Lithium manganese acid battery plays an important role in electric vehicle in the future

Talking about power batteries, when the red is undoubtedly a ternary battery. lithium iron phosphate is slightly less coquettish. As for lithium manganate batteries, it seems to be an ancient creature, and then talk about it a bit out.

However, Xingheng Power, one of the oldest power battery companies in China and established in 2003, is still adhering to the core of lithium manganate, and the manganese multivariate lithium power battery technology route. Besides, they did a good job --

In 2017, the total shipment volume of Xingheng Power New Energy Vehicle Power Battery was about 700 million watt-hours. Revenue was 1.436 billion yuan and net profit was 202 million yuan.

"Manganese-based batteries are one of the most suitable choices in the future of electric vehicles." Feng Xiao, chairman of Xingheng Power, said, "We are determined to be the leader in the segmentation of commercial vehicles, especially logistics vehicles. ”

He also added that the so-called faucet must be the "real electric logistics car running on the street" supporting the most.

Listen to him insist on the logic of manganese power cells, observe the market demand for manganese power cells, perhaps, we must re-understand manganese power cells.

Power Battery Japan and South Korea is "Manganese"

What is the most widely sold electric car in the world so far?

It is the Nissan Leaf. Since its launch in 2010, it has accumulated sales of more than 320,000 units.

What kind of battery does the leaf use?

Lithium manganate battery.

Not only is Nissan's supplier of AESC, GM Volt and Renault ZOE's supplier LG Chemical, but also uses lithium manganese batteries. In addition, there are Toshiba, Hitachi, and LEJ using the lithium manganese acid technology route. In Japan and South Korea's power battery technology route, although ternary is an important one, lithium manganate is also the same.

However, lithium-manganese batteries have not been mainstream in China, with shipments in the new energy car market in 2017 accounting for only 4.25 % of the total market share. Mainly used in passenger cars, logistics vehicles, in the passenger car field is also slightly supporting.

However, Xingheng Power is unique among ternary batteries and lithium iron phosphate batteries. With its manganese-based multi-component lithium-ion battery products, it has nearly 17,000 new energy vehicles in 2017, with a total power of about 700 million watt-hours. Major customers include Chongqing Ruichi, Dongfeng Motor, Chongqing Changan and other special car companies, including Dongfeng, Changan, Chery and other passenger car companies. The market share of special vehicles is ranked in the top five.

Logic of selecting lithium manganate batteries

At the beginning of May, when the "Electric Car Observer" went to Xing Heng in Suzhou, he could not wait to find out why Xing Heng chose lithium manganate.

"I must ask which technical route is good for ternary, lithium manganate, and lithium iron? " said Feng xiao. "These kinds of materials have their own advantages and disadvantages. "

"If you are talking about safety, the best is iron lithium, followed by manganese lithium, and the worst is ternary;

If you talk about energy, the best ternary, followed by lithium manganese, the worst is lithium iron;

If you ask about the cycle life, the best is iron lithium, followed by ternary, the worst is manganese lithium;

In terms of cost, the best is lithium manganese, the middle is lithium iron, and the worst is ternary;

If you ask about the width of the temperature, the best is lithium manganese, followed by ternary, and the worst is lithium iron. "

Fengxiao believes that "lithium manganese acid batteries are one of the most suitable options for future electric vehicles. He listed several core reasons.

The first is the most important safety for power cells. "It's moderately safe. Within 100 degrees, I think lithium manganese can solve the safety problem. And if the ternary is greater than 40 or 50 degrees, I don't think it will solve the security problem. "

Secondly, lithium manganate batteries can meet the basic applications of the market. "I can reach the energy density and I can reach the cycle life. "

Relative to ternary batteries, lithium manganate energy density is relatively low, how to solve? "Pure manganese lithium does not reach the specific energy required by the country today. I will add three yuan to it. Try it bit by bit, I might be able to add to 50 % of the three later. The other part of the person who makes pure ternary, under the cost challenge, will inevitably be adulterated with lithium manganese acid, from 10 % of lithium manganese acid to 20 %, or even 50 %. Who is lithium manganate and who is ternary? Under the premise of meeting the basic needs of the market, who has the ability to drink more lithium manganese acid, who makes more money. "

For lithium manganate to challenge the biggest cycle life, Xingheng Power's products can ensure that 2000 cycles have a capacity of more than 80 %, ensuring that commercial vehicles run 200,000 kilometers in 5 years or 8120,000 kilometers in passenger vehicles. "If you want to run an average of 300 kilometers per vehicle, you want to run more than 400,000 kilometers, you need to have 1,500 cycles. "

"The next most important thing is cost. The cost is optimal for lithium manganese. "Fengxiao recalled that in 2015, without a rapid increase in the price of power battery materials, lithium manganate was about 30,000 tons, lithium iron was 80,000 to 90,000, and three yuan was 110,000. "What did it become after three years? Lithium manganate is now 60,000 tons. Iron lithium is more than 80,000, no change, after experiencing a price correction, because of the demand for passenger cars down. Three dollars has now become 250,000, 270,000. "

"Of course, the choice of lithium manganate, as well as our comparative advantages from design to management, to engineering, is based on a deep understanding and foundation of the product through 15 years of precipitation and accumulation. It gives us a cost advantage over the average manufacturer, and that's what we do. "

As a result of this series of cost advantages, Xing Heng has prepared for the product of 1 yuan / Wh at the end of 2018.

The logic of markets and strategic positioning

Xingheng Power's 2017 revenue reached 1.436 billion yuan and net profit was 202 million yuan. Moreover, Xing Heng Power does not have a huge accounts receivable problem.

Do the same power battery, the star constant power supply is not the same, sum up, it is selected industry, selected customers, selected models.

"The first sentence of my core strategy is called two-wheel drive. The left hand has light vehicles, including electric bicycles, electric motorcycles, electric tricycles, and low-speed four-wheelers; I have an electric car on my right hand. Without the market of two industries, in the course of policy fluctuations, the market change process, can not bear the risk. Today, even if an electric car battery can't sell, I can't die. I can still have a good return and profit. "

Xingheng Power has been operating in the light electric vehicle field for 15 years and is the first lithium electric company in the domestic electric two-wheeler market. In 2017, Xing Heng Power shipped 1.2 million batteries in the light vehicle industry. In addition to existing European markets and domestic customers, overseas also opened up Southeast Asian markets.

In the selection of models, the choice of Xing Heng Power is mainly commercial vehicles, taking into account passenger vehicles, but focusing on the opportunity of passenger vehicles to operate vehicles. "In the next three to four years, Xing Heng will resolutely make a leader in the field of commercial vehicles, especially logistics vehicles. Feng xiao said, "Don't look at the main dish as a passenger car, but the electric logistics car is the first model that can form a virtuous cycle, that is, consumers are willing to use it, use it for a good deal, and take the initiative to buy it, not because of the license. reason. "

As for passenger cars, "I am willing to stare at the network and taxis, and with one or two mainstream passenger car depots, it is OK to really do one or two models. "

The Fundamental Logic of Developing Electric Vehicles

There is obviously a more fundamental logic behind the logic of Xing heng Power's choice of lithium manganate as the core, manganese multivariate lithium technology route, and its own strategy. This is the fundamental value of Xing heng Power to the development of electric vehicles.

"Electric cars are competing with internal combustion engines that have been developed for more than a hundred years. Feng Xiao said, "It is nothing more than efficiency, cost-effectiveness, and efficiency -- allowing people on this planet to travel in the least costly way. This is the core issue. "

Specifically to the development of electric vehicles in China, "we must calculate the economic account, we must calculate the account. "How does Xing Heng calculate?

"The cost of electric vehicles is on the battery. With today's technical content and knowledge level, 1 yuan per watt hour is already very great. Whether it is a car or a truck, a group of batteries must have a temperature of 40 or 50 degrees. The battery has to have four or five thousand dollars."

A key assumption to get the $40,000 back is the difference between a hundred kilometers of fuel consumption and electricity consumption. "(100 kilometers of electricity is more economical than oil) 50 yuan is objective. If you have a private car, the entire life cycle can only run 100,000 to 120,000 kilometers. You can only save money on a set of batteries and it will take 5 to 7 years. This is not cost-effective. "

"If it's a logistics car or a truck, it can run 200,000 to 300,000 in the product life cycle.(The oil difference accumulates), in addition to covering the cost of the battery, it can also save two more batteries. money. The business is not bad .... it's a good bet. "

"If it is an online car or taxi that can run 400,000 to 500,000 kilometers throughout the life of the product, in addition to covering this group of batteries, it can save four or five additional batteries. It is a very perfect financial model. Good business. "Fengxiao added," Of course, the premise is that the quality must pass, and you can not use the three groups to carry the 40,000 or 500,000 kilometers. "

Such economic accounts are not counted as government subsidies. Based on this, Fengxiao said, "We can indeed see that electric cars can match the efficiency of the internal combustion engine industry, so I am more positive and optimistic. "In the economic account of the" internal combustion engine ", the cost advantage of lithium manganate can be realized faster than the paper advantage.

In fact, Fengxiao himself was the first to work for Lenovo Investment. In 2003, he invested in Xing Heng Power to invest himself in it. Later, he gradually promoted himself. He served as sales manager, product manager, PACK director, general manager of the business department, deputy general manager of the company, and general manager. Until the chairman.

In addition, Huangxuejie, a researcher at the Institute of Physics of the Chinese Academy of Sciences, is the chief scientist; Wangzhengwei, vice president of battery development and technology management with more than 28 years of experience; There is a national "863" plan "Ninth Five-Year Plan" major project member of the Nickel Hydrogen Battery Expert Group Yuguohua as a consultant.

On the basis of existing accumulation, Xingheng Power also has the continuous accumulation of talents and capital. As a former investment manager, Feng Xiao said, "Today, Xing Heng is still ranked fifth in the power lithium battery industry, but it has the value and ability to grow rapidly. "(finished)
