According to the information obtained from the relevant channels, March 3, Xiaopeng P7 will release the latest entry model, which is equipped with lithium iron phosphate battery version, in fact, this car has already been in early February. Disclosed related information, before the Spring Festival holiday, the 341nd catalog of the Ministry of Industry and Information Technology announced the first time Xiaopeng P7’s phosphate of Lithium Iron.

[123 ] Xiaopeng P7 phosphate lithium version declaration details
As for the last price, after May 3 officially released, we can know that this phosphate version of the lithium phosphate version of P7 can sell more cheap.
In addition to Xiaopeng, Feirtra also broke the important news related to the iron phosphate in February, Mask said on February 26, all the standard battery life models of Model 3 will be replaced. Lithium iron phosphate battery.
Twitter netizen: This is why you want to dig ourselves, right? They provide enough battery raw materials to meet Tesla’s needs.
Musk: Nickel is the biggest problem of current lithium battery capacity, so we have begun to put standard life-fired tin lithium batteries, super multi-iron lithium batteries!
Musk: This is not a problem that is losing, and our current capacity is limited. We are working hard to produce batteries to supplement the supplier’s capacity gap. Although suppliers have been fully increased, it is still unable to produce sufficient battery cells.
Xiaopeng, Tesla has added lithium iron phosphate, which can be said to have continued the trend of the 100-year-old lithium iron phosphate. In 2020, the growth rate of lithium iron phosphate batteries opened at least one body, the Chinese market for the whole year, three yuan lithium battery total car 38.9GWH, accounting for 61.1%, down 4.1%; phosphate The iron lithium battery is installed 24.4GWH, accounting for 38.3 percentage, accumulated by 20.6 percentage.

So today, the teacher will come to the Bangyu why is the lithium phosphate? What are the benefits and troubles from the life of the lithium iron phosphate?
Cheap is the first original power
Lithium iron phosphate compared to three yuan lithium at cost with unable to shake the advantages. And from 2020, this advantage is still expanding. Although the cost of the raw material for iron phosphate has been rapidly rising, but the price increase of the raw materials of the three-lithium is compared to the gap between the green tip car and the high-speed rail.
According to the website data of the business agency, lithium iron phosphate prices from December 2020 to now, rising from 36,000 yuan to 43,000 yuan per ton. Nearly 20%. The price of metal nickel rose from 124,000 yuan per ton to 140,000 yuan, the increase of 13%, the price of metal cobalt rose from 26.5-270,000 yuan per ton to 400,000 yuan, over 48%.
This comparison, although lithium iron phosphate causes rapid rise in the price of the raw material in the past year, but it is really not enough to look at the growth of the three-yuan lithium material.
- It is precisely because of the huge cost advantage of lithium iron phosphate batteries, since subsidies began to overlap, high-energy density three-dimensional lithium batteries have gradually lost subsidy advantages, The anti-attack on the iron phosphate has continued until now.
For ordinary consumers, the most direct impact of the cost of cost is the price reduction, MODEL 3 drops to 250,000, Xiaopeng P7 is aimed at 200,000, these must worship the low cost of phosphate. Give. Including the low-cost electric micrometer in the wind, also is also closely related to the cost advantage of lithium iron phosphate batteries. Although this battery has many problems, it is cheap is king!
Is there anything else?
The cheapness is undoubtedly the primary reason for this cyclic phosphate anti-attack tide, and the second cause is that the production capacity of the three-dimensional lithium battery is serious, and the inquiishing is more intensified. In addition to demand, in terms of three-yuan materials, metal nickel, cobalt has a serious supply crisis.
Pure cobalt powder
cobalt belongs to the nervous metallic metal of all year round, nearly half of the reserves and more than 70% of the reduction One of the most turbulent countries in Africa – Congo, so the supply situation of this metal material is imicole, and its cobalt is a rare metal, and the global total reserves are less than 8 million tons.
Nickel, metal friends will not be too unfamiliar, because nickel anti-corrosion characteristics, the coins in money in many countries are nickel, including RMB. The reserves of nickel metal are not small, which can be seen from the above less exaggerated prices, but in the face of the surge in three yuan lithium battery, the situation in short supply in the next few years will not be alleviated, only It will become solemn, and the out of stock will become normal.
So, now the main plant hugs lithium iron phosphate, except for the cost advantage, the stability of supply is also a major advantage, after all, lithium iron phosphate This material is not thin, the production supply is relatively smooth, although the short-term supply and demand tension can cause price fluctuations, but the possibility of timely supply issues is very low.For the current automakers, it is necessary to ensure that the stability of the supply chain is more sensitive than cost. If the line is forced to stop working, the loss will be an astronomical figure.
Is the lithium iron phosphate battery be used?
This is probably the most concerned thing about consumers. After all, the cost of the cost will bring price reduction, and the delivery capacity will bring timely benefits, that is always May only have the benefits there is no harm, we all know that the lithium iron phosphate energy is low, the endless capacity is weak, and the low temperature can be solved now? If you don’t solve it, so many lithium iron-lithium electric vehicles are not adding to consumers.
In fact, it is true that the highest energy density of lithium iron phosphate battery is the new battery just released at the end of 2020, 2020. , The energy density is 210Wh / kg, and the number of the three-dimensional lithium approaches 300 is completely insufficient. In terms of low temperature performance, lithium phosphate is insufficient. This flaw is the material decision, if it is solved, unless the material characteristics are changed, but this is not lithium iron phosphate.
Of course, caurists are not any way, and for energy density and battery strength, whether the higher density battery is still the development of no module technology, the lithium iron phosphate battery pack The energy density reaches the level close to the ternary lithium. Now use of lithium iron phosphate batteries, although life is indeed slightly weak, it is already possible to meet the basic needs.
The fifteenth season of 2020, the Han EV endless achievements of lithium iron phosphate battery
butIf the single travel distance is short, the time is short, the performance attenuation of the lithium phosphate battery is indeed very obvious, and each battery is still not hot, stopping, then stopping a few hours, continue to repeat There is no cycle that is stopped and stopped. This kind of working condition is indeed possible to have a possibility of ending half price.
In fact, this long-distance traveling condition for this interval time is the worst condition for any means of transport, because whether it is an internal combustion engine or a ternary lithium battery, it takes a certain working time to enter the best state. The internal combustion engine requires a heat engine, and the three-dimensional lithium also needs to heat the battery, so this pot cannot be completely built on the lithium iron phosphate.
State Review
In fact, the most fundamental cause of the lithium iron phosphate battery is still in money, manufacturers cost, users Wallet, in fact, each of us knows that the low temperature performance of lithium iron phosphate is difficult to cure, but as long as the price is in place, then there is no more chat. In short words: it is cheap, this is old, but also bike!
