Energy storage market trends, lithium battery still sing leading role
'in the past three years, the cost of lithium-ion battery energy storage system quickly fell by 50%, the second by 50% over the next three years also seems to be within reach.
With the rapid drop in energy storage costs, can expect the rapid growth of the electric vehicles and grid energy storage project, the rapid development of the energy storage industry is expected to become the power and energy on the basis of dynamic change.
'on April 11, energy storage industry technology alliance director Eric chen-hua yu in the latest release of the 2016 white paper on energy storage industry research (
Hereinafter referred to as: white paper)
In this note.
This year has been the industry of noble energy storage equipment, with new attitude to appear in front of the industry.
Li-ion battery technology ACTS as the leading role, the report said China's energy storage market from the point of view of technology distribution, in running the project, the application of energy storage technology mainly in lithium ion batteries, lead-acid batteries and flow battery, and lithium ion battery of the cumulative size proportion is the largest, accounts for two-thirds of the market in China.
Eric chen-hua yu to our reporter, said: 'as a decline in the cost of the development of power battery for energy storage.
'it is understood that domestic manufacturers develop energy storage projects focused on lithium ion batteries, lead-acid batteries, and flow battery technology manufacturers.
By the end of 2015, China's energy storage program installed in the size of the top 10 manufacturers, the number of lithium-ion battery manufacturers the most, there are six.
Among them, byd, silver long new energy companies is not only the domestic energy storage machine manufacturer, is also a lithium battery manufacturer, is pure electric car vehicle manufacturers.
Broadening the industry chain, earlier in the upstream of batteries battery material layout from a purely electric car market growth in dividends.
The personage inside course of study to our reporter, said: 'high degree of marketization of the auto industry to storage the survival and development of the enterprise provides the soil.
To achieve energy storage technology, reduced cost, need huge research and development funds.
Under the circumstances of price policy remains unclear, storage enterprises only relying on the car market, can realize the battery research core of competitiveness.
'in the electric vehicle market), energy storage enterprise again beautiful transcripts.
Recently, the China association of automobile manufacturers released figures showing that China's new energy vehicle production in April 31266, sales of 31722 units, year-on-year growth in 178.
3% and 190.
Of pure electric vehicle production completed 23918 and 23908, respectively, year-on-year growth in 227.
9% and 243.
From 2020, only four years, the country's 5 million new energy car ownership to open a blockbuster single power battery production, in other words will also provide battery technology breakthrough possible.
'from the point of view of distribution of energy storage technology, lithium ion battery technology mature, high specific energy, good stability, the price is relatively modest, installed high proportion, fast growth, through hair, transport, distribution, with each link.
'silver long hai-jun li, vice President of the automobile research institute said at the meeting.
Market appeared polarization trend of lithium ion battery large camps, including cobalt acid lithium, manganese acid lithium, lithium iron phosphate, lithium titanate, and other technical departments.
Whether applied to power battery or storage project, considering the safety of the battery, it should belong to the first.
Times the energy density, manganese acid lithium, lithium titanate, lithium iron phosphate technology into the first camp.
Eric chen-hua yu said: 'in the premise of security, high cost performance products will inevitably affect the choice of the technical route.
It is important to note that the security is still the qualitative indicators, the future energy storage applications deal with product safety quantitative indexes are put forward.
'as we have learned, silver long new energy and the southern power grid and countries' 863 project' demonstration projects of energy storage power station project 2 mw lithium titanate battery energy storage station in April 2015 by the Ministry of Science and Technology.
High security, 24000 -
The cycle life of 35000 times, 6 -
Ten minutes fast charging performance, 50 - below zero
60 degrees Celsius wide temperature environment where in lithium battery lithium titanate camp.
China electric power research institute DianGongSuo to well-off, director once said: 'lithium titanate performance advantages especially for the grid ratio performance requirements.
Large capacity storage system should promote long life, low cost of lithium titanate battery technology.
'white paper points out that by the end of 2020, to perfect the lithium ion battery materials research and development and preparation technology of various components, compete with the international level, the cycle life of up to 6000 -
Costs have fallen to 1000-8000 times, system
It is understood that the current lithium battery costs an average of 2000 -
3000 yuan/KWH, including 1500 - mainstream manufacturers system cost can be realized
2000 yuan/KWH, battery costs under 1000 yuan/KWH.
It was reported that zhuhai silver long new energy group, research and development of the fourth generation of lithium titanate battery, costs down as much as forty percent.
The fourth generation of high density than lithium titanate battery costs fell by 40%, the third generation product energy density increased by 30%.
So far, with the rapid development of the electric car market, battery manufacturing companies are expanding capacity, battery costs or to fall further.
Eric chen-hua yu stressed: 'energy storage market appeared polarization trend, a manufacturer's capacity is not enough, two types of manufacturer's overcapacity problem.
Enterprises should be combined with their own situation to adjust production capacity layout.
'lithium batteries and energy storage battery manufacturer, the product by the supervision and inspection institute of guangdong province, through international CE certification, by the ping an insurance company of China national group, a two-year warranty, the first in the New Year.
