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
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.
LFP material The positive electrode material of LFP battery is mainly lithium iron phosphate (LiFePO4). The positive electrode material of this battery is composed of several key components, including:
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
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.
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
In the production process of LFP batteries, the anode material is one of the critical factors of battery performance. Among them, lithium carbonate, phosphoric acid, and iron are the three most vital raw materials for preparing LFP battery anode materials.
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
