Briefly describe the reason why BYD has attached importance to lithium iron phosphate batteries

To clarify this issue, let's first take a look at why BYD has made great efforts to develop lithium iron phosphate batteries. In fact, BYD had made sufficient preparations at the beginning, and then decomposed the international situation at that time. The choices made under the premise of battery technology were only the development of the times and the emergence of giants, which made BYD gradually lose its advantages. 1. The core technologies of lithium manganate and ternary lithium are in the hands of Japanese and Korean companies. In the automotive battery industry, Japanese and Korean companies have already mastered the core technologies of lithium manganate and ternary lithium. Especially for ternary lithium, whether it is technology, process or equipment, Japanese and Korean industry leaders have reached a very mature and stable stage. Therefore, when Tesla, BMW, and these international giants develop new energy vehicles, they will first choose Panasonic of Japan and Samsung of South Korea, which are relatively well-known products in the world. If BYD was involved in ternary lithium batteries at that time, it would not be able to compete with Japanese and Korean manufacturers. 2. BYD's lithium iron phosphate battery has little competitive pressure. At that time, Japanese and Korean companies basically did not set foot in lithium iron phosphate batteries, but they were not without competitors. There are two companies in the United States, A123 and Valence, which are important processors of lithium iron phosphate batteries, but at that time my country's technology was not much different from that of the United States. Therefore, if BYD chooses lithium iron phosphate battery as a breakthrough, it can quickly reach the world's excellent level. 3. my country's cobalt and nickel resources are extremely lacking. According to the 2011 National Mineral Resource Reserves Bulletin published by the Ministry of Land and Resources in 2012, my country's cobalt reserves base is 79,900 tons, the resources are 566,000 tons, and the reserves of mining significance are only 42,100. Tons, accounting for 6.5% of the 645,900 tons of identified resource reserves. my country's cobalt resource reserves account for only 1% of the global total, and its import dependence is above 90%. The ternary lithium battery formula is inseparable from the two precious metals cobalt and nickel. Moreover, these two precious metals have international futures trading, and their prices are not only high, but also volatile. The lithium iron phosphate battery does not have the above two precious metals, so this is why BYD originally developed the lithium iron phosphate battery. 4. The stability of lithium iron phosphate battery at high temperature. When the car battery technology is not very mature, the battery will often explode (even at present, Tesla still has not been able to completely deal with the safety issue). Therefore, safety is regarded as It is the number one car battery. The lithium iron phosphate battery is relatively stable under high temperature conditions. Therefore, from the perspective of safety, the lithium iron phosphate battery has naturally become the best choice.
