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.
We also consider additional performance characteristics including energy density and specific energy. When energy density is incorporated into the definition of service provided by a lithium-ion battery, estimated technological improvement rates increase considerably.
As space and weight in EVs are limited, the batteries with higher energy densities can drive vehicles a longer distance. LIBs have one of the highest energy densities (250–693 Wh/L and 100–265 Wh/kg) of current battery technology, but it is still significantly less that of gasoline.
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
As expected, (CF) n /Li battery has a high practical energy density (>2000 Wh kg −1, based on the cathode mass) for low rates of discharge (<C/10) . However, it is found that the power density of (CF) n /Li battery is low due to kinetic limitations associated with the poor electrical conductivity of (CF) n of strong covalency .
