In a real full battery, electrode materials with higher capacities and a larger potential difference between the anode and cathode materials are needed.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
According to the reaction mechanisms of electrode materials, the materials can be divided into three types: insertion-, conversion-, and alloying-type materials (Figure 1 B). 25 The voltages and capacities of representative LIB and SIB electrode materials are summarized in Figures 1 C and 1D.

However, these promising materials still suffer from some scientific problems and challenges that limit their further applications. For negative materials, lithium metal is the ultimate choice for the anode in an Li battery because of its highest theoretical capacity and lowest electrochemical potential.
Very often, it comes directly from the name of the positive electrode active material. To compare these options, the characteristics used in the previous figure are generally used (specific power, specific energy, cost, life, safety). For the battery life, two main characteristics are to be considered : Cycle life: aging in use.

The lithium-ion battery generates a voltage of more than 3.5 V by a combination of a cathode material and carbonaceous anode material, in which the lithium ion reversibly inserts and extracts. Such electrochemical reaction proceeds at a potential of 4 V vs. Li/Li + electrode for cathode and ca. 0 V for anode.
Therefore, this review is focused on a variety of positive electrode materials, such as transition metal oxides, metal sulfides, carbonaceous materials and other types of materials based on two main electrolyte systems, i.e., …
In general, an electrode is an electrical conductor which makes contact with a non-metallic part of a circuit. In a battery, the electrodes connect the battery terminals to the electrolyte. The electrode at the positive terminal is known as the cathode and the electrode at the negative terminal is known as the anode. Each electron is itself ...
