Study a stock must first from the industry's outlook of the stock, not afraid of loss, in the sight of the fear of the future have no future.

English for the Cobalt, Cobalt, chemical symbol for Co, atomic number 27, after the iron (26), nickel (28), copper (29).Cobalt is silver, hardness higher than that of iron, ductile better than iron, magnetic weaker than iron.

Belongs to a small metal cobalt, it is very scarce, known as the "industrial monosodium glutamate" and "industrial teeth," said, is one of the important strategic photos, the most common used in production of high temperature alloy, heat resistance and corrosion alloy, especially in the military industry manufacture penetrator and protective armor, has an irreplaceable role in aircraft engine, as a result, the United States, Russia and China are included in the strategic reserve.

Civil rechargeable battery industry is the biggest use of ai. Cobalt accounted for 60% by weight of the cobalt acid lithium ion battery cathode material, and the anode material is decisive lithium ion battery performance, determine the battery rechargeable capacity and open circuit voltage of the main is to rely on the anode materials - cobalt acid lithium.

The world's main production of high performance cobalt acid lithium, cobalt oxide materials enterprises with Belgium belgium-based materials group Umicore SEIMEI company, OMG companies in the United States and Japan. We found that Huayou cobalt industry including an original shareholders: between China and Belgium direct equity investment fund, the Belgians has long been bullish on China's largest cobalt products manufacturing enterprises.

30% of the current global cobalt consumption in lithium-ion battery industry.

Cobalt acid lithium preparation:

1, from used to extract cobalt, nickel, cobalt, copper and cobalt ore minerals. This step is a subsidiary of CDM Huayou cobalt industry company in Dr Congo, after the primary cobalt ore to the sea from Dr Congo back to Ningbo port in China, then transport to Tongxiang city Zhejiang province.

2, with primary cobalt ore as raw material, producing high purity cobalt salt solution;

3, under the weak oxidizing atmosphere, the concentration of 40 ~ 70 g/l of high purity cobalt salt solution and the concentration of 60 ~ 200 g/l precipitant mixed reaction, the reaction temperature of 40 ~ 80 degrees Celsius, the reaction time is 5 ~ 60 minutes, filtering, washing, dry battery grade cobalt salt;

4, under the weak oxidizing atmosphere, 400 ~ 830 degrees Celsius calcined battery grade cobalt salt, 2 ~ 7 hours, the crushing system of micron or nanometer level of the cobalt oxide. Company's main products came out.

Cobalt few independent deposit, all is the associated elements from other deposit, nickel, copper, as the major minerals. Proven global output of 13 million tons, the gold of 5 million tons, China only 700000 tons, so master the head of the Dr Congo cobalt mineral is caught.

Cobalt acid lithium is the advantage of high working voltage, charge and discharge voltage stability, is suitable for large current charge and discharge, good circulation, the biggest drawback is expensive, your lack of cobalt in photos, the price is high, even historically low cobalt price over the past few years, but compared with manganese acid lithium, lithium phosphate still belongs to the noble.

And activity of pure cobalt acid lithium can pose a safety hazard in the process of use, which is before a few years companies have abandoned the cobalt acid lithium and selection of the main causes of lithium phosphate, BYD's choice is to lithium iron phosphate.

But the technology of the ceiling of the lithium iron phosphate is charging capacity cannot increase, and the instability of cobalt acid lithium people take solution on ternary material, nickel cobalt manganese acid lithium battery was born, with relatively cheap nickel and manganese replace more than 60% in cobalt acid lithium cobalt, cost advantage is very obvious. So a ratio at the same time, greatly improve the stability, almost the same as the lithium iron phosphate.

Charging capacity increasing, providing security, common price, that would make batteries ternary material unstoppable become the main power battery, tesla, BYD and other major manufacturers are choice.

At present, power lithium battery technical route is the lithium iron phosphate, three yuan (nickel, cobalt, manganese) material of lithium battery, the former advantage is stable, safe, the disadvantage is that large volume, less charge capacity, under the same unit, just run 150 kilometers, the lithium iron phosphate ternary material can run more than 400 kilometers.

To do this, you can enlarge the volume lithium iron phosphate battery buses using the former technology, the latter three yuan battery technology used on the ordinary cars, as the ternary material stability, security, gradually improve, more and more manufacturers will use three yuan battery, which is the guarantee of cobalt will surge in demand in the future.

As people demand to run farther and pure electric vehicles, batteries ternary material conquer security after taken aboard the leading position. This is what we now watch the cobalt price is at the bottom, the future will be the outbreak of the heart.

Many people worry cobalt in batteries ternary material proportion dropped sharply, than cobalt acid lithium batteries cobalt content difference is too big, so the cobalt price won't grow along with the new energy vehicles and benefit.

This is a meager profit but high turnover principle. Your original cobalt acid lithium death, no one to use, but weak demand, even if the cobalt content is high, can't sell, so the price of cobalt has been hovering at the bottom of the.

Now new technological breakthroughs, and safe and cheap batteries ternary material used in great quantities, although the monomer cobalt usage reduced, but the overall demand, as well as make cobalt demand growth, adding cobalt photos itself is precious, the original that a large proportion of cobalt acid lithium battery is difficult to meet the demand of human for a long time.

Earth's proven reserves of cobalt was 13 million tons, 700000 tons of local Chinese, about 1 million tons, in Dr Congo Chinese companies control Huayou accounted for 10%, about 100000 tons, this will increase to raise is directly improve more than 50000 tons!

You say: worse than the day his Lithium Huayou cobalt industry? Now Huayou at home as long as technology research and development, push forwards the cobalt oxide is the next

Step 5: the crush of micron or nanometer level lithium carbonate and micron or nanoscale the cobalt oxide by Moore mixture ratio, under weak oxygen atmosphere, with 450 ~ 950 degrees Celsius calcined 10 ~ 20 hours, crushing, grading is to produce cobalt acid lithium.

This step technology is in the hands of Belgium, the United States, Japan, and later made of cobalt acid lithium battery is three yuan sky Lithium, Jiangxi Feng Lithium, hundred million weft lithium can do, because the sky Lithium master lithium in Australia so it also is the highest, in the current share price is the same truth, Huayou is mastering the upstream photos, as long as the downstream extension technology, so the share price to one hundred yuan will be far behind?

So invest in stocks to studying technology development direction and the market demand direction, will be able to dig out the biggest dark horse!
