LITHIUM IRON PHOSPHATE
What is Lithium Iron Phosphate?
Lithium iron phosphate battery, a lithium-ion battery using lithium iron phosphate (LiFePO₄) as the positive electrode material and carbon as the negative electrode material. The rated voltage of a single cell is 3.2V and the charge cut-off voltage is 3.6V~3.65V. Advantages LiFePO₄ battery: high working voltage, long cycle life, good safety performance, good high-temperature resistance, low self-discharge rate, and no memory effect.
Why FOSSiBOT Chooses LiFePO₄
LiFePO₄ battery positive electrode material electrochemical properties are relatively stable, which determines that it has a smooth charging and discharging platform. So the battery structure will not change during charging and discharging process, will not burn and explode. And even in special conditions such as short circuit, overcharge, extrusion, pinprick, it is still very safe.
Battery Life Cycles To 80% Of Health
The cycle life of LiFePO₄ batteries can reach 3,000-5,000cycles or more for portable power stations, guaranteeing a service life of over 10 years, which is higher than the cycle life of ternary batteries of more than 1,000 times, while the cycle life of long-life lead-acid batteries is 300 times or so. Also LiFePO₄ battery can reach 100% depth of discharge (DOD). Why does that matter? Because it means that with LiFePO₄ you don't have to worry about over-discharging the battery.
LiFePO₄ battery is inherently safer than NCM batteries in its greater thermal and chemical stability, making it less prone to explosions or fires. Ideal for home use and off-gird living.
FOSSiBOT LiFePO₄ batteries live up to 5000 cycles at 80% depth of discharge. Say you use 4KWh a day on a 2000Wh power station with solar panels hooked, NCA/NMC battery holds almost a year with 2 cycles a day while the lithium iron phosphate battery offers you at least 4 years.
The energy density of LiFePO₄ has now reached 160Wh/kg from previous 90 Wh/kg in just few years and will be expected to exceed 180Wh/kg that NCM packs own in future.
