How does lithium iron phosphate rise in ternary materials?

At present, domestic power battery mainly divided into two factions, depending on the cathode material is divided into pie and ternary lithium iron phosphate material sent.

How to lithium iron phosphate in ternary material rise, through their own channels?

The type and performance comparison of the anode material

The ternary material fire

From the point of production, the ternary material has become the anode material of the highest growth niche, according to statistics, in 2017 the national cathode material production is 210000 tons, an increase of 3, three yuan materials 86000 tons, 58000 tons of lithium iron phosphate, lithium cobalt acid 45000 tons, 21000 tons of manganese acid lithium, ternary material to replace 2016 became the highest growth rate in 2017 lithium iron phosphate anode materials, benefit passenger car passenger seat as important incremental new energy vehicles.

In 2017 the anode material production structure in our country

From the point of raw materials, since 2017, cobalt metal prices, cobalt ternary battery with cobalt become future demand for fastest growing space of the largest in the field. Ternary cathode material rose, in the face of rapidly rising cost pressure, battery manufacturers use the anode materials technology synergy to ternary cathode material layout, buffer raw materials rise in price shock, and grasp the upstream resources. Ternary material than lithium iron phosphate greater profit space, many enterprises have layout ternary material.

How to get through their meridians lithium iron phosphate?

1, technological breakthroughs, to solve the low energy density of shortcomings

lithium iron phosphate batteries, it is to point to use as the anode material of lithium iron phosphate lithium ion batteries. Ternary lithium battery materials refers to the use of nickel cobalt manganese acid lithium as the anode material, graphite as the cathode material of lithium battery.

Unlike the lithium iron phosphate, the ternary lithium battery high voltage platform, this also means that under the same volume or weight, ternary lithium battery than power, greater than power. In addition, in the big charge ratio, and low temperature resistance, etc., the ternary lithium battery also has a great advantage.

How to lithium iron phosphate in ternary material rise, through their own channels?

As can be seen from the above, the energy density of the lithium iron phosphate is the lowest, in the latest subsidy policy, passenger car 120 wh/kg, bus 115 wh/kg become an important watershed, only meet can get double compensation. Under the stimulus policy, promote technology upgrading as one of the keys to lithium iron phosphate is broken.

In the energy density of lithium iron phosphate batteries work of ascension, the improvement of anode materials is the key link. At present except graphite, other possible as to improve the performance of anode materials material, including, silicon oxide additives as well as a variety of, to add to the current traditional graphite, this method is more practical, and now many companies have already in use.

2, cost control, quick charge technology breakthrough, dispel the ternary bus lifted advantage

Affected by the 2016 bus to disable the three yuan, lithium iron phosphate become mainstream in the new energy bus, thanks to the rapid development of new energy bus, in all of 2016 shipments, lithium iron phosphate occupy more than seventy percent of the share. To enter in 2017, with the safety standards for unity, passenger car with three yuan thaw, but still few adopters. However, as the subsidy policy in 2018, three yuan back into the application list.

Does this mean that the back three yuan?, in fact, the answer is not clear, after the relevant standards are established, the security problems of the ternary don't have to worry about, but by inertia, the cooperation and technology, combined with the passenger car market is limited, the new energy bus and coach industry development gradually meet the ceiling. And, for commercial vehicles, also is not the primary concern of the energy density, cost, operating efficiency and so on was valued more.

In the lithium battery enterprise, two levels of differentiation is aggravating, Ningde era, BYD, Walter covered a major share of the market, and the three companies, in new energy bus, car market occupy a dominant position, from the point of market share, lithium iron phosphate is still have a lot of space.

3, arrangement in use, the problem of recycling is difficult

With the end of the lithium iron phosphate battery life, become a big problem. Compared with ternary batteries, lithium iron phosphate recycling utilization rate is low, the lack of profit, even at a loss for renewable materials recovery, this leads to the lithium iron phosphate battery recycling does not bring benefit not only, also can become a drag on.

2018 power battery recycling new rules has been clear about the recovery of body as well as responsibility, battery enterprises are also on the positive research is more green, recovery of the economy, technology, only make up a piece of short board, lithium iron phosphate in the path of sustainable development can go further.

At the same time, the pilot, and open up new markets become battery enterprise priority. After the subsidy TuiPo, cost and efficiency become the core of market attention.
