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.
This combination of two lithium insertion materials gives the basic function of lithium-ion batteries. More specifically, lithium ions are inserted into/extracted from a solid matrix without the destruction of core structures, so called topotactic reactions, in positive and negative electrodes during charge and the reverse process on discharge.
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
Graphite (C) has good conductivity, high specific capacity and low lithium impingement potential, graphite electrode has a suitable charge-discharge platform and cycle performance, so it is the most widely used anode of lithium-ion batteries.
Commercial lithium-ion battery binders have been able to meet the basic needs of graphite electrode, but with the development of other components of the battery structure, such as solid electrolyte and dry electrode, the performance of commercial binders still has space to improve.
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.
Nanotechnology of Positive Electrodes for Li-Ion Batteries
Taking into account the pre-factor of L2 in the second equation, we find that τ equals 9 h for 2 µm-particle size, reduced to 13 min for 100 nm-particle size. Therefore, faster charge process requires the fabrication of particles of smaller size, L < 100 nm, which is a very challenging technology at the industrial scale.
