Wholesale Lifepo4 Battery Suppliers
Lithium iron phosphate (LiFePO4) batteries are more expensive up front but they last much longer and require no maintenence. They’re also lighter than lead acid batteries.
These batteries have many advantages over lithium ion, including a long lifespan, high safety, low cost of ownership, and a low self-discharge rate.
High Energy Density
A battery’s energy density measures its power capacity in relation to its weight. It’s a crucial aspect for batteries used in mobile devices or in electric vehicles, where space is limited. High energy density allows for longer runtimes in a smaller footprint than batteries with lower energy density.
CATL’s lithium iron phosphate, or LFP, batteries have an energy density of 90-160 Wh/kg. This is a little lower than cobalt batteries, but still high by lithium ion standards. They use a lithium iron phosphate cathode and graphite electrode combined with a metallic backing for the anode.
The energy density of a battery depends on the ratio of elements used in the cell, as well as the production technology and foil thickness. For example, nickel is more energy-dense than cobalt, but it’s also unstable. Lithium nickel manganese cobalt, or NMC, batteries, combine the energy density of cobalt with the stability of nickel to create a battery that’s more versatile.
Long Lifespan
Depending on frequency and amount of use, lifepo4 batteries can last for up to 6 years. However, this doesn’t mean that they will not eventually deteriorate after a number of cycles. Like other lithium ion batteries, they are not designed to become inoperable once they reach their cycle life, but instead will simply have reduced storage capacity.
When it comes to the lifespan of a lithium iron phosphate battery, there are many factors that can influence it. The most important factor is correct battery maintenance. This Wholesale lifepo4 battery includes regular charging and avoiding extreme overcharging. It’s also important to store your batteries properly to extend their lifespan.
GWL/Power uses lithium iron phosphate batteries for backup power systems and solar energy setups because they have longer cycle life, higher energy density, and superior safety over traditional lead acid or AGM battery technology. Many manufacturers give a basic specification of 2000 charge cycles, but this isn’t a guarantee – manufacturers often give estimates that are much higher.
High Safety
Lithium iron phosphate batteries (LiFePO4) are the safest lithium battery type and are the most eco-friendly. They have no risk of thermal runaway like other lithium-ion chemistries, which can cause fires or explosions. These batteries also have a lower energy density decline with age compared to other lithium-ion chemistries, so they last longer.
They also have less risk of corrosion, and they do not release dangerous gasses when overheated or damaged. This means that they are safer to use in enclosed spaces, such as garages or sheds, although ventilation is still advisable.
Additionally, LiFePO4 batteries are made with recycled materials, which reduces the impact on the environment. This makes them a more sustainable choice than other lithium-ion batteries that use rare metals such as cobalt. These batteries are the perfect solution for off-grid solar systems, emergency backup power and other applications that require a high level of safety.
Low Cost of Ownership
The long life and high cycle count of LiFePO4 batteries result in a lower cost of ownership compared to lead acid and AGM batteries. This is due to fewer battery replacements over the lifetime of the batteries, as well as reduced electricity costs for charging and maintenance.
These batteries are also a good choice for bass boats and other marine toys, solar energy systems, RVs and golf carts, as they can operate in extreme temperatures that would degrade lead-acid batteries. They also don’t require the float charge stage that many other lithium batteries do, and they recharge in a fraction of the time that it takes for lead acid or AGM batteries.
In addition, the Lithium Iron Phosphate battery has a very low environmental impact, as it doesn’t contain cobalt or nickel, which are scarce and expensive metals. This makes it the ideal choice for an environmentally conscious consumer looking for a safe and durable power solution.
Low Self-Discharge Rate
Compared to nickel cadmium and lead acid batteries, lithium-ion batteries have the lowest self-discharge rate. This means that they retain more of their charge when not in use. However, it’s still important to know that lithium batteries do lose some of their capacity while in storage.
This is due to the natural aging process of the SEI film that protects the negative electrode in the battery. As this film ages, it develops loopholes that allow the positive and negative electrodes to contact each other. This causes side reactions that deteriorate the capacity of the battery.
This is why it’s important to take care of your battery and store it in a cool place when not in use. This will help to reduce the amount of self-discharge that occurs over time. It’s also a good idea to check the battery regularly to ensure that it is still in good condition.
Low Environmental Impact
When it comes to environmental impact, LiFePO4 batteries have a lower footprint than other lithium-ion battery chemistries. This is due to their slower decline in energy density over time (and a higher calendar-life), as well as the fact that they don’t emit gases such as lead or hydrogen.
Another benefit is the lower environmental impact of the raw materials used to produce this type of battery. Cobalt, the raw material for traditional Li-ion batteries, is a limited Wholesale lifepo4 battery resource that has been linked to health concerns and human rights violations at the mines where it’s extracted.
Current recycling methods involve smelting spent batteries at high temperatures to recover the precious metals within them. This process is incredibly energy-intensive, compounding the hidden carbon cost of EVs during their construction. Developing an alternative method of direct recycling for Li-batteries would help reduce the need to extract new raw materials and reduce waste.
