How do lithium-ion batteries work?

[Evelyn]

With many advantages such as high energy density, long cycle life, low self-discharge, no memory effect and environmental friendliness, lithium-ion batteries (LIBs) have been widely used in consumer electronics, such as smartphones, smart bracelets, digital cameras and laptops, with the strongest consumer demand. At the same time, it is promoted in the markets of pure electric, hybrid electric and extended-range electric vehicles, with the fastest market share growth. 

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 and has many micropores. The lithium ions reaching the negative electrode are embedded in the micropores of the carbon layer. The more lithium ions are embedded, the higher the charging capacity. Likewise, when the battery is discharged, the lithium ions embedded in the carbon layer of the negative electrode come out and move back to the positive electrode. The more lithium ions returned to the positive electrode, the higher the discharge capacity.

For example, ETEKWARE's deep-cycle lithium marine batteries are manufactured with high-quality materials, and these batteries are lightweight, durable, and maintenance-free. ETEKWAE supplies lithium-ion marine battery 480 not only for cranking or starting the boat's main engine, but also for trolling motors and electronic accessories.
