These batteries are intricate assemblies, comprised of several key components, each playing a vital role in the overall function of the battery:
The cathode is a critical component, responsible for one half of the battery's chemical reactions during charging and discharging.
It's typically crafted from materials like lithium cobalt oxide, lithium iron phosphate, or various other lithium-based compounds, depending on the specific battery chemistry.
On the flip side, the anode plays an equally crucial role in the battery's operation.
It's constructed from materials such as graphite, silicon, or lithium titanate.
During charging and discharging, the anode stores and releases lithium ions, forming the other half of the electrochemical process.
Acting as the conductive bridge between the cathode and anode, the electrolyte is a lithium salt dissolved in a solvent.
This solution facilitates the flow of lithium ions back and forth between the two electrodes, enabling the battery to store and release electrical energy efficiently.
The separator is a porous membrane strategically placed between the cathode and anode.
Its primary role is to prevent direct contact between these two electrodes while allowing the unhindered passage of lithium ions.
This separation is vital for the battery's safety and functionality.
To complete the circuit, conductive materials like copper are employed for the anode and aluminium for the cathode.
These current collectors ensure the flow of electricity within the battery.
