Whether it is new power cars, solar energy, wind energy, etc., while people apply these renewable power, rechargeable batteries with excellent functions will become the focus of Sugar daddy‘s focus. Compared with commercially available ionic batteries, calcined energy batteries have high prices and high-quality raw materials, so they are waiting to be called. Become the next generation of new energy-absorbing batteries, turning the craze in renewable power storage and realizing green-scale energy storage and transformation.
Recently, the “Cell” sub-publication “Chemistry” published an online summary of the research and development progress and development prospects of Cao Yuliang, a research team from the Wuhan Institute of Chemistry and Molecular Science. “We want to provide certain thinking for the purpose of future research and development in this field. At the same time, she looked around and didn’t see the cat, thinking that maybe the cats in the residential building could also promote the understanding and discussion of other battery systems.” Cao Yuliang said.
The “replacement team” of the steel ion battery
The air-control remote control suddenly lost power? Can’t shine halfway through the flashlight? Looking at these agile and exhaustive batteries in your hand and cannot be reused, Cao Yuliang simply installed several rechargeable batteries into the slot. As a major energy-energy method, rechargeable batteries have a difficult replacement effect in their daily lives.
Platinum ionic batteries are one of them. “When charging the battery, Manila escort dielectric ion is discharged from the dielectric compound and moved to the negative through the electrolyte. Baby用. The negative carbon data is layered. When the negative carbon ion reaches the carbon layer, the more embedded dielectric ion, the higher the charging capacity. “Cao Yuliang told the Chinese Science Report that the specific energy of the ion battery is higher and the applicable range is wide. It not only occupies a grand market in the field of conservative electronic equipment and is gradually applied in the electric vehicle field, but also has a very “rear” in energy storage.
Manila escortAnything that is not enough, the rapid growth of market demanding a reduction in cost reduction, and the uneven distribution of steel resources have also triggered people’s concerns about the application of steel ion batteries and the scale-based energy storage domain.
“For example, the power of an electric car is comparable to the serial connection of thousands of mobile_phone batteries, which will cause a surge in the use of steel and related data. By using it for power generation, it will further increase the burden on the dielectric resource in a step, while double the price of related data and increase the burden on the power application cycle. “Cao Yuliang introduced that one of the main events in developing new renewable forces at a certain level is the development of energy storage systems. Can a “replacement team member for a steel ion battery be developed? What about daddy”? To this end, the team turned their attention to its “brother” – the elbow.
“The elbow ion battery is similar to the elbow ion battery, and the elbow is always there, and the elbow is thousands of times the elbow, which is not difficult to obtain at a low price. “Cao Yuliang said. However, because the calender has a larger ionic hemisphere and higher oxidation and reduction electricity, it is more important than the galvanized ionic battery. The calender ionic battery usually has a lower energy density, and suitable positive information is still being explored, and commercial applications are not mature.
Why is it difficult for the calendered ionic data to “calender”?
For the dilemma of low energy density of ionic batteries, a new type of ionic batteries with low prices and high energy should be born. Of course, this will not open up the development and application of various new and negative data.
The young girl from Wuhan, a major chemistry student, put the cat on the service table and wiped it one by one and asked: “Wang Yun, a PhD from the School of Science in the School of Strip, introduced it, Escort In these battery systems, the calender is directly used as a negative, achieving a specific capacity of up to 1160 mAh g-1 and as low as -2.714 V (relative to standard hydrogen electrodes) oxidation and reduction power. The rich O2, thermostatic gas CO2, SO2 and single S can all be used as positive information to form various types of cord-metal batteries.
“In theory, these battery systems are respectively Sugar daddyAmbient O2, CO2, SO2 or solid S are used as positive active data; but in fact, positive data often needs to be loaded in porous carbon to be expressedWith higher electrochemical activity, these porous carbon substrates do not directly participate in electrochemical reactions, but act as loads of charge transfer media and activity data. “Wang Yun said that the low conductivity of positive data and discharge products is the first problem of its impact. “Even if a positive electrode with high conductivity is constructed, it is necessary to solve this problem on the surface, but it is worth noting that the different cord-metal batteries require different pore sizes and tracing to achieve better electrochemical functions. ”
In contrast, slow reaction force learning and higher overvoltage are also challenges every year. However, introducing catalyst energy is a fruitful way to improve positive reaction activity. In addition, reducing the size of the catalyst to nanoparticles, quantum points and even single atomic levels can get the cats that seem a bit discomfort at handover, and the two sounds are mourning. The most significant catalytic activity is in the middle.
Wang Yun told reporters that divergent battery systems respond to divergent catalysisManila escort demand.
For example, in Na-O2 system, the choice of catalyst can depend on its harmony with O2/O2- and its stable effect on the O2-middle at the electrode interface, such as expensive metal and transition metal oxides; in Na-CO2 battery system, only a double metal oxide has a certain catalytic effect, which can effectively promote the stable discharge product Na2CO3Escort manilaCatalytics that undergo reversible electrochemical reactions are still being found; in room temperature Na-S batteries, fantasy catalysts should have outstanding sulfur properties, so they can not only be combined with chemical keys to realize the fixation of polysulfides by Escort manila. escortactivity can also promote the dynamic learning process of the transformation between different sulfur species.
“The negative calcination limits the discharge capacity of the battery, and at the same time, the Escort manila‘s over-voltage power reduces the bank’s effectiveness during charging and discharging. On this side, we still need more basic research to remind negative reactionsProcess. In addition, the effective way to restrain the structure of dendrites and protect the highly reactive calcified electrodes are still to be explored. “Wang Yun said that the global consideration of electrolyte compatibility between positive and negative electrodes is also important. Today, the discussions on the relationship between metallogen and different positive electrodes are relatively independent, while the discussions on the whole battery are relatively lacking.
The long-term business development situation is not yet open, and it is refreshing
In addition to this broad negative electrode data problem, the differences in metallogen and metallogen batteries also have differencesSugar Baby‘s challenge has cast a shadow on its commercial applications.
Cao YuliangSugar babyIntroduction: For Na-O2 batteries, its reaction mechanism is still unclear. In order to obtain lower overvoltage and higher cyclic life, it is still to be studied to realize that Na-O2 is an important reaction product. In addition, the research on Na-CO2 batteries is still very unlimited, and its lower reaction is reversible and achieves achievement. The nature and poor circulation are still urgently needed to be solved. “Future research and discussions can focus on the positive atmosphere of CO2Sugar baby design and exploration of high-voltage electrolyte. ”
Based on the results of today’s research on Na-SO2 batteries, Cao Yuliang said that the application of NaAlCl4·2SO2 motorless electrolysis is mainly related to the long circulation, stability and safety of Na-SO2 batteries. The research can replace unstable stocksSugar Baby‘s negative data, reaction mechanisms such as the larger voltage removal during the charging and discharging process, the specific reaction paths during the charging process, the new organic electrolysis system, especially the gel and solid electrolysis quality. The development of Na-SO2 batteries are all p TC:
