that the electrochemical stability window of water is very narrow, limiting the task voltage of the rechargeable battery, resulting in the energy density of the rechargeable battery using aqueous solutions is relatively low.
In order to expand the scope of electrochemical stability in electrolysis, people conducted many trials. In 1967, Joseph Kummer and Sugar babyNeill Weber of Ford Motor Company discovered that some ceramic data had Escort at high temperatures of 300°C. manila has a higher Na+ expansion rate, and used this to develop a rechargeable battery using molten gold Na negative electrode and molten S/graphite positive electrode for the machine. The high task temperature makes it difficult for the battery to find its use in reality, but this does not prevent the battery from bringing solid electrolysis technology to people, which also laid the bulge for the protrusion of tomorrow’s all-solid battery. At this time, Googenough, who was working in the Lincoln Laboratory mission at MIT, saw Sugar babyThe long-range scene of this technology was conducted on the technology, and the Na1+xZr2SixP3 with high Na+ transmission talent was developed with Henry Hong. However, because the conductivity rate of solid electrolysis was relatively low at normal temperature, it did not attract much attention at that time.
The Mara car that appeared during the oil crisis
In the 70s of the last century, an unexpected oil crisis swept over the american. At that time, the american relied on oil imports too much, so Manila escortThis oil crisis has rekindled the american society. Since then, american has begun to vigorously develop renewable power. For example, in the wind, the little girl wraps her cat with a towel and puts it into the candle, and performs training energy and solar energy to reduce dependence on fossil power such as oil. To develop wind energy and solar energy, we have to face a problem. These renewable power foundations depend on the food. It is difficult to meet the stability of the Internet. This is the advancement of the development of renewable power technology.
Metallic steel has low electrical powerEscort(-3.Sugar daddy04V vs The advantages of standard humidity electrodes) and high specific capacity (3860mAh/g) are very outstanding negative information. The late-stage primary battery uses metal steel as the negative electrode and organic solvents as the electrolyte, which has achieved good results. Therefore, the research and development of rechargeable batteries was discussed at this time.Sugar daddy began to focus on metal steel secondary electricity.On the Sugar daddy pool, researchers applied European chemists in 1960s to reversible embedding of Li+ into layer transition metal sulfides, using metal sulfides as the positive Sugar baby to prepare the last metal steril secondary battery. Moli in Canada in the last century 1980s Energy first released the Li/MO2 secondary battery that uses metal steel as the main focus to the market. This battery also made Moli Energy dominate the global battery market. Unfortunately, in 1989, the steel secondary battery experienced continuous fire and explosions, resulting in the large-scale recall of the battery in the world. From this Sugar daddy This company that short-term dominating the global battery market was in a slump and was finally acquired by the NEC company in Japan. NEC invested a lot of manpower and time to conduct a careful analysis of tens of millions of batteries, and finally found the elementary dendrite that caused the battery to explode, but it did not find a solution to the dendrite. “The way, since the safety problem could not be solved, the metal battery gradually faded out of our vision.
>Goodenough is studying LiC, a large number of Oxford in the UK. babyoO2 conducted a research and discussion. The theoretical capacity of LiCoO2 data reaches 274mAh/g, but not all Li+ can be reversible. When Li+ is dispelled for too long, it will destroy the stability of the structure and cause the collapse of the data structure. Goodenough finally achieved more than half of the reversible reversible reversible reversal Sugar babyrelease LiCoO2, making the reversible capacity of LiCoO2 data reach more than 140mAh/g. This result eventually prompted the birth of the ionic battery. LeaAkira Yoshino, who was working in Asahi Kasei, was curious about what would happen if she deviated from the so-called plot. At that time, Akira Yoshino, who was working in Asahi Kasei, used LiCoO2 as the positive, and graphite data as the negative development of the earliest ionic battery model. This technology was finally adopted by Sony, and in 1991, it released the world’s first commercial ionic battery. Steel ionic batteries use graphite data as the negative electrode to prevent the appearance of negative electrode metal, thereby preventing the innateness of steel dendrites, thus greatly improving the safety of rechargeable batteries. Since then, with the advantages of high energy density and high safety, ionic batteries have begun to move forward all the way, and have agile to leave other secondary batteries behind. In just over ten years, ionic batteries have completely occupied the consumer electronics market and expanded to the electric vehicle field, achieving brilliant results.
But the development of secondary batteries is a game that never ends. With the continuous progress of battery-specific energy indicators, traditional steel ion batteries have been unable to meet new demands. In order to further improve battery-specific energy, Goodenough, who is over 90 years old, has turned his attention to all-solid-level batteries. All-solid battery is the most promising person in our community to replace the liquid electrolysis quality in traditional steel ion batteries. After getting good grades from a small scale, the solidity of the child-transmission ability is obtained, and the strength of the solid electrolysis quality makes the metal-steel extremely happy too suddenly. The application becomes energy, leaving enough space for the advancement of the dielectric ion battery in terms of energy. After more than ten years of development, Sugar daddy‘s solid electrolysis has also developed a variety of types, such as ceramic oxide electrolysis, sulfide electrolysis and polymer electrolysis, and its functions have also been greatly improved. babyThe normal temperature ionic conductivity of some ceramic oxide electrolytics has been comparable to liquid electrolytics, making the application of all-solid battery energy. GoSugar daddyodenough, a senior student, has now applied solid electrolysis to develop an all-solid battery that has been continuously electrified during the long-term cycle.Learn functions and do not produce diazepam dendrites. Goodenough Laozi trusts that with the gradual maturity of all-solid battery technology, it will promote electric vehicles to replace traditional internal combustion engine vehicles to reduce the cost of fossil power.
Old man is in a hurry, and his ambition is thousands of miles away. At the end of his old age, the good-denominated son was still ashamed of his 96-year-old man. The door of the rescue station was narrow and old, and the head was deserted. Behind the service station, we are on the first line of scientific research tasks, how can we be lazy when we are young? Finally, we pay tribute to the Goodenough old son again.
