What Is the Difference Between Lithium Battery and Lithium Ion Battery?

Nov. 13, 2020

Lithium Ion Battery 36vLithium batteries are disposable batteries, and lithium-ion batteries are rechargeable rechargeable batteries! Lithium-ion batteries generally use lithium cobalt oxide as the positive electrode and carbon as the negative electrode. The electrolyte is filled in between to form a channel for ion dissociation, and a separator is used to separate the positive and negative electrodes. Short circuit. When charging, due to the action of the electric field, lithium ions swim out of lithium cobalt oxide, free in the electrolyte, pass through the pores in the separator, and reach the negative electrode and react with carbon to form lithium carbide; the discharge process is opposite, and the lithium ions return to the positive electrode. It is the charging and discharging process of lithium-ion batteries.

Lithium batteries generally refer to primary lithium batteries, mainly lithium manganese and lithium iron batteries. Lithium-ion batteries are mainly lithium secondary batteries. The rechargeable batteries mainly include lithium manganese oxide, lithium cobalt oxide and lithium iron phosphate batteries. Lithium ion power batteries are mainly suitable for power batteries. The main feature is that the battery can High-power discharge, long battery cycle life, etc., such as lithium iron phosphate lithium ion battery. Lithium batteries use metal lithium as an electrode to generate electric current through electron transfer. Because they are prone to produce dendrites and cause explosions, they are no longer in use. Lithium batteries are primary batteries. Lithium-ion batteries are charged and discharged by the transfer of lithium ions, and mainly use lithium-doped metal oxides as electrodes.

Lithium Ion Battery 36V is a rechargeable secondary battery. 1. Lithium primary battery is also called primary lithium battery. It can be discharged continuously or intermittently. Once the electricity is exhausted, it can no longer be used, and it is widely used in low-power electronic products such as cameras. The self-discharge of lithium primary battery is very low and can be stored for 3 years. It will be better if stored under refrigerated conditions. It is a good way to store lithium primary batteries in a cold place. Note: Lithium primary batteries are different from lithium ion batteries. Lithium primary batteries cannot be recharged, and charging is very dangerous! Lithium battery principle--Lithium metal batteries Lithium metal batteries often use manganese dioxide MnO2 as the positive electrode material, and use metal lithium Li or its alloys As the negative electrode material, a battery using a non-aqueous electrolyte solution. The chemical equation of the discharge reaction is Li+MnO2=LiMnO2.

Rechargeable Li-ion Cells are also called secondary lithium batteries. It can be stored for more than half a year at 20°C. This is because its self-discharge rate is very low and most of its capacity can be recovered. Lithium battery principle-Lithium ion battery Lithium ion battery often uses lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and the battery using non-aqueous electrolyte solution. The chemical equation of the positive electrode when charging is LiCoO2==Li(1-x)CoO2+XLi++Xe- (electron), the chemical equation of the negative electrode is 6C+XLi++Xe- = LixC6, the total reaction of the battery is LiCoO2 when charging +6C = Li(1-x)CoO2+LixC6.

The self-discharge phenomenon of lithium batteries, if the battery voltage is kept below 3.6V for a long time, it will cause the battery to over discharge and destroy the internal structure of the battery and reduce the battery life. Therefore, long-term storage of lithium batteries should be recharged every 3 to 6 months, that is, charged to a voltage of 3.8 to 3.9V (the best storage voltage of lithium batteries is about 3.85V), and it is advisable to maintain the discharge depth at 40%-60% , Should not be full. The battery should be stored in a dry environment at 4℃~35℃ or in moisture-proof packaging. Keep away from heat sources and do not place in direct sunlight. Lithium batteries have a wide application temperature range. They can still be used outdoors in winter in the north, but the capacity will be much reduced. If they return to room temperature, the capacity can be restored.
