Lithium-ion Cells: Nominal Voltage 3.6-3.7V

Component Specifications

Definition

Lithium-ion cells are advanced electrochemical energy storage components consisting of an anode (typically graphite), cathode (lithium metal oxides like NMC, LFP, or LCO), separator (polyolefin membrane), electrolyte (lithium salt in organic solvent), and current collectors. They operate through reversible intercalation/de-intercalation of lithium ions between electrodes during charge/discharge cycles, offering high energy density, low self-discharge, and no memory effect.

Working Principle

During charging, lithium ions de-intercalate from the cathode, travel through the electrolyte and separator, and intercalate into the anode structure. During discharging, the reverse process occurs, with electrons flowing through the external circuit to power devices. The electrochemical potential difference between electrodes creates the cell voltage.

Materials

Anode: Graphite, silicon composites, or lithium titanate; Cathode: Lithium cobalt oxide (LCO), lithium nickel manganese cobalt oxide (NMC), lithium iron phosphate (LFP), or lithium manganese oxide (LMO); Electrolyte: Lithium hexafluorophosphate (LiPF6) in organic carbonate solvents; Separator: Polyethylene/polypropylene microporous membrane; Current collectors: Copper foil (anode), aluminum foil (cathode); Housing: Aluminum or steel casing.

Frequently Asked Questions

What is the difference between lithium-ion cells and lithium-ion batteries?

Lithium-ion cells are individual electrochemical units, while lithium-ion batteries consist of multiple cells connected in series/parallel configurations with battery management systems (BMS) for voltage regulation and protection.

How should lithium-ion cells be stored for maximum lifespan?

Store at 40-60% state of charge in cool, dry environments (15-25°C) to minimize degradation. Avoid full discharge or prolonged storage at full charge.
