How do you view the energy storage value of lithium iron phosphate batteries and the return of power lithium iron batteries? With BYD`s announcement that it will launch CTP lithium iron phosphate batteries (blade batteries), and claims that the volumetric energy density can be increased by 50%, iron-lithium batteries are back in front of everyone, and the entire market seems to be re-examining iron-lithium batteries.
With the announcement of SAIC, Wuling and other car companies that they will launch iron-lithium versions of passenger cars, and BYD has successively received 5G energy storage orders, it can be expected that the application prospects of lithium iron phosphate batteries in 2020 will be significantly better than in 2019. The market performance is indeed worth looking forward to.
1 How to view the energy storage value of lithium iron phosphate batteries
The iron-lithium battery energy storage system can be used as a buffer between a variety of power sources and stable power demand, and can increase the power generation capacity of unstable power sources such as wind energy and solar energy. The output power of wind power generation system oscillates due to the change of wind speed, and the energy storage system can provide stability and reactive power compensation for wind turbine output through the characteristics of fast response speed and almost equal charging and discharging cycle. At the same time, the energy storage system can adjust the voltage and control the system frequency in the off-grid power generation system.
The lithium iron phosphate battery energy storage system can be used to save the investment in fixed equipment of the grid system; improve the utilization of grid equipment, reduce financial risks, avoid huge one-time investments and extremely low equipment utilization, and use the investment for more Need and more important occasions; reduce the use cost of end users.
There are more than nine layers of pumped energy storage in my country's energy storage methods, but the proportion of electrochemical energy storage has been increasing in recent years. The 5G investment of the three major operators in 2020 has doubled compared to 2019. China Mobile's expected capital expenditure in 2020 is 179.8 billion yuan, of which 5G-related investment plans are about 100 billion yuan, compared with 24 billion yuan in 2019, a full five-fold increase this year. With the explosive construction of 5G base stations, it is expected that the demand for lithium iron phosphate batteries will increase substantially.
2 How do you view the return of power iron-lithium batteries? As the prices of major raw materials for iron-lithium batteries drop sharply, the cost-effectiveness of iron-lithium batteries is getting higher and higher. For large-scale production, the raw material cost of lithium iron phosphate batteries is less than 0.35 yuan/wh, and some companies can even achieve a better level. This is also the main reason why mainstream companies have dared to push the price of iron-lithium modules to 0.6-0.65 yuan/wh since 2020, which can be cheaper than ternary batteries by 0.15-0.2 yuan/wh. In the context of a price difference of 20%, it is not surprising that car companies have begun to choose to use lithium iron phosphate batteries.
In the early stage of the development of new energy vehicles, in order to be able to change the disadvantage of low battery life, major manufacturers have begun to develop batteries with higher energy density to obtain a longer battery life. Therefore, the ternary lithium battery with large capacity and high energy density has become the most used battery for new energy vehicles; at the same time, affected by the subsidy policy, the new energy vehicle subsidy has requirements for the long life of the car, and the ternary lithium battery can just meet With this requirement, ternary lithium batteries have gradually become the main force in the power battery market.
The reason why lithium iron phosphate batteries will be marginalized by the market is because of its low energy density, resulting in insufficient battery life. For a long time in the past, the power battery market was dominated by ternary lithium batteries. Now, with the advent of blade batteries, it is bound to break the existing power battery market pattern and usher in a new breakthrough. The release of the blade battery has brought the attention of users back to the lithium iron phosphate battery. Its high endurance and more safety advantages will lead a new outlet for power batteries.
The energy density technology of lithium iron phosphate batteries has been greatly improved. With the change in the trend of policy decline, lithium iron phosphate has gradually been favored by virtue of its own advantages of low cost, high safety, and long life. The pattern of "the rise of ternary and the decline of lithium iron" may be broken. This is also a major change for the power battery market. As the demand for lithium iron phosphate batteries continues to increase, the future lithium iron phosphate battery market may be broken. There is a substantial increase.
