Lithium-ion batteries generally use lithium cobalt oxide as the positive electrode, carbon as the negative electrode, intermediate filling of the electrolyte to form ion-free channels, and separators to separate the positive and negative electrodes from short circuits. When charging, lithium ions migrate from the lithium cobaltate due to the electric field, and pass through the pores in the separator in the electro-hydraulic solution, and reach the negative electrode and react with carbon to form lithium carbide; in contrast, the lithium ion returns to the positive electrode. It is the charging and discharging process of a lithium ion battery.
Lithium battery generally refers to a primary lithium battery, mainly lithium manganese, lithium iron battery. Lithium-ion batteries are mainly lithium secondary batteries. Rechargeable batteries are mainly lithium manganate, lithium cobalt oxide and lithium iron phosphate batteries. Lithium-ion batteries are mainly suitable for power batteries. The main feature is that batteries can High-power discharge, long battery cycle life, etc., such as lithium iron phosphate lithium ion battery.
Lithium battery is made of metal lithium as an electrode, which generates current by electron transfer. It is not used because it is easy to cause dendrites to cause explosion. The lithium battery is a primary battery.
Lithium-ion batteries are charged and discharged by the transfer of lithium ions, mainly using oxides of lithium-doped metals as electrodes. The lithium ion battery is rechargeable for the secondary battery.
If the lithium battery is an indispensable organ of the lithium battery, the material of the lithium battery is the gene of the lithium battery, that is, the performance of the lithium battery, the material of the lithium battery plays a fundamental role.
