The price of lithium batteries is mainly related to the capacity of the lithium battery. Generally, 1 KWH costs around 1,200 yuan. You can estimate the cruising range and lithium battery capacity you need based on this ratio.
Lithium metal battery: basic principles of lithium battery Lithium metal battery generally uses manganese dioxide as the positive electrode material, lithium metal or its metal alloy as the electrode material negative and uses a non-aqueous electrolyte solution.
Discharge reaction: Li+MnO2=LiMnO2.

Protection measures:
Battery lithium Once the core is overcharged to a voltage above 4.2V, side effects will begin. The higher the overload voltage, the higher the risk. Once the cell voltage of the battlithium erie is greater than 4.2 V, the number of lithium atoms remaining in the positive electrode material is less than half. At this point, the storage cells often collapse, causing a permanent loss of battery capacity.
If charging continues, since the storage compartment of the negative electrode has been filled with lithium atoms, subsequent lithium metal will accumulate on the surface of the negative electrode material. These lithium atoms will grow dendrites from the surface of the negative electrode towards the lithium ions. These lithium metal crystals will pass through the separator and short circuit the positive and negative electrodes. Sometimes the battery explodes before a short circuit occurs.
