12V 200Ah Lithium Iron Phosphate Battery For Energy Storage Power Supply Solar Landscape Lighting Lamps

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

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: Supports fast charging technology and can be fully charged in a relatively short time, saving a lot of charging time and facilitating frequent device use. Some 12V lithium batteries can charge from 0 to 80% in 1-2 hours using a dedicated fast charger.

Low Self-Discharge Rate: Generally less than 1% per month, which is less than 1/20 of nickel-metal hydride batteries. This enables the battery to maintain high power reserve even when not in use for long periods, reducing the need for frequent charging.

• Automotive Field: Used as auxiliary power supply for hybrid and pure electric vehicles, powering electronic devices such as audio systems and in-vehicle computers. Can also serve as a starting battery, offering advantages of light weight and long life compared to traditional lead-acid batteries.
• Energy Storage: Ideal for solar power systems, landscape lighting, and other renewable energy applications requiring reliable, long-lasting power storage.
