Strategies for Rational Design of High‐Power Lithium‐ion Batteries

Abstract

Lithium‐ion batteries (LIBs) have shown considerable promise as an energy storage system due to their high conversion efficiency, size options (from coin cell to grid storage), and free of gaseous exhaust. For LIBs, power density and energy density are two of the most important parameters for their practical use, and the power density is the key factor for applications such as fast‐charging electric vehicles, high‐power portable tools, and power grid stabilization. A high rate of performance is also required for devices that store electrical energy from seasonal or irregular energy sources, such as wind energy and wave energy. Significant efforts have been made over the last several years to improve the power density of LIBs through anodes, cathodes, and electrolytes, and much progress has been made. To provide a comprehensive picture of these recent achievements, this review discusses the progress made in high‐power LIBs from 2013 to the present, including general and fundamental principles of high‐power LIBs, challenges facing LIB development today, and an outlook for future LIB development.

A Comparative Review of Metal Oxide Surface Coatings on Three Families of Cathode Materials for Lithium Ion Batteries

“…Promptly, all these three families have been extensively studied and efficiently utilized to the development of commercial Li-ion batteries. In almost all cases, layered materials are preferred in high-energy batteries [11,12], whereas spinels and olivines are desired in high-power batteries due to their low cost and long-life requirements, respectively [13,14]. Nevertheless, the lithium-insertion materials should satisfy several aspects including chemical stability, capacity, rate capability, toxicity, cost and safety.…”

“…To alleviate the strain‐induced particle cracking and to obtain high packing density, a rational structural design for layered transition metal oxides is needed for PIB cathodes. [ 17‐22 ] In the case of this, we draw inspiration from the lithium‐ion batteries (LIBs). For examples, Amine et al .…”

“…To alleviate the strain-induced particle cracking and to obtain high packing density, a rational structural design for layered transition metal oxides is needed for PIB cathodes. [17][18][19][20][21][22] In the case of this, we draw inspiration from the lithium-ion batteries (LIBs). For examples, Amine et al demonstrated that if a thick shell completely encapsulates the core, the structural deterioration during electrochemical cycling can be suppressed, which consequently enhances the LIB's cycle performance; [23] likewise, Yang et al also showed that the multilayered shells around the core improve the structural stability of LIBs due to the presence of void space between the layers that act as buffer zones to accommodate charge/discharge-induced changes in volume.…”

“…While for charging, it is indeed the reverse process as described above. Thus, during the charging and discharging period, the more Li + ions moving between the positive and negative electrodes, the greater the activity being generated and the higher the charge-discharge specific capacity [7]. As a consequence, such principle of electrochemical conversion has confirmed that suitable anode materials are now playing pivotal role in improving electrochemical performance of LIBs.…”
