Analysis of ternary lithium batteries or lithium iron phosphate batteries for electric vehicles

Analysis of Tri-Lithium/Lithium Iron Phosphate Batteries for Electric Vehicles No matter what brand of lithium batteries, an open flame will occur when the internal short circuit or the anode material meets water. Even if the 18650 battery is protected by a steel case, it still cannot withstand extreme shocks. But as long as it is not more likely to burn in extreme accidents than an internal combustion engine fuel tank, I think Tesla’s battery management system has hardly solved the battery safety problem. With its intelligent battery management system, Tesla has been able to increase the total score of the three-component lithium battery from 270 points to 350 points. The biggest disadvantage of lithium iron phosphate is its low energy density (110WH/Kg) and large capacity attenuation at low temperatures (approximately 55% of the capacity at 25℃-10℃). The advantages are also quite obvious, especially for my country's auto companies. my country has abundant lithium reserves. The world has proven reserves of 13 million tons. By 2011, my country has proven reserves of 3.5 million tons. The iron oxide phosphate reserves of cathode materials are abundant, and the price of cathode materials after mass production is still very high. Congo has half of the world's reserves, Australia 21%, and my country 1%. Using lithium cobalt oxide or cobalt ternary material batteries, the cost of processing electric vehicles in my country is very passive. Lithium iron phosphate batteries are easy to discharge at 20C, so hybrid vehicles with small batteries should first consider lithium iron phosphate batteries. After 3000 cycles from 0% to 100%, the capacity can only decay to 80%, and the long-term decay rate of complete storage has not been exaggerated. Puncture, short circuit, and 350℃ high temperature combustion will not explode. These advantages make my country's automobile manufacturers, especially those who develop and process lithium iron phosphate, unlikely to choose other types of batteries. Ternary lithium battery + excellent battery management system will win. Sometimes products do not always sell well. The author is more optimistic about the battery technology led by Tesla: battery management is the core. Through Musk’s interview, I know that Tesla’s purpose in building excellent electric vehicles is to reduce carbon emissions and use clean energy to make profits. Open patents will lower the threshold of this plan, and more manufacturers will follow suit. The more manufacturers involved, the happier Tesla is, which is consistent with their intentions. I often listen to domestic electric cars talking about overtaking in corners. Automobile is a comprehensive industry, including machinery, electronics, automation, materials, basic sciences, management, finance, law, education, medical care, etc. Together, they constitute the level of the entire automotive industry, and can even be said to be the epitome of a country's comprehensive strength. The current situation in my country is far behind the developed countries, and the automobile industry is far behind the developed countries. It has certain advantages. A few companies with operational advantages can only shorten the gap with other companies and are far from overtaking. Of course, I look forward to surpassing in my lifetime. This requires the efforts of us and the next generation. As long as Tesla does not get involved in the research and development of lithium iron phosphate electric vehicles, I believe that in the long run, the use of an excellent battery management system + ternary lithium battery materials will go further than the application of lithium iron phosphate. In 20 years, electricity will definitely replace fuel oil. Compared with cars using internal combustion engines, no matter what kind of battery is inconvenient, there are still some immature batteries. For example, Tesla is developing an aluminum-air battery car. Half of the world’s 2 trillion barrels of easily exploitable crude oil has been used up since 1970. The remaining 1 trillion barrels will be used up in 25 years. In contrast, the price of Brent crude oil fluctuated around $10 in 1998, while this year's price fluctuated around $100. In the future, when you drive a fuel-powered car, the fuel cost per kilometer is 5 yuan. Whether it is a lithium battery car or a fuel-powered battery car, you will develop a functional method suitable for your own characteristics.
