What are the advantages of ternary lithium batteries compared to lithium iron phosphate batteries?

What are the advantages of ternary lithium batteries compared to lithium iron phosphate batteries? First of all, the battery attenuation of the lithium iron phosphate battery is relatively serious, and the ternary lithium battery can still guarantee good discharge performance at low temperatures. Therefore, in the past, BYD cars sold less in northern my country, and used ternary lithium. After the battery, this situation can be greatly changed. The energy density of the ternary lithium battery is relatively high, and the charge and discharge efficiency is high. Since the cruising range is an important indicator of pure electric vehicles, compared with ternary lithium batteries, lithium iron phosphate batteries have better advantages in battery energy density, and the cruising range of pure electric vehicles can be guaranteed. At present, most of the world's pure electric vehicle companies are using ternary lithium batteries, especially after Tesla went public, even leading the development of ternary lithium batteries. If only BYD uses its own lithium iron phosphate battery, it will be difficult to promote it. Therefore, BYD and Guoxuan Hi-Tech have established a joint venture company to jointly develop and process ternary lithium batteries. Charging is also an important part of the actual use of electric vehicles, and the ternary lithium battery has a very big advantage over the lithium iron phosphate battery in terms of charging efficiency. When the ternary lithium battery and the lithium iron phosphate battery are charged below 10C, there is no significant difference in the constant current ratio. When the rate is above 10C, the constant current ratio of the lithium iron phosphate battery decreases rapidly, and the charging efficiency decreases rapidly. Regarding family cars, the rated cycle life of ternary material lithium batteries and lithium iron phosphate power lithium-ion batteries far exceeds the actual user's usage habits, so the service life can be completely assured. Assuming an average charge for 3 days a year, it takes about 6 times to charge in 1 year, and it takes about 8 years to complete the cycle life of 1,000 times. This basically exceeds the current average replacement cycle of Chinese consumers. The characteristics of ternary lithium battery: small size, can be installed with larger capacity, little performance degradation in winter, larger initial capacity, obvious mileage advantage than iron-lithium battery, general life span is about 5 years. According to the data released by the my country Automotive Power Lithium-ion Battery Industry Innovation Alliance, from January to August 2019, my country’s power lithium-ion battery installed capacity has accumulated 38.2GWh, of which the ternary lithium battery installed capacity has accumulated 26.1GWh, accounting for the total installed capacity. The vehicle volume is 68.4%; the total installed volume of lithium iron phosphate batteries is 11.0GWh, accounting for 28.8% of the total vehicle volume. According to the data, the ternary lithium battery has overwhelming advantages. In comparison, ternary polymer lithium batteries are superior to lithium iron phosphate batteries in terms of energy density ratio, and lithium iron phosphate batteries are better than ternary polymer lithium batteries in terms of environmental temperature adaptation and stability.
