LiFePO4 Batteries: Transforming Carbon Emission Landscape
Energy Storage from Renewable SourcesLiFePO4 batteries are now widely used in energy storage systems for solar and wind power. These batteries can efficiently store excess energy during high production periods and release this energy during peak demand periods, helping to reduce reliance on fossil fuels for electricity generation and thus reducing carbon emissions.
Electrification of VehiclesDue to its high energy density, long cycle life and high safety, LiFePO4batteries are used in a wide range of vehicles. LiFePO4 batteries replace conventional internal combustion engines that emit greenhouse gases, thereby reducing transport-related carbon emissions.
Energy EfficiencyLiFePO4 batteries have high charge-discharge efficiencies, minimising energy loss during the storage and release of electricity. This efficiency translates into reduced energy waste and lower carbon emissions.
Extended Battery LifeCompared to other batteries, LiFePO4 has a longer lifespan (8 years on average and up to 20 years). Longer lifespan means that fewer LiFePO4 battery cells need to be manufactured and disposed of, thereby reducing the environmental impact and carbon emissions associated with battery production.

Weight and Size:
LiFePO4: Lightweight and compact. Weight ranges from 100 to 200 Wh/kg.
Lead-Acid: Heavier and larger compared to LiFePO4. Weight ranges from 30 to 50 Wh/kg.
Maintenance:
LiFePO4: Virtually maintenance-free.
Lead-Acid: Requires regular maintenance, including topping up with distilled water and checking specific gravity.
Environmental Impact:
LiFePO4: Considered more environmentally friendly. Does not contain hazardous materials.
Lead-Acid: Contains hazardous materials like lead and sulfuric acid, requiring careful handling and disposal.
Cost:
LiFePO4: Higher upfront cost, but lower overall cost of ownership due to longer lifespan and higher cycle life.
Lead-Acid: Lower upfront cost, but higher maintenance and replacement costs over time.
- What Is An LFP Battery?
- An LFP battery, also known as a lithium iron phosphate battery, is a type of rechargeable battery that belongs to the broader category of lithium-ion batteries. It uses a specific cathode material called lithium iron phosphate (LiFePO4) in its construction, which gives it its name.
- What Is tThe 48V LiFePo4 Battery's Minimum Discharge Voltage?
- The minimum discharge voltage for KET LiFePO4 (Lithium Iron Phosphate) batteries is 2.5 volts per cell. Going below this voltage can damage the battery and reduce its overall lifespan. That's why all KET LiFePO4 battery packs are equipped with an intelligent BMS, which has a function to prevent over-discharge. This way you don't have to worry about accidentally over-discharging the battery pack during use.
These are the minimum voltages for LiFePO4 cells, but in practice we use mainly battery packs, and the following are the minimum voltages for the four common KET packs:
12V-LiFePO4-Battery: 10V
12V-LiFePO4-Battery: 20V
12V-LiFePO4-Battery: 30V
12V-LiFePO4-Battery: 40V
- What Is The 48V LiFePo4 battery's Minimum Cell Voltage?
- The minimum discharge voltage for KET LiFePO4 (Lithium Iron Phosphate) batteries is 2.5 volts per cell.
- What Are 48V LFP Batteries Made Of?
- Here's a breakdown of the main components of LFP batteries:
Cathode (Positive Electrode): The cathode of an LFP battery is made of lithium iron phosphate (LiFePO4).
Anode (Negative Electrode): The anode of an LFP battery typically consists of carbon-based materials, such as graphite or carbon nanotubes.
Separator: The separator is a thin, porous membrane that separates the cathode and anode, preventing direct contact and short circuits.
Electrolyte: LFP batteries use a liquid or solid electrolyte that facilitates the movement of lithium ions between the cathode and anode during charge and discharge cycles.
Current Collectors: Current collectors are typically made of metal foils, such as aluminum or copper. They are used to collect and distribute the electrical current between the battery electrodes and external circuits.
Housing: The housing or casing of the battery is usually made of a durable and lightweight material, such as metal or plastic, to protect the internal components and provide structural integrity.
- What Is The LiFePO4 Battery Cycles?
- LiFePO4 batteries typically have a cycle life range of over 2,000 cycles. If used properly and with good maintenance, it can even reach 5000 cycles of use.
- What Is The Lithium Iron Phosphate Battery Disadvantages?
- In the past, we talked more about the advantages of LiFePO4 batteries. Today we'll talk about some of its disadvantages.
Lower energy density: Compared to other lithium-ion battery chemistries, LiFePO4 batteries have a lower energy density.
Limited high-speed performance: LiFePO4 batteries are difficult to provide high current in a short period of time.
Higher self-discharge rate: Compared to some other lithium-ion chemistries, LiFePO4 batteries tend to have a higher self-discharge rate.
Limited voltage range: The nominal voltage of LiFePO4 is typically 3.2 V. This low voltage results in the need for more cells to achieve the required voltage, which increases the overall size and weight of the battery pack.
Higher cost: The production process for LiFePO4 batteries involves the use of more expensive raw materials and more complex manufacturing techniques, which results in a higher price.
Of course the advantages of LiFePO4 batteries' long cycle life, safety and stability have outweighed its disadvantages. This is why it is widely preferred.
- What Is The 48V LiFePO4 Battery's Temperature Range?
- The recommended temperature range for operating and storing Lithium Iron Phosphate (LiFePO4) batteries is generally between -20°C to 60°C (-4°F to 140°F). It's important to keep the battery within this range to ensure optimal performance, safety, and longevity.
We should also noting that extreme temperatures, especially high temperatures, can accelerate the aging process of LiFePO4 batteries and may lead to capacity loss or even permanent damage.
- What Is The 48V Lifepo4 SOC (State of Charge ) Voltage Chart?
-
The following is the State Of Charge Voltage Chart of a 48V LiFePO4 battery pack at a discharge rate of 0.5C and 2525℃ (77°F), as demonstrated by KET's engineers.
- What Is The LiFePO4 Battery's Max Charge Voltage?
- The maximum voltage for KET LiFePO4 batteries is 3.65V per cell. The following is the max voltage of some common KET LiFePO4 Battery Pack:
12V-LFP-Battery: 14.6V
24V-LFP-Battery: 29.2V
36V-LFP-Battery: 43.8V
48V-LFP-Battery: 58.4V
When this voltage is exceeded, the battery is overcharged. Overcharging can cause damage to the battery and pose safety risks. So how can this be avoided?
KET has a BMS for each battery pack, and this BMS has very powerful functions. Not only does it prevent overcharging, it also prevents over-discharging, over-current, short-circuiting, etc. If you are not satisfied with these functions, our engineers can also help you to add customised BMS functions, such as adding communication protocols, temperature monitoring, etc. If you would like to know more, you can contact us right away. Our engineers will provide you with a professional solution within 24 hours.
