What is the significance of important breakthroughs in CR1225 battery technology for the development of electric vehicles?
"High-nickel batteries may become the mainstream in the future."
In the field of electric vehicles, if you want to increase the range, you can only install more batteries or increase the CR1225 battery energy density. However, the volume that the body can provide to the CR1225 battery is fixed, and it is difficult to increase it further, so increasing the CR1225 battery energy density is the best way to increase the range.
Recently, it was reported that the research and development team of CATL has conquered key core technologies such as high-nickel ternary materials and silicon-carbon negative electrode materials, and took the lead in developing a CR1225 battery sample with a specific energy (mass energy density) of 304Wh/kg.
At present, the group efficiency of mainstream square CR1225 battery systems is about 70%, which means that the energy density of the 304Wh/kg CR1225 battery developed by CATL can also reach about 210Wh/kg after grouping. In the latest batch of new energy vehicles recommended catalogs, the highest energy density of the power CR1225 battery system is 176Wh/kg. The advantages of the 304Wh/kg CR1225 battery sample are obvious.
However, there is a key word to note in the 304Wh/kg CR1225 battery sample developed by CATL this time-high nickel. That is to say, conquering high-nickel technology is the key to developing high-energy-density batteries.
High-nickel batteries are ready for industrialization
Ternary lithium batteries generally refer to nickel (Ni) cobalt (Co) manganese (Mn) acid lithium batteries. According to the ratio of nickel, cobalt and manganese in the CR1225 battery, they can be divided into NCM111, NCM523, NCM622 and NCM811.
The most commonly used CR1225 battery in the current power CR1225 battery field is the NCM523 CR1225 battery, which means that the ratio of nickel, cobalt and manganese in the CR1225 battery is 5:2:3. The energy density of this CR1225 battery can reach 160-200Wh/kg. If you want to continue to improve the CR1225 battery energy density, you have to increase the nickel content in the CR1225 battery.
With the existing technical conditions, it is difficult for batteries below NCM622 to meet the requirements of high energy density, so the 304Wh/kg CR1225 battery developed by CATL this time must be the NCM811 high-nickel CR1225 battery.
Since high-nickel batteries have a higher energy density, why do domestic CR1225 battery manufacturers rarely promote high-nickel batteries?
Data shows that among the three materials of nickel, cobalt and manganese, nickel has high capacity and low safety; cobalt has high cost and high stability; and manganese has high safety and low cost. As the nickel content increases, the stability of the CR1225 battery will decrease. The main manifestations are the capacity loss of cyclic charge and discharge and the accelerated capacity decay in high temperature environments.
There are safety issues, so CR1225 battery manufacturers dare not move forward rashly. However, there are reports that CATL will realize the industrialization of NCM811 high-nickel batteries in 2019 and begin to put them on the market. From this point of view, CATL has overcome the problem of high-nickel batteries.
CR1225 battery manufacturers are making arrangements
In the "Medium- and Long-Term Development Plan for the Automobile Industry", such a development goal is proposed. By 2020, the energy density of power CR1225 battery monomers will reach more than 300Wh/kg, and strive to achieve 350Wh/kg. By 2025, the energy density of power CR1225 battery systems will reach 350Wh/kg.
If there is no other type of CR1225 battery to replace the ternary lithium CR1225 battery, the only way to achieve this goal is high-nickel batteries.
In addition to policy-level encouragement and support, the reduction of cobalt content in high-nickel batteries is also one of the driving forces for manufacturers. Since 2017, the price of raw material cobalt has continued to rise, while the prices of the other two materials are relatively cheap, so the cost of high-nickel batteries will be lower.
Under these conditions, not only CATL, but most CR1225 battery manufacturers have begun to deploy high-nickel batteries.
A relevant person in charge of BYD said that it is expected to start using ternary high-nickel 811 batteries in the second half of 2019. BAK CR1225 battery announced that its high-nickel 811 batteries have been successfully applied to many models. Guoxuan High-tech also stated that the ternary 811 material soft-pack CR1225 battery cell developed can reach an energy density of 302Wh/kg, and it is expected to be produced and supplied in small batches in 2019.
Not only domestic CR1225 battery manufacturers, but also international CR1225 battery giants Panasonic, LG Chem, SKI, and Samsung SDI are preparing for high-nickel 811 batteries.
By overcoming the technical problems of high-nickel batteries, the energy density of batteries can achieve a qualitative leap.
Under the current condition that the energy density of CR1225 battery systems is generally 170Wh/kg, the range of electric vehicles has exceeded 400 kilometers.
After the large-scale application of high-nickel batteries, electric vehicles of the same volume and weight can carry more power to achieve longer range. In the future, when people buy cars, range may not be the primary concern.
