The brother above is right, it's about 8.5 yuan/AH. Our company produces it, but your 200AH is too scary, I wonder if there is an extra zero.< /p>

Tesla's "cobalt-free batteries", BYD's daily limit, the battery landscape is about to change

The current discharge of iron-lithium battery in 1C is unlikely to exceed 8 yuan /AH, 17% tax included. If it is a large current discharge battery, it is divided into 5C, 10-15C, and discharges within 20C. be more inconvenient depending on the budget of each household, not the same.

The polymer is actually a kind of process, that is, the electrolyte is a solid lithium battery, so it only needs to be classified into iron type and ternary lithium. There is no need to emphasize the polymer. I think it is better to charge and discharge iron lithium monomerum with low current, because the lithium iron monomer cycle laboratory data reached 8000 times capacity and 70% DOD. This is currently unmatched by ternary lithium cobalt oxide and lithium manganate. it's a combination, I think Sanyuan is good, but the consistency of iron-lithium batteries is too bad. This guy claims to be able to cycle up to 2000 times and 80% DOD. Few combinations can cross 800 times, and the. security is not necessarily safe. Just this year in Hangzhou An electric taxi in Shanghai burned down and a purely electric bus spontaneously combusted at the Shenzhen Universiade. Several purely electric buses are said to have also spontaneously combusted. batteries, which are not safe batteries. The ternary battery has a high capacity ratio, relatively good consistency, relatively cheap price, and can cycle up to 800-1000 times, which is good. Betterthan lithium iron.

A recent blockbuster news shocked the automotive market. Tesla will use cobalt-free batteries, and the lithium iron phosphate route is the first choice. Everyone knows that Tesla has two hearts: software and batteries. Today, its software development is moving forward on a seemingly smooth path, but when it comes to batteries, Tesla is considering a different path. Why did Tesla suddenly switch from ternary lithium batteries from Panasonic and LG to lithium iron phosphate batteries?

Compared with hot ternary lithium battery, the advantages of lithium iron acid battery include four points:

1. Better thermal stability, we have all seen it at Tesla. Many car models have it. has been repeatedly exposed to spontaneous combustion after collisions. The reason is that the thermal stability of the damaged battery is poor. Because ofCharacteristics of the chemical structure of lithium iron phosphate, it inherently has better thermal stability and is less likely to spontaneously ignite even if it collides and breaks. This is obviously a safer choice.

2. Long lifespan, the battery will only decompose to 80% of its original value after the number of full charge and discharge cycles is more than 3500 times, which has better durability. ;

3. High charging efficiency, 1.5C lithium iron phosphate battery generally can be fully charged within 40 minutes;

4. Low cost, the current average cost of lithium iron in the industry. phosphate batteries cost 0.65 yuan/Wh, about a quarter cheaper than 0.85 yuan/Wh for ternary lithium batteries.

With these four major advantages, lithium iron phosphate is still the leading role of ternary lithium. What is the reason ? VS'is because energy density cannot compete with the latter.

In 2015, the single energy density of lithium iron phosphate battery was 120 Wh/kg, and the energy density after bundling was 80 Wh/kg, which is the same as the energy density of 180 Wh/kg and 110 Wh. /kg after grouping. Yuan lithium batteries are not of the same order of magnitude, and their cruising range is far from comparable to ternary lithium batteries.

This year, the State Council issued "Made in China 2025", setting the development target of electric battery systems as "the specific energy of a battery cell reaches more than 400 Wh/kg”. the subsidy policy for new energy vehicles Energy density and battery cruising range are the main indicators, which will lead new energy vehicle enterprises seeking high subsidies toabandon the lithium iron phosphate route and move to ternary lithium.

The subsidy policy has therefore enabled ternary lithium batteries with higher battery density and longer cycle life to play a leading role.

The opportunity for a lithium iron phosphate counterattack has arisen

The subsidy was cut in half in July 2019, and the subsidy will be completely canceled by 'future, and the halo of ternary lithium batteries gradually diminishes. The opportunity for lithium iron phosphate to strike back has presented itself.

From July, that is, after subsidies for new energy vehicles were cut in half, the demand for ternary lithium batteries began to decline and the performance all throughout the second half were weak.

The two advantages of good safety performance and low cost haveencouraged new energy vehicle manufacturers to once again turn their attention to lithium iron phosphate. Tesla is cooperating with CATL to use cobalt-free batteries. The main reason is that Tesla, which sells higher prices, wants to further reduce costs and enter the low-end market.

There is another important reason for the return of lithium iron phosphate: it is a major technological advance.

BYD's latest lithium iron phosphate "blade battery", which is about to be mass produced, uses a flat battery cell design. Compared with traditional lithium iron batteries, the energy density can be increased by 50%, and the vehicle battery life can also reach 8 more than 1.2 million kilometers per year.

BYD boss Wang Chuanfu also said that BYD plans to increase its single energy density to180 Wh/kg and the system energy density to 160 Wh/kg in the next two years, which is the same as the ternary lithium level. Batteries almost the same.

According to the latest new energy promotion catalog released by the Ministry of Industry and Information Technology, the first BYD Han EV pure electric model equipped with a “blade battery” has a Maximum NEDC operating range of up to 605 km/h. kilometers, which is equivalent to the current longest-lasting ternary lithium battery in battery electric vehicles (650 km) are very close.

In addition, the production costs of BYD's battery units will also decrease by 30%.

The shortcomings in energy density have been addressed and the cost advantage has been further emphasized. Lithium iron phosphate batteries have another opportunity to make a big impact. Yesterday's daily limit of BYD and associated stocksciées further confirmed that the battery landscape is about to change dramatically. At the same time, it also makes people look forward to the BYD Han equipped with blade batteries, which will be launched in June.
