The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
What are Cathode and Anode for a lithium battery？ The negative electrode in a cell is called the anode. The positive side is called the cathode. During charging, the lithium ions move from the cathode, through the separator, to the anode. During discharge, the flow reverses.
For example, silicon-based materials, alloy materials, tin-gold materials, and the like. The negative electrode of lithium ion battery is made of negative electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled.
The negative electrode in a cell is called the anode. The positive side is called the cathode. During charging, the lithium ions move from the cathode, through the separator, to the anode. During discharge, the flow reverses. The most popular material used for the anode is graphite.
Simultaneously, the term “lithium-ion” was used to describe the batteries using a carbon-based material as the anode that inserts lithium at a low voltage during the charge of the cell, and Li 1−x CoO 2 as cathode material. Larger capacities and cell voltages than in the first generation were obtained ( Fig. 1 ).

The negative electrode of a discharging lithium-ion battery is the anode (see Section 3 of the ESI† and Fig. S2 for a discussion of electrode terminology; for brevity, we will mostly use "anode" for "negative electrode", and "cathode" for "positive electrode" in the following discussions of a discharging battery, as in most of the specialized literature). It consists of a ...
The cathode is the positive electrode, where reduction (gain of electrons) occurs, while the anode is the negative electrode, where oxidation (loss of electrons) takes place. During the charging process in a battery, electrons flow from the cathode to the anode, storing energy that can later be used to power devices
The high capacity (3860 mA h g −1 or 2061 mA h cm −3) and lower potential of reduction of −3.04 V vs primary reference electrode (standard hydrogen electrode: SHE) make the anode metal Li as significant compared to other metals [39], [40].But the high reactivity of lithium creates several challenges in the fabrication of safe battery cells which can be …
