Comprehensive Introduction to 12V Sheet Metal Cased Lithium Batteries

12V sheet metal cased lithium batteries are a common and widely used type of battery, playing a crucial role in numerous fields.

Structure and Principle

Working Principle: During charging, the external voltage causes the lithium ions in the positive electrode to deintercalate, flow through the electrolyte and across the separator, and intercalate into the negative electrode. At the same time, the electrons in the positive electrode also flow to the negative electrode through the external circuit, and the battery voltage continuously rises until it reaches the charging cut-off voltage. During discharging, the lithium ions deintercalate from the negative electrode, flow through the electrolyte and across the separator, and intercalate into the positive electrode again. The electrons in the negative electrode also flow to the positive electrode through the external circuit, and the battery voltage continuously decreases until it reaches the discharging cut-off voltage.

　　Fast Charging:It supports fast charging technology and can be fully charged in a relatively short time,saving a lot of charging time and facilitating users to use the device frequently.For example,some 12V lithium batteries can charge from 0 to 80%in 1-2 hours using a dedicated fast charger.

　　Low Self-Discharge Rate:Generally,it can be less than 1%per month,less than 1/20 of that of nickel-metal hydride batteries.This enables the battery to maintain a high power reserve even when not in use for a long time,reducing the trouble of frequent charging.The self-discharge rate comparison of common 12V batteries

　　Application Scenarios

　　1.Automotive Field:It can be used as the auxiliary power supply for hybrid and pure electric vehicles,powering the vehicle's electronic devices such as the audio system and in-vehicle computer.It can also be used as a starting battery.Compared with traditional lead-acid starting batteries,it has the advantages of light weight and long life.

　　Precautions

　　Charging:Choose a suitable charger and avoid using an incompatible charger to prevent overcharging or damage to the battery.When charging,place the battery in a well-ventilated and temperature-appropriate environment,and avoid charging in high-temperature,humid,or flammable environments.For example,a certain 12V lithium battery is recommended to use a charger with a charging voltage of 14.6V and a charging current not exceeding 100A.
