Tesla why not use lithium iron phosphate as the anode material of lithium ion battery?

Source: 2020 - 03 - 29 15:06 hits: time why not use the lithium iron phosphate as the anode material of lithium ion battery? , a concept first correct 'lithium is what we usually call' lithium ion batteries' short, and you say 'ferroelectricity, lithium iron phosphate is used as the anode data of the lithium ion battery, it is' lithium. Well, to answer now, shallow phenotypic simple version of the summary: tesla adopts 18650 lithium-ion batteries, panasonic to NCA was right in the end, the planning of complex battery processing system, as far as possible to ensure and improve the efficiency and safety of battery operation. As to whether the absolute safety, this can't answer, if you want to say that spontaneous combustion, I also want to say gasoline vehicles also spontaneous combustion in the summer. All-electric car what is the biggest problem, They can use gasoline, not to mention, plug-in hybrids and all-electric hybrid) 吗? Range anxiety, is not far away, because the battery can store the energy density is too low, now car batteries are commonly energy density of 100 ~ 150 wh/kg, the value of the gasoline is about 10000, so even if you like the tortoise carrying a pile of battery, you can't solve this problem. Every day we make fun of the electric car charging ran half of power to do, low energy density is harmless. At present the biggest drawback is the low energy density batteries, lags far behind Moore's law. Don't talk about lithium, even if they do not have a high energy density, the key is that they are far from practical also so as to why we do not use batteries, lithium iron phosphate is the first reason I want to say, is capacity, lower energy ( Energy is the capacity of the Ah get Wh) multiplied by the voltage The actual car battery pack is the combination of series and parallel, increase the voltage to the requirement of series, at this point, the single tank voltage and consistency between different battery capacity is very important, said light capacity is not rigorous. Institute of my homework at home to do some promote the lithium iron phosphate product research and development, but also watch some other materials, lithium batteries and electric cars, so crap here ~ ~ ~ ~ now the beginning of the semi - rich Academic smidar open ~ ~ ~
