At present, new energy vehicles and other related power supply equipment mainly cooperate with lithium iron phosphate battery and lithium iron phosphate battery, among which lithium iron phosphate battery accounts for the largest proportion, reaching 67.37%, followed by lithium iron phosphate battery. Here is a brief comparison between the two.
Cost
First of all, the cost of lithium iron phosphate battery does not contain cobalt and other precious metals, so the cost of raw materials is low, and the price will be a little cheaper, while that of lithium ternary battery is on the contrary, not only the cost of raw materials is high, the threshold of production technology is also high, but also the price will be a little more expensive.
Energy density
The energy density of lithium ternary battery is higher than that of lithium iron phosphate battery. The energy density of lithium ternary battery is about 170-200Wh/kg, while that of lithium iron phosphate battery is 130-150 Wh/kg. It can be seen that under the same volume and mass, it means that under the same energy, the volume and weight of the ternary lithium battery will be smaller.
Stability
The performance of lithium ternary battery is not as good as that of lithium iron phosphate battery at high temperature (over 200 ℃), but it performs better at low temperature, can maintain stable discharge performance and has higher performance.
From the above points of view, both of them have advantages and disadvantages in terms of battery. They are the most mainstream choice of power battery in the market at present. Therefore, we should not be misled by some We-media to think that lithium iron phosphate battery must be more expensive than lithium ternary battery than lithium ternary battery, which is inaccurate. At the same time, for the current energy storage battery, lithium iron phosphate battery is better, because lithium iron phosphate battery has reached the top of the technology, The ternary lithium battery is still in development, and it is possible to surpass lithium iron phosphate in the future.
So no matter which type of battery outdoor power supply is selected, there will be no big gap in terms of safety, and the gap is more reflected in the quality control and the conduction of battery protection application.
