Ferrous lithium phosphate vs ternary lithium portable power supply: complete comparison of adaptation scenarios
Let's talk about the core difference background color:
Differences in core characteristics (determining applicable scenarios)
form
Comparative dimension Ferrous lithium phosphate portable power supply (LFPO4) ternary lithium portable power supply (NCM ternary)
High safety factor, high temperature resistance, no fire and no explosion, low spontaneous combustion due to puncture/overcharge, high temperature, easy thermal runaway and fire, and high risk of collision and extrusion.
The cycle life is 3000 ~ 6000 times of charge and discharge, the life is very long 800 ~ 1500 times, and the life is much shorter.
The low temperature performance is below zero, the environmental capacity is greatly attenuated (only about 60% of the capacity is left at -10℃), the cold resistance is excellent, and the discharge loss in winter in the north is small.
The energy density is low, the fuselage with the same capacity is heavier and higher, and the volume with the same power is smaller and lighter.
The peak power of discharge is continuous, the output of high power is stable, and the instantaneous explosive power is stronger.
The price is more cost-effective and the same capacity is more expensive.
First, Ferrous lithium phosphate portable power supply is suitable for the scene.
Main products: safe and durable, long-term standby at home, outdoor permanent, high temperature environment, long-term storage of goods, high-power continuous power consumption.
Household emergency power supply (preferred)
Power outage standby, refrigerator life, lighting, water pump, emergency of small household appliances in the whole house; If it is placed in the storage room at home all the year round, the standby loss will be low if it is not used for several months, and it will not be spontaneous combustion because it is put aside. It is the safest for the elderly and children to stay at home, and the life decay will be slow after 5-8 years of long-term use.
RV/bed car long-term residence, go on road trip permanent camping.
Long-term parking life: cooking, boiling water, car refrigerator, induction cooker, rice cooker continue to use high power; During the day, solar panels are repeatedly charged and discharged, and the cycle life advantage of iron and lithium is full, which is extremely stable in the wind, sun and high temperature environment.
Site construction, field survey, agricultural outdoor work
The construction site is exposed to the sun in the open air and used in high temperature environment in summer; Drive electric drill, angle grinder, water pump and other continuous high-power equipment, not afraid of high temperature and harsh environment, durable and anti-manufacturing.
Stall night market, snack mobile vendors
Continuous power supply throughout the day: freezer, cooking pot, lighting lamp and fan work for a long time and charge and discharge repeatedly every day, with long service life and lower use cost.
Long-term storage, disaster prevention and emergency stockpiling
The standby power supply for earthquake and flood disasters can be stored for several years and replenished regularly, which is not easy to age and has the highest safety priority.
Outdoor use all year round in hot areas in South China.
In summer, the continuous high temperature makes lithium ternary easy to burn and decay, and the tolerance of iron and lithium is better.
Ferrous lithium phosphate is not suitable for:
Go out for a short trip in the cold winter in the north, and pursue the extremely small and light short-distance travel with you.
Second, ternary lithium portable power supply is suitable for the scene
Main products: light and compact, low temperature and cold resistance, short-distance travel with you, instant fast charging and lightweight requirements.
Short-distance self-driving in winter/camping in snow in winter in the north
Outdoor at minus ten degrees in winter, the capacity attenuation of ternary lithium is much less than that of Ferrous lithium phosphate, and it can release more electricity in winter, so it is the first choice for traveling in autumn and winter in the north.
Short-distance hiking, mountaineering, and cycling are lightweight and portable.
You need to walk with your back and hand: ride the power supply and carry it with you on foot. The weight of the fuselage is 20%~35% lighter with the same amount of electricity, and it is portable to crush iron and lithium.
Digital enthusiasts travel short distances: laptops, cameras and drones are charged.
Mainly based on low-power digital equipment, the pursuit of compact and high-value body, daily commuting, business trips with computers, cameras, Yuntai charging.
Short-distance luxury camping (1~2 days exquisite camping)
There is no need for continuous high-power cooking. The main power supply is lighting, coffee machine, projector and mobile phone digital. It values beauty and portability, and it is stored home after use. The frequency of charging and discharging is low, and the short life span cannot be reflected.
Equipment require instantaneous ultra-high peak power
Occasionally start high-power impact appliances (small air compressor, high-power car vacuum cleaner), and ternary lithium instantaneous discharge is more explosive.
Lithium ternary is not suitable for:
Long-term standby at home, high-temperature exposure environment, daily high-frequency repeated charging and discharging, and family disaster prevention reserves with old people and children (higher security risks).
Minimalist shopping formula
Home power outage standby, RV permanent residence, site stall, high temperature in the south, want to use for more than five or six years → Ferrous lithium phosphate.
Winter use in the north, hiking and cycling with you, short-distance exquisite camping, pursuit of lightness and compactness → ternary lithium.
