Stick to mixed technology 23 years, why is Toyota to avoid the charging lithium battery?

10.7421 million, 367,500, the former is Toyota 2019 sales data, the latter is the number of sales in TSLA2019. Although the volume is very far, this does not prevent the TSLA market value to successfully surpass Toyota has become the highest car enterprise in the world, and the ultra-high market value is an accreditation of TSLA development pure electric vehicle models throughout the automotive industry.

. The automotive industry has entered the era of new energy, and each car company is adjusting the strategic research and development of new energy vehicles..

Dynamic lithium battery as a new energy car core development technology, three-dimensional lithium-ion battery and lithium iron phosphate ion battery have become mainstream of power lithium battery. When the lithium ion battery became the main melody of the industry, Toyota played 23 years of mixed motivation technology still insisting on using NiMH batteries. The biggest competitor of sales in sales, Germany Volkswagen, has also acquired Guoxuan high-class, full layout lithium-ion battery to cater to meet Pure electric vehicle development trend.

Why does Toyota use a lithium-ion battery, Toyota has no pure electric car technology is the focus of the car market.. Toyota is developing the 100-kilometer fluoride battery Recently, the foreign media reported that Toyota is jointly developing a new generation of new energy vehicle power lithium battery technology.

It is not a mainstream lithium-ion battery, but a new fluorine. Ion battery. According to the exposed battery data, the fluorogenic battery storage energy is about 7 times that of the traditional lithium-ion battery, which allows electric vehicles to charge 1000 kilometers.

. The working principle of Toyota’s new fluoride ion battery is to transfer fluoride ions from one electrode to another electrode by fluoride ion conductivity to another electrode, and the anode or negative charge electrode is composed of fluorine, cobalt, copper, and is important. Hydrogen composition, and the fluoride battery is completely unsuitable as a raw material.

Usually used in lithium ion batteries is liquid electrolyte. This fluoride battery in Toyota is using solid electrolyte, and the maximum advantage of solid batteries is greatly reduced..

However, the fluorogenic battery is also facing a small challenge, that is, the battery can be electrically conductive when the solid electrolyte is sufficiently heated, but this may cause the battery electrode to expand. In order to solve the problem of battery expansion, Kyoto University and Toyota Research Group will produce electrodes with cobalt, nickel and copper alloy. In the moment, almost all new energy automotive companies and power lithium batteries are in “bet” three-dimensional lithium-ion batteries or lithium iron phosphate ion batteries, and these two batteries have also become mainstream of industry, with Toyota fluoride battery research Plans to be disclosed, Toyota has also been gradually moving in the lithium-ion battery field.

. Before the new energy field, the automotive electricity is coming, with the construction of the new energy vehicle, the market is predicted that Toyota will be the absolute leader in the electric vehicle..

Such predictions are not unreasonable. As early as January 1992, Toyota announced the “Toyota Earth Environment”, indicating that he will change humanity about traditional gasoline engines in new energy vehicles, Toyota in the new energy vehicle I have adhered to 23 years. Although TSLA promoted the development of pure electric vehicles, the first truly brought new energy vehicles to consumers living, but Toyota Prius, from 1997, the first generation of Prius is officially born, Toyota is mixed with sales have broken through Ten million.

Toyota has always adheres to hybrid automobile technology. This point is true, but it is not a popularity of pure electric cars. It is proud of mixing technology that has not become mainstream.

. First, under the trend of the entire automotive industry, Toyota has a disappearance. However, it is clear that the falling team is limited to the market and pure electric vehicle market insurance, and there is no detail in the pure electric vehicle technology reserves, and is diversified development.

. Second, the road of electrification Toyota’s pure tram type is really relatively slow, and the early long-term is the route of hybrid..

At present, Toyota has been focusing on developing fuel power batteries.. However, Toyota did not relax the research on lithium-ion battery.

The instability of lithium-ion batteries allowed Toyota’s attitude towards it. After all, in 2009, due to “pedal door” incident, 8.5 million cars will once again let Toyota In the face of bankruptcy, the quality of automotive quality has reached the harsh.

. In fact, the use of three-yuan lithium-ion battery models frequently prove that Toyota’s worry is not unreasonable, which may be this kind of robust market posture has created people to Toyota in the lithium-ion battery field..

R & D investment in Toyota, Toyota in the fuel power battery can be placed in front of the entire automotive industry. Taking a hydrogen fuel power cell as an example. Compared to the current mainstream power lithium battery, its environmentally friendly is greater than the former, theoretically, the most environmentally friendly battery type (emissions Closer to zero), and also have the advantages of high energy conversion efficiency and long-lasting mileage.

. However, the greatest challenge in the face of hydrogen fuel power cells is cost and infrastructure construction, and operating costs are too high, and the safety has not been introduced..

On December 15, 2014, Toyota will announce the world’s first amount of hydrogen-produced fuel power battery car Mirai in Japan. After 6 years of development, in addition to Japan, Mirai, Mirai, in other mainstream markets..

The infrastructure severely restricts the development of hydrogen fuel power batteries, and the construction of these facilities requires government power, only with Toyota personal behavior is difficult to complete. In terms of use in hydrogen fuel power batteries, practice proves that public transport and logistics models are their best carriers. Since these models are not spatially restrictions, larger volume of hydrogen fuel power cells can be carried.

. Future Hydrogen Fuel Power Battery still has its existence value will not be eliminated, and Toyota’s big handbook is not useless, and technology is also in the industry..

At the same time, the use of Toyota in the field of lithium-ion battery is also earlier than most car companies. In 2008, the battery research department was established, focusing on different kinds of batteries in lithium-ion batteries, and launching a new lithium in the same year and Panasonic Ion battery technology reserves. The third generation of Prius, the third generation of Prius is a nickel-hydrogen battery.

However, Toyota also starts lithium-ion battery test with the third generation of Prius.. The second generation RAV4EV version is the lithium ion battery pack (from TSLA).

Toyota, Toyota, which is not a blank, has been actively investing, but there is no breakthrough in key technical stages, due to the instability of lithium-ion batteries, Toyota is forced to have a large area of ​​launch market.. From nickel-hydrogen batteries to a hydrogen fuel power battery, lithium ion battery, and the latest fluorogenic solid battery, Toyota has continuously tried the possibility of diversified development of new energy vehicles on the safety basis.

. So, regardless of how the automotive industry develops, Toyota can catch up, even with its technology to bring a new change..

Dedicated nickel-hydrogen battery, such as a hydrogen-fuel power battery, lithium-ion battery, and fluoride solid state battery only technical reserve products, Toyota only loves the power lithium battery non-nickel hydride battery. Nickel-hydrogen battery Toyota has been used in 23 years, why does Toyota love nickel-hydrogen batteries? This point is nothing to do with Toyota is the Japanese company, which is well known to Japan’s natural resources, especially environmental awareness walks in the forefront, and the advantage of NiMH batteries is that recycling degradation relative to lithium-ion batteries more environmentally friendly. The important ingredients of nickel-hydrogen batteries are: rare earth, nickel, both have a high recovery value, and water use water for electrolyte solutions, it is not easy to pollute the environment, and is very friendly to the environment.

. Second, the nickel-hydrogen battery is safe, and since the electrolyte of the nickel-hydrogen battery is an aqueous solution, it is not easy to combust if there is an abnormality such as short circuit..

Although the nickel hydrogen battery is inferior to a lithium-ion battery, the mixing technology can be released by means of engine, the energy density is not the most important consideration, and the nickel-hydrogen battery life is also better than the lithium ion battery.. Due to research and development and production of nickel-hydrogen battery products for more than 20 years, quality control, quality has been well controlled.

The US “Consumer Report” experiment will open a 10-year 330,000 kilometers of Prius and a 10-year deposit only 3,200 kilometers per 3,200 kilometers, and the performance index gap between the performance indicators of the two cars is not obvious. Prove that the attenuation of nickel-hydrogen batteries is much lower than other kinds of batteries. After several years of development, pure electric vehicles have been in a bottleneck in a bottleneck based on lithium-ion batteries.

. It is undeniable that pure electric automotive technology is not fully mature, and the power lithium battery technology is still far away..

It is expected that in the future, Toyota will continue to be based on NiMH batteries for a long time before it is not mature.. At this stage, such as the three-dimensional lithium-ion battery self-combustion rate is much higher than other kinds of batteries, but benefited from high density, good energy storage effect, resistance to low temperature, and has to recognize the best choice for pure electric car market.

. Toyota blocked the development of pure electric vehicles from being unable to become the mainstream choice for the market. Announces free to open the hybrid automobile technology patent.

For this power system, countless Toyota, why suddenly open technical patents for free? The purpose is very simple, decelerating the development of pure electric vehicles, so that this power system gets more market share, keeping the advantages of mixing, unwilling to mix the market.. But everything is too late, the development of pure electric cars has stopped, and some extent this situation is also Toyota’s own mistakes.

In the early years, many cars are dreaming of thinking about this power system, but Toyota is really “too “Small gas”, it is too heavy for this system. If there is a patent, it will resort to the law. In addition to “true” Honda around Toyota patent developed its own mixed technology, many car companies choose to circumvent the mixed field, Direct development of PHEV plug-in power cars and pure electric vehicles.

Toyota’s hybrid car technology is unquestionable in the world, but the mixed motive automobile technology has lost the market advantage.. If the initial opening technology patents in the 2014 pure electric car broke out, today’s new energy car history may be rewritten, the pace of pure electric car may not be developed like this.

Mix Toyota first, but it is limited to compare itself, free open technology patents, preventing pure electric car development positive has failed. Of course, the hybrid technology is not a place argument. This view is obviously wrong.

The mixed technology car should be the best transition product in the middle of traditional cars to pure electric vehicles, just that pure electric development is expected, and the new energy vehicle life is now. Charging the problem, before the safety is completely solved, there is also enough new energy market for a long time for a long time..

Summary of the dynamic lithium battery development will not have a variety of different kinds of batteries, this is difficult to conclude in the early days of new energy vehicles, but it is sure that a little Toyota exclusible 23 years of nickel-hydrogen batteries will not become mainstream, because physical restrictions are real Too high, Toyota is hard to complete the physical breakthrough of NiM hydride batteries with a hard work.. Before the advent of the super battery, the mainstream choice of power lithium battery is still three-dimensional lithium-ion batteries and lithium iron phosphate ion batteries.

. At present, there is no clear meaning of the super power lithium battery. Once the latest fluorogenic battery breaks through the battery life, Toyota’s fluoride battery technology is possible to mean the super battery.

. Although mixing technology has missed the best popular time, the power lithium battery, the new energy vehicle field technology reserves Toyota is not a lague, not later, Toyota’s new energy technology is also diversified development, such as fuel power batteries, solid batteries, Nickel-hydrogen batteries, lithium-ion batteries, fluorine batteries, and new energy automotive technology each link or components have the first strength, one link fails to make another link to make up the mistakes, this is important for technical reserves Where is Toyota Vehicle Terrible. .
