Description
Technical Field
The utility model relates to a lithium battery test field, especially a battery accuse temperature explosion-proof equipment that charges.
Background
A lithium ion battery is a secondary battery (rechargeable battery) that mainly operates by movement of lithium ions between a positive electrode and a negative electrode. In the process of charging and discharging, Li + is inserted and extracted back and forth between the two electrodes; during charging, Li + is extracted from the positive electrode, and is inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state, whereas during discharging, the reverse is true.
Lithium batteries are classified into lithium batteries and lithium ion batteries. Lithium ion batteries are used in mobile phones and notebook computers, and are commonly called as lithium batteries. The battery generally adopts a material containing lithium element as an electrode, and is a representative of modern high-performance batteries. The real lithium battery is rarely applied to daily electronic products due to high danger.
The lithium ion battery takes a carbon material as a negative electrode and a lithium-containing compound as a positive electrode, no metal lithium exists, and only lithium ions exist, so that the lithium ion battery is formed. The lithium ion battery is a generic term for a battery using a lithium ion intercalation compound as a positive electrode material. The charge and discharge process of the lithium ion battery is the process of lithium ion intercalation and deintercalation. In the process of intercalation and deintercalation of lithium ions, intercalation and deintercalation of electrons equivalent to lithium ions are accompanied at the same time. Lithium ions are inserted/extracted and inserted/extracted back and forth between the positive and negative electrodes during charge and discharge, and are figuratively referred to as "rocking chair batteries".
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 through the electrolyte. The carbon as the negative electrode has a layered structure having many pores, and lithium ions reaching the negative electrode are inserted into the pores of the carbon layer, and the more lithium ions are inserted, the higher the charge capacity is. Similarly, when the battery is discharged (i.e., during our use of the battery), lithium ions embedded in the carbon layer of the negative electrode are extracted and move back to the positive electrode. The more lithium ions returned to the positive electrode, the higher the discharge capacity.
The charging current of the lithium battery is generally set between 0.2C and 1C, and the larger the current is, the faster the charging is and the more the battery generates heat. Also, excessive current charging, the capacity is not sufficient because the electrochemical reaction inside the battery takes time. Just like pouring beer, pouring too quickly can produce foam, which is otherwise not full.
18650 is a standard lithium ion battery model number, as determined by SONY corporation of Japan for cost savings in the year, where 18 denotes a diameter of 18mm, 65 denotes a length of 65mm, and 0 denotes a cylindrical battery.
The 18650 common batteries are classified into lithium ion batteries and lithium iron phosphate batteries. The voltage of the lithium ion battery is 3.7V in nominal voltage, 4.2V in charge cut-off voltage, the voltage of the lithium iron phosphate battery is 3.2V in nominal voltage, 3.6V in charge cut-off voltage, the capacity is usually 1200mAh-3350mAh, and the common capacity is 2200mAh-2600 mAh.
