The ternary lithium and lithium iron phosphate battery compared with six different

The ternary lithium and lithium iron phosphate battery compared with 6 different 1. Coach to choose byd, cars tesla. It said the differences in both the volume. From the point of current technology, three yuan energy density of lithium-ion batteries in 200 wh/kg, the future could reach 300 wh/kg; The lithium iron phosphate batteries at present basically hovers around 100 ~ 110 wh/kg, the individual can reach 130 ~ 150 wh/kg, but very difficult to break through 200 wh/kg. Therefore, the ternary material than the lithium iron phosphate power battery can provide a times more space, it's important for limited space car. Tesla ternary lithium batteries, byd lithium iron phosphate batteries, so there are 'coach choose byd cars and choose tesla said. 2. Because the same energy density is big, the weight is much smaller, light weight and small footprint determine the ternary lithium battery new energy cars less power consumption, thus faster and stronger battery life. So, car use ternary lithium batteries can run further, and new energy vehicles currently lithium iron phosphate was largely used in city bus, because a life, need not long distance charging pile can charge. 3. Passenger bus, of course, take the lithium iron phosphate batteries more core is based on safety considerations. Tesla cars more than with the fire accident, the reason is that tesla's battery by about $7000, 18650 yuan of lithium battery, the units of the battery or the battery pack if there are any internal short circuit will produce flame, extreme collision accident, short circuit caused by fire. And lithium iron phosphate material in short circuit is not burning, high temperature resistant performance is larger than that of ternary lithium battery is superior. 4. The lithium iron phosphate batteries, while high temperature resistant, low temperature resistance of the ternary lithium battery is better, is a major technical route, the manufacture of lithium-ion batteries at low temperature at minus 20 & deg; C, the ternary lithium battery can release 70. 14% of capacity, and lithium iron phosphate batteries can only release 54. 94% of capacity, and due to the low temperature condition, the ternary lithium battery discharge platform is much higher than the lithium iron phosphate battery voltage platform startup faster. 5. Charging efficiency, higher ternary lithium batteries. Lithium battery is to use current limiting pressure limiting method, namely in the first stage to do constant current charging, the current is big, high efficiency. Constant current charging after reaching a certain voltage, constant voltage charging into the second stage, at this point, the current is small, efficiency is low. Therefore, the charging efficiency is measured by constant current charging power and the ratio of the total capacity, battery is called a constant current ratio. Experimental data show that, under 10 c charging condition difference is not big, but more than 10 c will distance, charging 20 c, ternary lithium batteries of constant flow ratio is 52. 75%, lithium iron phosphate batteries constant current ratio is 10. Five times as many as 08%, the former is the latter. 6. Cycle life, superior to lithium iron phosphate batteries ternary lithium batteries, the theory of ternary lithium battery life is 2000 times, but basically to a 1000 - cycle, the capacity decay to 60%; Even if the industry's most outstanding brand tesla, after 3000 times also can keep 70% of the battery, and lithium iron phosphate batteries through the same cycle, and 80% of capacity. Above is the ternary lithium and lithium iron phosphate batteries
