How Do 12V Li-Ion Batteries Function?
12V Li-ion batteries operate through electrochemical reactions involving lithium ions moving between the anode (typically graphite) and cathode (often lithium cobalt oxide or lithium iron phosphate) during charging and discharging cycles.Charging Process:
- During charging, lithium ions move from the cathode to the anode through the electrolyte.
Discharging Process:
- When discharging, the process reverses, allowing lithium ions to flow back to the cathode, generating electrical power.
