“…The Coulombic efficiency, the resistance, the long-term stability and the capacitance are only some of the parameters, which are influenced by the pre-lithiation degree. It could be shown that the optimal degree of pre-lithiation for LICs, using graphite as negative electrode, is between 70-80% [42,159]. However, it was also shown that the mass ratio between positive and negative electrode influences the optimal degree of pre-lithiation.…”

Abstract:In order to meet the sophisticated demands for large-scale applications such as electro-mobility, next generation energy storage technologies require advanced electrode active materials with enhanced gravimetric and volumetric capacities to achieve increased gravimetric energy and volumetric energy densities. However, most of these materials suffer from high 1st cycle active lithium losses, e.g., caused by solid electrolyte interphase (SEI) formation, which in turn hinder their broad commercial use so far. In general, the loss of active lithium permanently decreases the available energy by the consumption of lithium from the positive electrode material. Pre-lithiation is considered as a highly appealing technique to compensate for active lithium losses and, therefore, to increase the practical energy density. Various pre-lithiation techniques have been evaluated so far, including electrochemical and chemical pre-lithiation, pre-lithiation with the help of additives or the pre-lithiation by direct contact to lithium metal. In this review article, we will give a comprehensive overview about the various concepts for pre lithiation and controversially discuss their advantages and challenges. Furthermore, we will critically discuss possible effects on the cell performance and stability and assess the techniques with regard to their possible commercial exploration.

“…of the material, which is bound to increase the diffusion resistance of lithium ion. As a result, the rate performance of layered graphite negative electrode is poor, which limits its application in high power battery (Kumagai et al, 2015;Libich et al, 2017;Dagger et al, 2018;Mazur et al, 2019). Therefore, improving the capacity and rate performance of carbon anode materials is an important issue to be solved urgently at present.…”

In order to develop new type of carbon anode material with high performance, a novel organic carbon material polyacrylonitrile (PAN) hard carbon was prepared by calcination of polypropylene cyanide at 1,050 • C. The obtained PAN hard carbon is used as the negative electrode material of lithium ion battery, showing an initial capacity of 343.5 mAh g −1 which is equal to that of graphite electrode (348.6 mAh g −1 ), and a higher initial coulomb efficiency of 87.9% than that of graphite electrode (84.4%). Moreover, the PAN hard carbon electrode shows superior cycle stability and rate performance at different current rates. The charge capacities are 320.1, 219.0, 212.9, and 123.5 mAh g −1 at current rates of 0.2, 1, 2, and 3 C, with coulombic efficiencies of 98.1, 100.6, 88.1, and 110.0%, respectively, which are higher than those of graphite electrode (83.8, 97.6, 98.8, and 94.1%). In addition, the charging capacity of PAN hard carbon electrode can still remain at 284.3 mAh g −1 (0.2 C after 200 cycles), 226.4 mAh g −1 (1 C after 300 cycles), 149.5 mAh g −1 (2 C after 400 cycles), and 120.0 mAh g −1 (3 C after 100 cycles), with capacity retention rates of 78.2, 111.9, 79.7, and 88.6%, respectively. The capacity and capacity retention rate after cycling are significantly higher than those of graphite electrode, indicating that the PAN hard carbon electrode shows superior rate performance, which would provide a new idea for the development of novel negative electrode material with high performance.
