Applications of Lithium-Ion Batteries

Material Handling Equipment

Forklifts, pallet trucks, and other material handling equipment benefit greatly from the efficiency and reliability of lithium batteries. These batteries provide consistent power output, essential for demanding tasks in warehouses and manufacturing plants.

Uninterruptible Power Supplies (UPS)

In critical industrial environments, maintaining a continuous power supply is vital. These batteries are increasingly used in UPS systems to ensure that essential operations remain unaffected by power outages.

AGV
Renewable-Energy-Storage

Automated Guided Vehicles

AGVs are becoming more prevalent in the logistics and manufacturing industries. Lithium-ion batteries provide these vehicles with a reliable and long-lasting power source, enabling them to operate efficiently over extended periods.

Renewable Energy Storage

As industries move towards sustainable energy solutions, lithium-ion technology is crucial in storing energy from renewable sources like solar and wind. This stored energy can power industrial operations, reducing reliance on conventional power sources.

 

Lithium-ion Battery Structure

Cathode: The cathode of a lithium-ion battery is typically made of a lithium metal oxide, such as lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), or lithium iron phosphate (LiFePO4).
The choice of cathode material influences the performance characteristics of the battery.


Anode: The anode is usually composed of graphite. During discharge, lithium ions move from the anode to the cathode through the electrolyte, and during charging, they move back to the anode.

Electrolyte

The electrolyte is a conductive medium that allows the flow of lithium ions between the cathode and anode.
It is typically a lithium salt dissolved in a solvent.

Separator

The separator is a permeable membrane that keeps the cathode and anode apart to prevent a short circuit while allowing the passage of lithium ions.

Rechargeability

One of the key advantages of lithium-ion batteries is their rechargeability.

 

Battery balancing process

 

 

Detection: Detect the voltage, current, temperature and other parameters of each battery cell in the battery pack through the BMS.


Judgment: Determine whether there are differences between battery cells and the degree of difference based on the detection results.


Perform balancing: Select the appropriate balancing method based on the judgment results and perform the balancing operation. For active balancing, it may be necessary to accurately calculate the amount of energy transfer through the control algorithm; for passive balancing, it may be necessary to control the on and off time of the switch to consume excess energy.


Monitoring: Continuously monitor the parameter changes of battery cells during the balancing process to ensure the effectiveness and safety of the balancing operation.


End balancing: When the difference between battery cells reaches the set threshold, the balancing operation is ended.

 

FAQ

 

Q: Can I order samples of lithium-ion batteries?

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
