In 1991, after six years of screening of 100 million data plans, the first steel ion battery for the consumer market was officially pushed to the forefront by Sony.
In the blink of an eye, in the past thirty years, the ionic batteries have entered every aspect of our lives from birth to maturity. But with the emergence of technical bottlenecks, this round-rotation battery technology cycle is about to reach the stage of iteration. In the past six months, the continuous surge of battery technologies and data systems such as non-coat batteries, quad-cell batteries, solid-state batteries and other battery technologies and data systems have shown that a new wave of transformation in battery industry is approaching.
The difference between the backward wheel battery focus technology is that the cycle of this wheel battery technology iteration is in conjunction with the tide of the development of new power vehicles, making the technology and data systems more suitable for power batteries aboard the round table discussed in the industry and academic circles. Since the birth of the battery, no special battery has been valued since the beginning of this product, and the request for high energy density, strong safety and stability of power batteries has also made the purpose of battery development in the next decade to be reliable.
Standing at the end of the 8-Series ternary steel batteries and phosphate steel batteries era, we look forward to the ability of non-scaling batteries, solid-state batteries, ionic batteries, sulfide batteries, galvanized air batteries, and even fuel batteries to become the mainstream technological routes of future power batteries. Between them, they are both Sugar daddy has a relationship of competing with each other, and a relationship of Sugar baby‘s route.
We may not be able to determine which or which technical routes will definitely become the bond of the future power battery market, but it can be determined that the battery technology that has entered the historical stage during this period will have a profound impact on the power battery and its related industries in the next decade, or even longer.
[·Five focal reactions The tide of the steel battery station·]
In the 150 years from 1870 to the present, the battery industry has experienced five focal technical reactions, and the mainstream technology paths of the entire industry have also transitioned from acid batteries, focal batteries, focal batteries, and focal batteries to focal ion batteries.
In today’s battery market, the steel circuit has become a unique technical circuit. In 2019, the steel ion battery market accounted for nearly 90% of the global electrochemical energy storage machines, and the steel battery and sulfur storage battery.The market share of the pool is only left.
In particular, the 8-series ternary steel battery represented by NCM811Sugar daddy and NCA811 have become the most important power battery system in the current industry. With the emergence of technologies such as blade batteries and CTP battery packs, the phosphate steel battery system also ushered in a small flight in the first half of this year.
Although the passenger car capacity is used, the three-yuan steel battery still realizes the advantages of crushing with high energy density, under the hype of the media and manufacturers, the phosphate iron steel seems to have a great energy to survive and the three-yuan steel for another 300 rounds.
But in fact we all know that this is impossible. The focal difference between the ternary (parameters|picture) steel battery and Sugar daddyphosphate iron steel battery is in terms of energy density. Even if the blade battery powered by Biadi reaches 140Wh/kg, it can reach 160-170Wh/kg at the maximum limit, but Panasonic released it for NCA811 ternary steel on Tesla Model 3 (parameters|pictures)Pinay The single energy density of the escort battery has reached 340Wh/kg, more than twice that of the top-notch phosphate iron electrolyte batteries.
The difference between the two even makes the circulatory function of the phosphate iron-silica system stronger than the ternary steel system. High energy density means that in a single charge and discharge cycle, more electricity can be stored, thereby reducing the charge and discharge cycle required by the battery during the nearby life cycle. This feature makes the ternary steel battery still guarantee less battery life reduction in the current ternary steel battery when the circulation function is not as good as the phosphate steel steel. This is also the reason why the ternary steel battery installed at present is far more than the phosphate steel steel steel.
However, it is clear that the phosphate steel battery has not been cut off due to its functional disadvantages. In 2019, this type of battery still achieved 19.98GWh of installations in the domestic vehicle power battery market, accounting for 32%. A large number of new power passenger cars, new power commercial cars, and even some passenger cars with shorter mileage options to apply this type of battery. The characteristic of these models is that the energy density of the power battery is not high, and the safety and stability are more important.
The three-way steel battery is a sluggish little guy found in the branches in the passenger car market today. The mainstream choices include SAIC, Guangqi, BAIC, Jixiang, ChangChina, Daimler, Majority, General Motors, Tesla and other domestic and foreign vehicles have applied ternary steel batteries on their new power models. NEDC’s continuous flights of more than 600 kilometers have all applied 8-Series ternary steel batteries.
This is also the current market situation today. Both ternary steel batteries and phosphate steel batteries have corresponding application scenarios. In the short term, neither technical route will completely dissipate.
But this current situation will inevitably not be extended for a long time. Behind the demand for both ternary steel batteries and phosphate steel batteries is that both technical routes cannot fully meet the needs of the industry.
For ternary steel batteries, the self-ignition change of electric vehicles in recent years has caused its safety and safety precautions, and the energy density it relies on is no longer difficult to achieve. Based on the current positive electrode data system, even if the graphite electrode is replaced by silicon-based alloy, the lower limit of the single energy density of the ternary steel batteries is only 300-350Wh/kg, which is surprising and the safety is completely uncontrollable.
For phosphate steel batteries, their functions have become close to the limit in terms of chemical systems. Companies such as Biadi and China Automotive Technology, which have developed long-term iron and steel phosphate systems, cannot make more improvements to them in their data. Turning forward, we seek breakthroughs in battery packaging and production technology.
It is easy to see that the current ternary and phosphate steel systems have reached the ceiling in terms of technological evolution, and the market is still waiting for the emergence of Sugar daddy to wait for the emergence of advanced power batteries.
[·2020-2025: Solid battery is maturing, and battery growth is inevitable·]
So, what is the next generation of power batteries?
In the reality of the existing ternary steel battery, things are indeed like the dream of the beekeeper failure of Ye Qiuguan, which is a problem exposed by the phosphate steel battery system. The energy density, safety, stability, and capital problems are all problems that need to be solved by the next generation of power batteries. The solution proposed for surrounding these problems is undoubtedly the key technical route in the past five years.
The most noteworthy next-generation battery system that is free of charge is the battery.
Licently, it is understood that the non-glass battery covers all batteries that do not include the bulb elements in the data system.The products include not only steel ionic batteries such as iron phosphate, spinel phosphate, spinel phosphate, spinel phosphate, spinel phosphate, and spinel phosphate, but also include the first generation of battery systems such as oxidation batteries and pentactic acid batteries.
But there are two plans for the real hope of becoming the next generation battery system, spinel oxidine and high-poly oxidine.
The former is a data system developed based on the low-capacity data spinel acid dielectric. It has a reversible capacity of 146.7mAh/g, a voltage platform of 4.7V, and is highly stable and excellent. This data system is characterized by weak energy density, but the charging and discharging power is large, which is suitable for instant power output.
