What is a LiFePO4 battery?
A LiFePO4 (Lithium Iron Phosphate) battery, also known as a lithium-ion phosphate battery, is a type of rechargeable battery that belongs to the lithium-ion family. It is renowned for its high energy density, long cycle life, and improved safety compared to other lithium-ion battery chemistries. LiFePO4 batteries use a cathode material made of lithium iron phosphate (LiFePO4) and a carbon-based anode. The electrolyte, which allows the movement of lithium ions during charge and discharge, can be either a liquid or a solid polymer. (Read: What is Grade A LiFePO4 battery?)
What are the advantages of LiFePO4 batteries compared to other batteries?
LiFePO4 batteries offer several advantages over other battery chemistries. Firstly, they have a longer cycle life, lasting thousands of charge-discharge cycles, which translates to increased durability and cost-effectiveness. Secondly, LiFePO4 batteries are known for their enhanced safety, exhibiting higher thermal stability and lower risks of overheating or thermal runaway. Additionally, they have a higher tolerance for overcharging, reducing the chances of damage or failure. LiFePO4 batteries also feature fast charging capabilities and can be charged at higher currents without compromising their lifespan. Lastly, they perform well in a wide range of temperatures, making them suitable for various applications and environments. (Read: Advantages and Disadvantages of Lifepo4 Batteries: A Comprehensive Guide)
Are Lithium Batteries Safe?
Lithium batteries from Redway are safe and reliable. We use Lithium Ion Phosphate as our signature chemistry because it consists of no heavy metals or rare earth elements (such as cobalt), is nontoxic, doesn't contain lead or acid, is noncorrosive, doesn't emit gasses, requires no watering or maintenance, and will not explode or catch fire, unlike other lithium batteries. Moreover, a battery management system (BMS) microchip protects Redway Lithium batteries from overheating, overcharging, and short circuiting, thereby extending their lifespan and enclosing them in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so be careful not to submerge the battery underwater). For the best performance and reliability, we recommend using a LiFePO4 charger. (Read: Is Lithium Ion Battery Safer? and Lithium ternary batteries: are they safe?)
How do I get the longest battery life out of my LiFePO4 battery?
For longevity, it is important to top off LiFePO4 batteries after each use. Please do not fully discharge or overcharge them by leaving them connected to the charger after full charge. In the long run, the battery has a limited number of charge and discharge cycles, with one cycle being either the full charge and discharge cycle or a cumulative of both. (Read: How To Charge Redaway Power Lithium and Lifepo4 Batteries?)
How should I store my battery?
Before storing Redway Lithium batteries, they need to be kept in a cool, dry place, and fully charged. If Redway Lithium batteries are regularly recharged, they can be stored for an extended period of time. If you would like to learn more about storing Redway Lithium batteries, please refer to our article. (Read: Can you store LiFePO4 battery at 100%?)
How does a LiFePO4 battery work?
LiFePO4 (Lithium Ion Phosphate) batteries operate based on the principles of electrochemistry. They consist of an anode (positive electrode) made of carbon, a cathode (negative electrode) composed of lithium iron phosphate (LiFePO4), and an electrolyte that facilitates the movement of lithium ions. During charging, lithium ions are extracted from the cathode and stored in the carbon anode through a process called intercalation. This process reverses during discharge, where the stored lithium ions move back to the cathode, releasing electrical energy. The flow of electrons through an external circuit completes the electrical circuit and enables the battery to power devices. Recharging involves applying an external electrical current to drive lithium ions back to the cathode for future use. (Read: The voltage in an AAA battery – how does it work?)
Why does the battery stop working a few seconds after a high current draw?
If the load exceeds the continuous output current limit of the BMS, the pack will be shut down. It is important to make sure that the load does not exceed the BMS's continuous output current limit. Reset the battery by disconnecting the electrical load and troubleshooting your load and ensuring that the continuous current is not greater than the maximum continuous current. Please contact us if you require an additional current output for your battery. If your battery requires this, please contact us. (Click for more.)
Are the batteries waterproof?
A splash of water won't harm them, but they cannot be submerged completely. (Read: Are the LiFePO4 RV Batteries waterproof?)
Can you shut off or change the BMS board?
No, you cannot turn off the battery or change the BMS board. (Read: Can you shut off or change the BMS board?)
Will lithium batteries catch fire or blow up? I heard they are unsafe and a fire hazard.
It is possible for any battery to fail, sometimes catastrophically, or catch fire. Furthermore, lithium metal batteries are more volatile, do not recharge, and should not be confused with lithium-ion batteries. In their lithium-ion chemistry, Redway Lithium Batteries use lithium iron phosphate cells (LiFePO4), which have the highest thermal runaway temperature of all the different types of lithium batteries. It should also be noted that all lithium-ion batteries are subjected to UN testing before being shipped worldwide. Some lithium-ion chemistries are more volatile than others. (Read: Can lithium catch fire easily? and Can lithium batteries catch fire if not plugged in?)
Will the cost of Lithium batteries become cheaper?
Currently, lithium is about three to four times more expensive than lead-acid for the same capacity, but this will change as the supply of lithium increases around the world. (Read: Comparing Performance and Cost of LiFePO4 Prismatic Cells)
Can Redway Lithium batteries be fully discharged and then disposed of in the regular garbage?
When disposing of lithium batteries, it is vital to follow your applicable regulations. In many countries, it is forbidden to dispose of waste electronic equipment in standard waste containers. Keep only discharged batteries in a battery collection container. Cover battery connections with electrical tape or another approved covering to prevent short circuits. (Read: Can LiFePO4 RV Batteries be fully discharged and then disposed of in the regular garbage?)
Are LiFePO4 batteries environmentally friendly?
LiFePO4 (Lithium Iron Phosphate) batteries are considered to be more environmentally friendly compared to other battery chemistries. There are several reasons for this. Firstly, the materials used in LiFePO4 batteries, such as iron, phosphate, and carbon, are abundant and widely available. Secondly, LiFePO4 batteries do not contain toxic heavy metals like lead or cadmium, reducing the risk of environmental contamination during manufacturing, usage, or disposal. Additionally, LiFePO4 batteries have a longer lifespan, resulting in fewer battery replacements and reduced overall waste. Lastly, the recycling process for LiFePO4 batteries is relatively straightforward and efficient, allowing for the recovery of valuable materials and minimizing environmental impact. (Read: LiFePO4 Battery vs Lead-Acid Battery in Environmental Impact)
Can I use my lithium batteries in cold weather?
After the battery is warmed up, our 12V Lithium batteries can be charged.
Redway lithium batteries have built in cold weather protection - the battery cannot be charged if it is below -4℃ (24℉). There may be minor variations with tolerances on some parts. (Read: The Best Battery for Cold Weather Applications)
