NMC Battery VS LiFePO4 Battery 

As the power source of electric vehicles, power batteries have various cathode materials. At present, the popular cathode materials in the market are mainly lithium iron phosphate and ternary materials. The batteries of these two materials have their advantages and disadvantages:

NMC battery (NMC 811 Battery)

NMC batteries are characterized by high energy density and higher voltage, so the exact weight of the battery pack battery capacity is more significant; the car will run farther, the speed can be faster. But its weakness lies in the poor stability; if the internal short circuit or positive electrode material meets water, there will be an open fire. Generally, 18650 batteries are protected with a steel shell. Tesla's battery pack is composed of 7,000 18650 batteries. Therefore, although Tesla provides all-around protection for the battery pack, there are still fire hazards in extreme collision accidents.

According to the pyrolysis characteristics of NMC Batteries, manufacturers will make great efforts in over-charge protection (OVP), over-discharge protection (UVP), over-temperature protection (OTP) and overcurrent protection (OCP).

The electrode material of the lithium iron phosphate battery is the safest lithium-ion battery cathode material. Combined with its cycle life reaching 2000 times, the standard charging rate (5 hours) can reach 2000 times the periodic characteristics. Even if the battery plate is punctured, the short circuit will not Will explode and burn, will not catch fire when exposed to a high temperature of 350íŠ. So in terms of safety performance, lithium iron phosphate batteries are slightly better.

Due to the mature industry and the price of technology threshold and technology decline, so many manufacturers for various factors will be considered to use lithium iron phosphate batteries. We can say that the rise of new energy vehicles has an inseparable relationship with lifepo4 batteries. The rise of new energy vehicles and lifepo4 batteries has an inextricable relationship.
