Many people are talking about LiFePO4 vs NMC batteries. A LiFePO4 battery is characterized by stable thermal stability, low production cost, long service life, and so on. Despite this, its anti-low temperature performance is lacking. In cold temperatures below minus 10 degrees Celsius, although the battery can be used normally, charging efficiency is significantly reduced.
What’s LiFePO4 or LFP battery?
LFP (Lithium Iron Phosphate) batteries are a type of lithium-ion battery known for safety, long cycle life, and thermal stability. Their cathode material, iron phosphate, enhances safety, reducing the risk of overheating and thermal runaway. LFP batteries have a longer cycle life, enduring more charge and discharge cycles without significant capacity loss.
While they offer these advantages, their energy density is generally lower than some other lithium-ion batteries. Popular in electric vehicles, renewable energy storage, and portable devices, LFP batteries excel in applications prioritizing safety and durability, making them a preferred choice in various industries.
What’s NMC battery?
NMC (Nickel Manganese Cobalt) batteries are a type of lithium-ion battery renowned for a balance between energy density and performance. With a cathode composed of nickel, manganese, and cobalt, NMC batteries offer a compelling combination of high energy capacity and improved stability. This chemistry provides versatility, making NMC batteries suitable for various applications, including electric vehicles and renewable energy storage systems.
NMC batteries exhibit a good compromise between safety, energy density, and cost, making them prevalent in the evolving landscape of battery technology. Their widespread use contributes to advancements in sustainable energy solutions and portable electronic devices.
LiFePO4 vs Ternary (NMC) Batteries Comparison
A Comparative Analysis of Lithium Iron Phosphate and Ternary Lithium Batteries. This examination explores essential factors such as energy density, thermal safety, charging efficiency, and cycle life, revealing the strengths and trade-offs of these prominent lithium battery technologies.
Energy density comparison
An index of battery energy density affects the endurance performance of new energy vehicles. A lifepo4 battery cell has an energy density of only 150Wh/kg, whereas a ternary lithium battery cell has an energy density of more than 220Wh/kg. An ternary lithium battery, for example, has an energy density 1.5 times higher than a lithium iron phosphate battery for the same weight, enabling new energy vehicles to last longer.
Thermal safety comparison
In comparison with the ternary lithium battery, which has an absolute advantage in safety, lithium iron phosphate battery has the best thermal stability currently. It is safe to assume that lithium iron phosphate batteries reach a maximum electric temperature of 350°C, and chemical composition inside the battery must reach 500-600°C before they decompose. It will begin to decompose at about 300°C due to its thermal stability.
Efficiencies of charging
There is more efficiency in ternary lithium batteries. Experimental data indicate no significant difference between the two when charging below 10°C, but they will separate once charging is above 10°C. There is a five-fold difference between the constant current ratios of ternary lithium batteries and lithium iron phosphate batteries when charging at 20°C.
Cycle life comparison
Battery cycles last longer with lithium iron phosphate than with lithium ternary. At 1000 cycles, the capacity of the lithium ternary battery drops to 60%, but its academic life is 2000 cycles. In spite of Tesla’s relatively good ternary lithium battery, it is only capable of conserving 70% of its power after 3000 cycles. A lithium iron phosphate battery can maintain 80% capacity after repeated cycles.
Unlike lithium batteries, lithium iron phosphate batteries are safe, durable, and heat-resistant. Lithium ternary batteries are lightweight, fast charging, and temperature-resistant. In order to coexist, they must be able to adapt in time and place in order to coexist.
