“…[84][85][86] By contrast, even the best commercial cathodes are limited to gravimetric capacities around 200 mAh/g. 85,87 The cell voltage is also limited by the choice of cathode. Thus, there has been intense interest in developing high-capacity, high-voltage cathodes to increase the specific energy of LIBs.…”

Reducing cost and increasing energy density are two barriers for widespread application of lithium-ion batteries in electric vehicles. Although the cost of electric vehicle batteries has been reduced by $70% from 2008 to 2015, the current battery pack cost ($268/kWh in 2015) is still >2 times what the USABC targets ($125/kWh). Even though many advancements in cell chemistry have been realized since the lithium-ion battery was first commercialized in 1991, few major breakthroughs have occurred in the past decade. Therefore, future cost reduction will rely on cell manufacturing and broader market acceptance. This article discusses three major aspects for cost reduction: (1) quality control to minimize scrap rate in cell manufacturing; (2) novel electrode processing and engineering to reduce processing cost and increase energy density and throughputs; and (3) material development and optimization for lithium-ion batteries with high-energy density. Insights on increasing energy and power densities of lithium-ion batteries are also addressed.

“…With the expanding applications of lithium-ion batteries in portable equipment, electric vehicles and power grids, conventional LiCoO 2 cathodes no longer suffice due to the scarcity of cobalt resources, so it is necessary to develop some new cathode materials [1]. To date, various materials including polyanionic compounds [2][3][4][5], layered [6] and spinel [7] metal oxides have been prepared as the substitute for LiCoO 2 .…”

“…TEMPO‐substituted polymers, which exhibit one‐electron and one‐step redox reactions, offer a specific capacity of approximately 100 mA h g −1 . This value is smaller than those of most conventionally used lithium metal oxides, such as LiCoO 2 (≈140 mAh g −1 ) . Multiple‐electron, multiple‐step redox reactions have been also examined extensively to improve the capacity beyond 200 mA h g −1 (or >1000 mA h g −1 , according to the concept of superlithiation) .…”

“…However, the typically observed fluctuating voltages that originate from multistep redox reactions are not ideal for batteries. From another perspective, the volumetric capacity of organic electrodes tends to be lower than those of inorganics, owing to the much lower density of organic compounds (1–2 g cm −3 ) compared with ceramics (3–6 g cm −3 ) . Bulky batteries are not useful in small electronic devices.…”
