About Pack lithium battery structure

Lithium batteries are divided into lithium batteries and lithium-ion batteries. Both mobile phones and laptops use lithium-ion batteries, commonly known as lithium batteries. Real lithium batteries are rarely used in daily electronic products because of their great danger. Figure. 1 Lithium.

Lithium-ion batteries use carbon materials as the negative electrode and lithium-containing compounds as the positive electrode. There is no lithium metal, only lithium-ion, which is.

Figure. 3 Positive electrode: active substance, conductive, solvent, adhesive, matrix. Figure. 4 When the battery discharges, the electron electrode is obtained from the external circuit, and the electrode is reduced at this time. It is usually a high.
