Lithium Battery Raw Materials Test Video
VTCBATT has its own lithium battery raw materials physicochemical testing laboratory, ensuring premium quality and reliability in modern lithium battery manufacturing. All the materials includes separators and electrodes to electrolytes and conductive materials — undergoes rigorous physical and chemical analysis.
Basic Component and How They Work
Several core parts are needed when making a lithium battery. When you charge the battery, lithium ions shift from the cathode to the anode. When the battery discharges, the ions return through the electrolyte circuit. Thus, creating electric current that powers your device. Below are the basic components of a battery.
It is a positive electrode where lithium ions end up when the battery is discharged.
This is a negative electrode where lithium moves when the battery is being charged.
Electrolyte is a special liquid or gel that lets lithium ions move between cathode and anode.
A porous sheet that keeps the cathode and anode from touching while allowing ions to pass.
Choosing the Right Material for Each Component
Here are our typical material choices for each battery component. Materials decide how well it works, how long it lasts, and how safe it is.
- Lithium Cobalt Oxide to ensure good energy density
- Lithium Iron Phosphate for a safer and long-lasting battery
- Nickel-Manganese-Cobalt for a balanced option
- Graphite ensures high conductivity and stability
- Silicon-graphite for a higher capacity
Often made from lithium salt mixed in organic solvents so ions can flow efficiently.
Pole Piece Manufacturing Process
Manufacturing the Battery Cell
Once the materials are ready, the following main steps are performed under strict conditions.
Mixing the active materials with binders and conductive additives to form a paste. Then, it is coated with metal foils that includes copper for anode and aluminum for cathode.
It is a process where solvents are removed and electrodes are flattened so they are uniform in thickness.
It involves cutting the large foils into strips of the correct size.
It involves stacking or winding. Putting together the cathode, anode, and separator into a cell format.
Injecting electrolyte under vacuum or controlled moisture environment. Then sealing the cell tightly.
Charging and discharging cycles under controlled conditions to activate the battery materials and stabilize the performance.
Each cell is checked for capacity, voltage, internal resistance, leakage, and safety before moving forward.
Building the Battery Pack
Choosing cells with similar voltage and capacity so the pack behaves evenly.
Adding electronics that monitor charge, discharge, temperature, and protect against problems like over-charge or over-discharge.
Enclosing the cells with protective housing, wiring, insulation, connectors, and protection against moisture, heat, etc.
Once assembled, the battery pack is tested as a whole for performance, safety, durability, and environmental conditions.
Quality and Safety Testing
To make sure our batteries are reliable, we run many safety and performance tests such as:
- Testing how much charge a battery holds and how it delivers power
- Verifying that the battery can safely handle physical stress, short circuits, impacts, or other hazards
- Checking for material and chemical consistency to avoid defects
- Ensuring battery maintains performance over many cycles
