The domestic NCA layout has made great progress.

According to the ministry of industry and the request of "auto industry long-term development planning, power battery monomer energy density in 2020 to 300 wh/kg, it become the lithium electricity industry efforts to one of the goals of the research.

And domestic battery enterprise at present the mainstream of the materials used, such as NCM111, NCM523, etc., have been unable to meet the requirements of higher range, encourage domestic enterprises to a higher specific capacity of battery material layout.In order to meet the requirements of the energy density, and perfect to avoid price peak, each big enterprise scrambled into high nickel lithium-ion batteries ternary system of research and development.

The obvious advantages of high nickel ternary and high nickel ternary with sliding and NCA two routes.According to the starting point for research (SPIR) data statistics, in 2017 the NCAThe ternary battery installed capacity of 286.5 MWh, up 229% from a year earlier, in 2016 more than three times the 87 MWh.

Although the NCA ternary battery such a high growth rate, and new energy car giant tesla also chose the NCA of Panasonic battery, but domestic battery manufacturers and car companies have more choice the development route of sliding, really amazing.

To this end, lithium rtvu data journalists do the following analysis:

The relative merits of NCA and sliding?

At present, high nickel ternary material is one of the most able to save costs at the same time, improve the ternary cathode material specific capacity, and meet the requirements of high energy density batteries battery materials.At present, the domestic mainstream route is sliding, which NCM622 and NCM811 system material, the energy density can reach 230 wh/kg and 280 wh/kg, () the link can be to understand the details of high nickel NCM811 progress.

NCM811 progress now in full swing and mass production, let a person can't help but think of as high nickel ternary material of NCA.Although temporary countless according to contrast the relative merits of NCA and sliding material, but also has the advantage NCA material has "forgotten" by domestic enterprises.

Zhihu on one net friend explained: "NCA poor stability, although the domestic production of NCA conditions, but the overall use of the technology is still immature."

Actually on the technical route, production process and conditions of the NCA material than sliding more demanding.The difficulty lies in the production process, the preparation of precursor and roasting process, a high requirement on the related equipment.And equipment very strict requirements, and comes with the increase of cost.NCA high nickel material alkali is higher at the same time, need to pure oxygen, humidity control under 10%, there is no doubt that add a lot of difficulty and capital investment, the domestic enterprises form a big challenge.

Money means increased costs, new energy vehicles which power battery occupies nearly half of the cost.This alone, it is difficult to let people welcome.

, "said Dr Industry some battery enterprise NCA I think it's very suitable power battery for passenger cars, but Chinese companies must now close and patent clearance material, process, difficulty is larger.At present, each enterprise has certain layout, to expand when market is difficult to judge."

Few companies selected NCA, why the route "forgotten"

Academician Chen said: "the more the key reason is that may be Chinese car companies want to use, but not necessarily be harnessed.Tesla's vehicle design and battery systems and control ability is not most of the Chinese car companies in the short term can imitate and beyond."

Look from the current situation of the global new energy vehicles, can give full play to the NCA batteries, car companies, three yuan is the Tesla.Tesla's vehicle design and battery system management control technology, can effectively avoid thermal runaway induced by high energy density.

China as the world's largest new energy automobile production and consumer, domestic enterprises in order to meet the needs of the makers of lithium-ion batteries, also in the development of high capacity battery.Such as can zhuo, lishen, bick successively to NCA development phase of the battery.

In fact, in the same selection conforms to the requirements of power battery, NCA batteries due to its particularity, also want to merit "choose" forms, and can use the NCA battery domestic automakers are numbered.

By Tesla pet NCA, therefore, high nickel batteries, three yuan is not who can be loved.Also don't know, when Chinese NCA materials market?

Development of NCA in China?

Due to the high technical barriers of NCA materials, at present, the production is less, production enterprise mainly concentrated in Japan and South Korea.As early as in 2016, Japan and South Korea NCA output reached 26800 tons of the two countries.And until 2018, our country enterprise almost in r&d or small-scale pilot phase.Some battery enterprises progress is as follows:

Can DE lang in 2017 production the NCA batteries

It is reported, Shanghai can DE lang has been developed and used large quantities of 3.2 the NCA Ah batteries, and the energy density of 250 wh/kg.This product is not only very high consistency, and good performance.In 2017 shipments of more than 300 MWH, mainly supporting dongfeng and xiao peng car passenger car.

Day peng power had baojun E200 models supply power

The Macao peng power lithium battery subsidiary below the shun Cheong days have independent research and development and production of NCA system battery, system energy density of 160 wh/kg, in a total capacity of up to 3 GWH, there are 2 GWH production NCA and NCM811 high nickel cylindrical cells.

External publicity recently, day peng power will for Wuling Baojun E200 model supporting NCA battery.At the same time, the day peng power will speed up NCA21700 series batteries, 2 GWH will also increases production at the end of the year, and plans to continue to expand produces 2019 GWH 3.

Research and development of Tianjin lishen NCA batteries energy density of more than 300 wh/kg

It is understood that in Tianjin lishen battery Co., LTD., research and development of NCA ternary high specific energy power lithium battery energy density, monomer 302 wh/Kg, the volume energy density is greater than 642 wh/L, 1 c recharge cycles under 25 ℃ 710 times (100% DOD), capacity to maintain rate of 80%;The current loop 285 times (100% DOD) capacity retention rate is as high as 96%.To develop specific energy 300 wh/kg, the cycle life of 1500 timesLithium ion batteriesMonomer laid a foundation.

The lion technology investment construction NCA ternary precursor battery cathode material

Last December 29, the lion is a wholly owned subsidiary of science and technology of fujian new energy and fierce lion yicheng city people's government signed the "about investing in NCA ternary precursor battery cathode material project contract, the lion of fujian in yicheng ray large industrial park total investment is RMB 200 million yuan, the construction of NCA ternary precursor battery cathode material project.

Other enterprises

The CATL in terms of NCA ternary lithium electricity has the rich technical reserves;Great energy has production NCA batteries used in consumer digital domain, NCA battery powered in development;Byd NCA high nickel ternary layout, predict to be finished within two years, can continue to use the existing production line;When science and technology full of model such as new production line can produce NCA dynamic multiple material...

In addition to battery enterprises, domestic existing part of the material research and development of enterprises and production NCA.

Foreign enterprises in production of NCA materials are: Japan's sumitomo metal industries, Japan chemical industry co., LTD and household chemical;South Korea Ecopro and GSEM etc. Several well-known materials enterprises.And domestic also have Mr Terry, shanshan energy, let the lithium electricity, the mo, long-term well-known materials such as enterprise, spread the news of NCA materials.

Shanshan shares of ningxia in the positive project phase ii planning capacity of 7200 tons, three yuan, can produce high NCA nickel anode materials and is the product has landed tesla and Panasonic;Mr Terry NCA capacity is about 3000 tons/year, have been implemented to Panasonic and other customer sales.

Conclusion:

Recently, Panasonic, Samsung, and Jinsha river capital acquisition AESC factory in China, the enterprise has the NCA battery capacity, cooperating with domestic companies, help to promote domestic NCA materials production, the application level.

Although domestic NCA started late, the technical level more foreign companies have a large gap, but the starting point for research (SPIR) to predict the future three years NCA materials market demand growth will render multiple.

Now, with large-scale production of NCA enterprises have online, NCA battery mass production and formally to the market day still far?
