To meet the growing demand for high energy density and power density in Li-ion batteries (LIBs) for electric vehicle (EV) applications (particularly in EVs offering a long driving range of 400–700 miles), production of lower cost, higher energy density cells is critically needed.
Theoretical energy density above 1000 Wh kg −1 /800 Wh L −1 and electromotive force over 1.5 V are taken as the screening criteria to reveal significant battery systems for the next-generation energy storage. Practical energy densities of the cells are estimated using a solid-state pouch cell with electrolyte of PEO/LiTFSI.
Energy density of batteries experienced significant boost thanks to the successful commercialization of lithium-ion batteries (LIB) in the 1990s. Energy densities of LIB increase at a rate less than 3% in the last 25 years . Practically, the energy densities of 240–250 Wh kg −1 and 550-600 Wh L −1 have been achieved for power batteries.
Electrode Engineering can reduce battery cost and improve energy density simultaneously by reducing the relative weight of inactive components such as conductive additive, binder, separator, and current collector. Another approach is using active materials with higher energy densities.
[ 3] Despite the increasing market share, state-of-the-art Li-ion batteries are approaching their theoretical limit for energy density and are now challenged by the demanding requirements of the emerging electric vehicles (EVs) and grid-energy storage sectors. [ 4, 5] Electrification of transportation has become a global trend.
As a result, the intercalation battery is more realistic to achieve high energy densities in the near term. Though enormous challenges remain, the conversion battery is the long-term pursuing target for high energy densities because it has a higher theoretical limit. 7.2. Reactions in primary batteries
