Can the titanate charging lithium battery play a beautiful 'turn over?

For the power lithium battery industry, capital seems to be especially favored in recent years. Not long ago, the subsidiaries of Zhongda Electric Co., Ltd.

jointly in Yinchuan Jin Zhihui proposed a joint venture of 350 million yuan, and a micro-macro power system (Huzhou) Co., Ltd., which was sold in lithium titanate and fast charge technology.

. From the chairman of Gree Electric, Dong Mingzhu entered the primary silver new energy, to the microaving power, the lithium-ion battery, the lithium-based ion battery, the lithium ion battery category under the huge shadow of lithium iron phosphate, in the electric vehicle Describe the mileage, charging efficiency problem, industrialized progress slowly, seems to have finally ushered in turning over. Long short board has a distinctive “old fresh meat” out of his lively, inner way to see the doorway.

Dong Mingzhu was stirred in public opinion, but the company’s observation point in the industry was in terms of titanate.. About acquisition of Yintong, Dong Mingzhu said that the reason is willing to use all the family to invest in Yinlong because it is optimistic about the lithium titanate technology of Yinlong.

. As a new foreman, Dong Mingzhu is a reason for the lithium titanate. There are such a long time: long service life, can adapt to high-precipitation temperatures, good security, and in the energy storage market, etc.

. But in fact, the lithium titanate ion battery is not a fresh technology..

As an important material, the advantages and disadvantages are more obvious.. Previously, there were three major “short boards”, and the large-scale commercial application of lithium titanate has been limited.

. According to experts, one of the short board is high temperature flatulence. When the lithium titanate is used as an aperture material, the electrolyte is easily used interpretation and the gas precipitation occurs during the charge and discharge cycle reaction, so the ordinary titanate lithium-ion battery is prone to the flatulence, resulting in a battery-core drum, and electrical properties.

A large decline, greatly reduced the theoretical cycle life of lithium titanate ion batteries, which can be described as a most important reason for the large-scale application of lithium titanate ion batteries.. Second, the energy density is low, that is, the amount of electricity stores is not much.

. Compared with the carbon negative material battery, the same volume and weight can only save half of the electricity, and the battery is only half..

Therefore, the volume and weight of the lithium titanate ion battery are large, which means that the passenger car will be reduced.. Commercialization only “fast” does not break, as the other side of the coin, the lithium titanate also has its own uniqueness, especially in commercial vehicles, especially the passenger car: The first is a wide range of work temperatures; Lithium titanate operating temperature covers -30 ¡ã C to 60 ¡ã C (no heating device), can completely deal with the cold weather in the northern region; second is long life, high safety performance.

Compared with the conventional negative electrode material graphite and silicon, lithium titanate can greatly reduce the loss of lithium ions and electrolytes during storage and use, prevent attenuation of battery capacity.. Of course, if she still relying on these people have long been known, the lithium titanate is clearly unable to toss these wind waves.

. In the insiders, on the basis of continuous improvement of energy density, it is possible to achieve fast charge. It is a technical factor that is sought after by lithium titanate.

The back is the reality of electric vehicles’ commercialization of bottlenecks.. At present, domestic mainstream passenger car power lithium batteries generally uses three-dimensional lithium and lithium iron phosphate ion batteries.

. The former is “temporarily called” due to safety issues..

Although the lithium phosphate ion battery is still dominated, the graphite material is a negative illusion, such as easy to form a SEI film, resulting in lower charge and discharge efficiency, no reversible capacity, etc.. The most direct impact is that most electric cars “do not dare” to make quick recharge, but only the form of slow charging.

This means building a large number of supporting facilities, the investment and construction cost is extremely high, eventually seriously restricting the efficiency of vehicle operation, winning the spontaneous demand for consumers to electric vehicles, and achieves disabilities of commercialization. It can be seen that before the battery technology has led a major breakthrough, only “fast” does not break, and become the universal requirement of “speeding” in electric vehicles..

Wang Bing, director of the Ministry of Science and Technology Electric Automotive Major Project Supervision, said that fast charge-type battery technology has been widely accepted on my country’s pure electric bus, the total amount of more than 4,000 units, good operation, and economic analysis show that the fast recharge has a good Sustainability, it is expected to be a feasible method for electric transport electricization. It is not the same as a media called the media. Who masters the core technique of lithium titanate materials, who will have the capital of the world, the blue sea boat.

Although this paper is quite exaggerated, the titanate is really fast to make up for its own short board.. Under the continuous technological innovation of each company, its performance is optimized.

According to media reports, Zhuhai Yinlong is developing the 5th-generation titanate lithium-ion battery, and the energy density will increase to the level similar to the current phosphate ion battery energy density.. Many battery companies including micro-macro power have improved the energy density of lithium titanate ion batteries.

. Song Han, vice president of micro-macro’s power market, said that in 2013, microaving has introduced a second-generation fast charge battery LPCO lithium-ion battery with 120WH / kg, which has currently shipped in micro-macro-powered lithium battery. 80% of the quantity; 2017 is about to launch fast charge battery products, while maintaining fast charge and long life, energy density can reach 170Wh / kg.

Micro-macro motivation has been layout on future product planning, and planning 230WH / kg and 300Wh / kg fast charge battery products. However, the dispute between the battery technology, many industry insiders have said that the advancement of technology will never end, can’t be lost in a moment..

Whether the lithium titanate ion battery is also different characteristics, it is suitable for different fields, and is in the direction of future update.
