ماژول شارژر / دشارژر باتری های لیتیومی SY3500 دارای خروجی 5V 1A مناسب برای ساخت پاور بانک

Description:
The module is used for the charging of a single lithium battery or multiple lithium batteries in parallel, and the charging port can take power from the USB port.
Charging and discharging batteries is a chemical reaction, but Li-ion is claimed to be the exception. Battery scientists talk about energies flowing in and out of the battery as part of ion movement between the anode and cathode. This claim carries merits but if the scientists were totally right, then the battery would live forever. They blame capacity fade on ions getting trapped, but as with all battery systems, internal corrosion and other degenerative effects also known as parasitic reactions on the electrolyte and electrodes till play a role.
Lithium-ion operates safely within the designated operating voltages; however, the battery becomes unstable if inadvertently charged to a higher than specified voltage. Prolonged charging above 4.30V on a Li-ion designed for 4.20V/cell will plate metallic lithium on the anode. The cathode material becomes an oxidizing agent, loses stability, and produces carbon dioxide (CO2). The cell pressure rises and if the charge is allowed to continue, the current interrupt device (CID) responsible for cell safety disconnects at 1,000–1,380kPa (145–200psi).
The charge process can be intermittent, and Li-ion does not need saturation as is the case with lead-acid. This offers a major advantage for renewable energy storage such as a solar panel and wind turbine, which cannot always fully charge the battery. The absence of a trickle charge further simplifies the charger. Equalizing charger, as is required with lead-acid, is not necessary with Li-ion.
