The history of the ion battery can be traced back to the end of the year. The girl wrapped the cat with a towel and put it into the cap, and practiced the first commercial ion battery released by Sony in 1991. Before that, the Li/MoS2 battery released by Moli Energy dominated the whole country due to its energy density. However, due to the design shortcomings, many fire incidents occurred, so it had to undergo a large-scale recall, which eventually led to the slump of Moli Energy. At that time, Sony was also trying to develop a Li/MnO2 battery, but due to the shortcomings of Li metal itself, this technical plan was destined to fail. At that time, Sony was not only engaged in Li metal research and development, but the top international research and development teams such as the Exxon Group (Li/TiS2) and Bell Laboratory (Li/NbSe3) were all carrying out the development of steel metallic battery, but they all failed in the safety of Li metallic safety problems.

The reason why the steel metal negative can attract so much attention is precisely because of its high specific capacity (3860mAh/g), its excellent conductivity and low potential (-3.04V vs standard hydrogen electrodes and other advantages, if the steel metal negative electrode is applied to the primary battery, it is indeed a good negative electrode data, but if it is applied to the secondary battery, its shortcomings will be leaked, and the growing Li dendrites will not only form electrode expansion, but also have low efficacy. In severe cases, Li dendrites may even pierce the partitions between the negatives, causing short circuits between the negatives. Therefore, the late-developed Li metal negative batteries often suddenly explode when they cannot be predicted, like a fixed-time blowout that does not show time.
Because Li metal has a difficult problem of fighting at that time, Yoshino Akira, who was working in Asahi Kasei, turned his attention to graphite data and had a great disagreement with metallic steel. Li will have an intrusion reaction in the graphite negative situation. This prevents the natural birth of metallic Li and solves the problem of Li dendrites’ growth. However, the application of graphite data is not a big deal. When embedded in Li+, graphite data will also make the electrolyte dissolved unlike a wandering cat. “StoryThe molecules were embedded in the graphite together to form the graphite layer. Therefore, the study of graphite data in late Belipped experiments was not successful. Until Yoshino Akira, Fong, Von Sacken, Dahn and others discovered that low-temperature graphite (such as petroleum coke) could well restrain this co-embedding. baby has laid the foundation for the development of modern steel ion batteries, but because Yoshino Akira published related patents earlier and adopted a system closer to the current steel ion batteries, it is widely regarded as Yoshino Akira as the father of steel ion batteries. In this creative patent of Yoshino Akira, he used low-temperature graphite (petroleum coke) and LiCoO2 data (slightly processed) developed by the Silicon Electrode Master Goodenough in Oxford. The Manila escort was officially born in the modern Silicon Ion Baby. Since Li+ reacts in the negative, the steel ion battery is also called a “chair-type” battery. The concept of “chair-type” battery was first proposed by Armand and others in the 1970s of the last century. By embedding and repelling the positive negative information between the potential differences, Li+ realized energy. In the late stage, there was no suitable positive negative information, so the battery voltage was mostly lower than 2V, which did not cause enough attention until Yoshino Akira opened up the high-voltage characteristic of Goodenough LiCManila The escortoO2 data is combined with low temperature graphite data, and this Sugar daddy battery design concept is truly revealed.
After Yoshino Akira published a related patent, Asahi Kasei established the A&T battery group to produce steel ion batteries. Today, A&T has become a subsidiary of Toshiba. Although Yoshino Akira has completed the development of the large-scale Sugar daddy‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialent‘s dialentSugar baby competed with the trendy horn and the newly invented horn batteries. At that time, Sony was the leader of the 3C consumer electronics field. In the late stage, it had developed Sugar daddy metal primary batteries. It began to turn to secondary batteries in 1985 and soon came from the last NiEscort manila-Cd battery has once again turned to a steel secondary battery. As a major consumer electronics industry, Sony has a strong desire to develop a new market that has never been seen before, which is also the main reason for Sony’s final victory.
In the late period, due to the ability of anti-solvents produced by low-temperature coke, it is not only because of its Sugar daddy has relatively low capacity and is still widely used in the first generation of steel ion batteries. In the second generation of steel ion batteries, low-temperature coke is replaced by hard carbon with higher capacity and better function. However, hard carbon still has many problems. Therefore, the medium-phase carbon microspheres (MCMB) that are widely used today have been used in the third generation of steel ion batteries.
In terms of positive data, Gooden LiCoO2 developed by Laozi is known as the most powerful positive data, and it is still widely used in the consumer electronics field. It was not until recent years that ternary data and phosphate steel materials have gradually replaced the traditional LiCoO2 data in the power battery field.
In terms of adhesives, the late PVDF has poor adhesive properties on the positive side, which has a certain impact on the steel ion batteries until Kureha Chemical Ind.Sugar daddy Co. introduced carboxylic anhydride into PVDF, which significantly improved the adhesion of PVDF in Al foil.
Although the outer shell of the galvanized ion battery is not eye-catching, the benefits of the galvanized ion battery still play a major role. Sony later believed that The presence of trace amounts of HF in the electrolyte is to choose stainless steel as the shell of the steel ion battery. However, the shell impedance of stainless steel was found in the application, so the solution plan for the iron shell was finally selected.
With Sony’s unremitting efforts, the first Escort manilaThe commercial steel ion battery was launched into the market in 1991.https://philippines-sugar.net/”>Sugar baby, Sony’s first-generation battery energy density is 200Wh/L and its component energy density is 80Wh/L (4.1V). After the second-generation steel ion battery uses hard carbon negative data, the battery’s Sugar baby‘s energy density was reduced to 295Wh/L and 120Wh/kg (4.2V), and the energy density of the third generation of steel ion batteries was reached 400W/L and 155Wh/kg, Sony Escort became the leader of the steel ion battery field at that time, but the fierce competition from other manufacturers caused Sony’s steel ion battery business to continue to shrink, and finally transferred the battery business to Murata’s Fujian Group.
Now, after 28 years of development, the steel ion battery is no longer limited to the traditional 3C consumer electronic field. We are nowSugar baby things, electric cars, etc. can all see the figure of the steel ion battery, and the size of the steel ion battery is no longer limited to 18650, and it has more sizes and structures. The most important change is that in the battery function, we use the traditional 18650 batterySugar daddy As an example, the energy-type 18650 battery released by Chaosong Infrastructure can have a capacity of more than 3.3Ah and an energy density of more than 240Wh/kg. Compared with the energy density of the first generation of electrolyte ion batteries, the energy density has already reached
