LiFePO4 batteries VS lithium-ion batteries

The difference between LiFePO4 batteries and general lithium-ion batteries and lead-acid batteries is very important. Reading this article can help you learn more about LiFePO4 batteries!

What are LiFePO4 Batteries?

LiFePO4 battery (LFP) is a lithium battery made of lithium iron phosphate as cathode material, graphite carbon electrode and metal backing as anode, and it is also the best lithium battery discovered by humans. Other types of lithium batteries include: lithium cobalt oxide (LiCoO22), lithium nickel manganese cobalt oxide (LiNiMnCoO2), lithium titanate (LTO), lithium manganese oxide (LiMn2O4), lithium nickel cobalt aluminum oxide (LiNiCoAlO2).

LiFePO4 is a natural mineral of the olivine family (triphylite). It was later discovered by Arumugam Manthiram and John B. Goodenough and used in the development of lithium-ion battery materials. In 1996, Padhi et al identified LiFePO4 as a polyanionic cathode material for batteries.

Application of LiFePO4 battery

Due to its low cost, non-toxicity, natural abundance of iron, excellent thermal stability, safety properties, electrochemical performance and specific capacity, LiFePO4 batteries have been widely praised and widely used in households, ships, solar systems, golf Caddy, AGV & AMR, etc.

LiFePO4 batteries have emerged as a new generation of sustainable deep cycle batteries to replace lead-acid batteries. As a new energy has very broad prospects.

LiFePO4 battery vs Li-ion battery

LiFePO4 batteries are not suitable for wearable devices such as watches. Compared to other lithium-ion batteries, they have a relatively low energy density and more than 4 times the cycle life of other lithium-ion batteries.

Most importantly, LiFePO4 batteries can not only achieve 3,000-5,000 cycles or more. They can also reach 100% depth of discharge (DOD). This represents overdischarge that you don’t have to worry about.In addition, it has a lifespan of up to 10 years, up to 7,000 cycles under ideal conditions. So LiFePO4 batteries are more suitable for applications such as solar systems, RVs, golf carts, marine and scooter, which is why it is by far the best.

Why do I choose LiFePO4 batteries over other batteries

Safe & stable & sustainable development

Safety is deeply felt by everyone who uses batteries. < “exploding” lithium-ion laptop batteries> clearly shows that.

LiFePO4 batteries have better thermal and structural stability. This is something that lead acid and most other battery types don’t have.LiFePO4 is incombustible. It can withstand high temperatures without decomposing. It is less prone to thermal runaway and stays cool at room temperature. It also won’t catch fire or explode if you insist on exposing it to heat or something dangerous like a short circuit or bump, depending on how naughty you are of course.

Sustainability – Deep Cycle

As rechargeable batteries, LiFePO4 batteries are concerned about their eco-friendliness, unlike lead-acid and lithium nickel oxide batteries, they are non-toxic, non-leak and can be recycled. LiFePO4 batteries have more than 10 times the cycle times compared to lead-acid batteries, which means you have a longer usage time.

Superior performance & easy management

Maybe you are often annoyed by the long charging time of the battery, but if you use LiFePO4 batteries, you don’t need to worry about these, LiFePO4 batteries can be guaranteed to be fully charged within 2h or less.

When not in use, lead-acid batteries generally have a monthly self-discharge rate of 30%, LiFePO4 batteries only 2%, and the running time is much higher than other batteries (including lithium-ion batteries)

The issue of weight and size is probably a significant factor for someone who uses batteries a lot as it determines whether I can make room for my scooter, boat, RV or industrial application without adding weight, which Very important.

Here I can tell you very clearly that the reason why LiFePO4 batteries are the best used by people is that it is nearly 50% lighter than lithium manganate batteries. It is 70% lighter than lead-acid batteries. LiFePO4 battery compared to sealed lead acid (SLA), LiFePO4 battery capacity is independent of discharge rate and provides constant power throughout the discharge process.

Understanding AGM Batteries vs Deep Cycle Batteries

Among the deep cycle batteries, rechargeable lead-acid batteries come in many types and are often used to start the vehicle and operate as an engine, as well as for emergency lighting. AGM batteries have been around since the 1980s, and perhaps most people don’t know what AGM stands for. In this issue, we will discuss what is special about AGM batteries and how to use our AGM batteries reasonably!

What does DOD stand for in a battery?

As a battery pack that stores electricity, it can provide power sources for a variety of needs, including solar energy, wind energy, powered cars, ships, drones, etc. When we buy batteries from merchants, we often encounter 80% DOD or 100% DOD marks, so what effect does it have on the batteries we use?
