A lithium-ion capacitor (LIC) is a hybrid type of capacitor and is classified as a type of supercapacitor. Activated carbon is normally used as the cathode. The anode of the LIC consists of carbon material that is pre-doped with lithium ions. This pre-doping process reduces the anode potential and allows a relatively high output voltage compared to other supercapacitors.

In 1981, Dr. Yamabe of Kyoto University, in collaboration with Dr. Yata of Kanebo Co. created a material known as PAS (polyacene semiconductor) by pyrolyzing phenolic resin at 400-700 °C.[1] This amorphous carbonaceous material works well as an electrode in high energy density rechargeable devices. Patents were filed in the early 1980s by Kanebo Co.,[2] and efforts to commercialize PAS capacitors and lithium ion capacitors (LICs) began. The PAS capacitor was first used in 1986[3] and the LIC capacitor in 1991.

Researchers from the University of Oxford and the University of Seville have published a recent study in the journal Nature in which they define new strategies for the manufacture of a generation of more efficient and safer lithium-ion batteries. The aim is to overcome some of the limitations that these devices currently pose: their storage capacity and the contamination derived from some of the elements used to build them.

To do so, they have studied two types of cathodes that are very similar in composition, but have completely different behaviors: one of them suffers the well-known loss of energy density in the first cycle, and the other does not. «This difference in behavior is due to the formation in one of them of a new superstructure, i.e., a very particular arrangement of the metal atoms,» explains Juan Gabriel Lozano, a researcher at the School of Engineering of the University of Seville. This characteristic has been shown to prevent restructuring during the first charge-discharge cycle. «This result would allow us to overcome one of the main bottlenecks encountered so far in the development of this type of technology,» explains the researcher.

Lithium-ion batteries: characteristics

brines of closed basins (salars). Argentina has one of the largest reserves of lithium in salt flats, ranking fourth in world reserves, which are distributed in several salt flats in the Puna region (Catamarca, Salta and Jujuy). In this sense, Argentina is in a privileged position due to its natural resources, so it is convenient to create knowledge about the processes of synthesis and characterization of materials used in lithium-ion batteries,

air allowing to obtain a material with adequate discharge capacity. LiNi_0.5Mn_1.5O_₄ on the other hand, was obtained by replacing one quarter of Mn by Ni in the synthesis of LiMn_₂O_₄ with Φ = 1; 25, the material obtained was annealed at temperatures between 700 and 900 ΦC.

In chapter 1 the introduction and general considerations are documented, where basic information can be found to understand the methods of synthesis and characterization of each of the materials as well as the motivation to do this work. Chapter 2 gives a detailed description of the synthesis processes of each of the active materials, of the materials used as coatings and of the processes to coat the base materials, as well as a brief description of the synthesis methods used and of the fundamental principles of the morphological and electrochemical characterization techniques employed. Chapter 3 describes the morphological and electrochemical study of LiCoO_₂(LCO)_, NiO and LiAl_₅O_₈ (LAO) materials used as coatings and the coated materials named LCO@NiO and LCO@LAO.

Lithium-ion batteries are a type of rechargeable battery in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and from the cathode to the anode when charging. Lithium-ion batteries are very common in portable consumer electronics due to their high energy to weight ratio, lack of memory effect and slow loss of charge when not in use. In addition to consumer electronics, lithium-ion batteries are increasingly used in more defense, automotive and aerospace applications due to their high energy density.
