Lithium iron phosphate (LiFePO4), also called LFP, is one of the extra just lately-developed rechargeable battery chemistries and is a variation of lithium-ion chemistry. Rechargeable lithium iron phosphate batteries use LiFePO4 as the principle cathode material. Regardless of having a lower vitality density than different lithium-ion chemistries, lithium iron phosphate batteries can provide higher power density and longer life cycles.

Lithium-Ion

Lithium-ion can include two different chemistries for the cathode, lithium manganese oxide or lithium cobalt dioxide, as each have a graphite anode. It has a specific power of 150/200 watt-hours per kilogram and a nominal voltage of 3.6V. Its cost price is from 0.7C as much as 1.0C as larger costs can considerably damage the battery. Lithium-ion has a discharge fee of 1C.

BSLBATT is your premier LiFePO4 battery assembler. We manufacture customized lithium iron phosphate battery packs and assemblies for many functions. Our battery design crew uses the newest mechanical and electronic design tools to optimize the reliability, security, and manufacturability of your customized LFP battery packs. Our lithium iron phosphate batteries provide your battery-powered merchandise with cost-efficient and reliable rechargeable power.

As a consequence of its excessive energy density, this expertise is utilized in medium-energy traction applications (robotics, AGV, E-mobility, final-mile delivery, and so forth.) or heavy-responsibility traction purposes (marine traction, industrial vehicles, etc.)

The lengthy service life of the LFP and the potential of deep cycling make it attainable to use LiFePO4 in power storage applications (stand-alone purposes, Off-Grid methods, self-consumption with battery) or stationary storage normally.

Main benefits of Lithium Iron Phosphate:

● Very protected and safe expertise (No Thermal Runaway)

● Very low toxicity for the environment (use of iron, graphite, and phosphate)

● Calendar life > 10 ans

● Cycle life: from 2000 to a number of thousand (see chart below)

● Operational temperature vary: up to 70°C

● Very low inside resistance. Stability and even decline over the cycles.

● Constant power throughout the discharge vary

● Ease of recycling

● Life-cycle Lithium Iron Phosphate expertise (LiFePO4)

Lithium Iron Phosphate expertise is that which allows the greatest variety of cost/discharge cycles. That’s the reason this know-how is primarily adopted in stationary vitality storage methods (self-consumption, Off-Grid, UPS, etc.) for purposes requiring long life.

Sturdiness, Reliability, and price Effectiveness

Battery life is defined by the number of charge/discharge cycles a battery can survive.

Some testing has proven that lithium iron phosphate batteries can final about 2,000 expenses/discharge cycles, compared to perhaps 1,000 for lithium-ion batteries. These assessments go to the point where the batteries hold noticeably less charge, fairly than testing to some extent of utter failure.

The first downside with lithium cells is their degradation. Over time a lithium-ion cell will lose capability, with a complete lifetime of 2-three years. The exact lifetime is a perform of the amount of use, the amount discharged between recharging and different elements such because the temperature of the cells.

Notice: The discharge fee of a Li-ion battery retains growing over time as compared to Li-iron.

Lengthy life, slow discharge fee, and less weight must be basic options of a day by day use battery which is when a lithium-ion battery is appreciated because it is anticipated to have a longer “shelf life” than a Li-ion.

When not in use, a battery should not lose its charge at a quicker price. It ought to ship virtually the identical efficiency if using after a 12 months or so. This so-known as shelf life is around 350 days for lithium-iron and about 300 days for a lithium-ion battery.

Cobalt is dearer than the iron and phosphate utilized in Li-iron. So the lithium-iron-phosphate battery prices less (safer materials make it inexpensive to manufacture and to recycle) to the patron than the lithium-ion battery.

What’s New:

To offer your online business these advantages, our R&D department has developed a brand new energy supply that’s more stable, dependable and is eco-friendly constructed with lithium iron phosphate (LiFePO4). We are getting ready to launch. Would you wish to know extra?
