The direction of movement of lithium electrons when charging a lithium battery is

When a lithium-ion battery is charged, the direction of movement of the lithium ions is: The lithium ions move from the positive electrode to the negative electrode.

When the battery power is connected and the lithium-ion battery is charged, the positive electrode loses electrons and the lithium ions escape from the crystal lattice of the positive electrode material , enter the electrolytic cell and pass through the separator and move towards the negative electrode, and at the same time reach the negative electrode. The lithium ions on the negative electrode are embedded in the negative electrode material, and the electrons also reach the negative electrode through the external circuit. of the negative electrode combine with the embedded lithium ions to form a lithium-carbon interlayer compound.

When the battery is discharged, the reverse process occurs. It can be seen that during the prIn the process of charging and discharging, the movement directions of lithium ions and electrons are consistent. The difference is that lithium ions recoil and. in the circuit. The electrons are transmitted through the external circuit.

Working principle:

Lithium metal batteries generally use manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the negative electrode material, and use a non-aqueous battery with electrolyte solution.

Discharge reaction: Li+MnO2=LiMnO2

Lithium-ion battery:

Lithium-ion batteries generally use metal oxide alloy lithium as cathode material and graphite. as cathode material. Negative electrode materials, batteries using non-aqueous electrolytes.

Thedirection of movement of lithium ions when charging a lithium ion battery is: from positive electrode to negative electrode.

A lithium-ion battery is a secondary battery (rechargeable battery) that relies primarily on the movement of lithium ions between positive and negative electrodes to function.

The charging and discharging process of lithium-ion batteries is the process of intercalation and deintercalation of lithium ions. When the battery is charged, lithium ions are generated on the positive electrode of the battery and the generated lithium ions move to the negative electrode via the electrolyte. Likewise, when the battery is discharged, the lithium ions embedded in the carbon layer of the negative electrode are released and return to the positive electrode.
