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.
Currently, the lithium-air battery has the highest theoretical energy density, at around 11,400 Wh/kg. However, this battery is still in the research and development stage and has not yet been commercialized. Among commercial batteries, the lithium-ion battery has the highest energy density, with some models reaching up to 265 Wh/kg.
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.
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
The energy density of AA batteries varies depending on the type of battery. Alkaline AA batteries, which are the most common type of AA battery, have an energy density of around 100-150 Wh/kg. Lithium AA batteries, on the other hand, have a much higher energy density, with some models reaching up to 300 Wh/kg.
Practical energy densities of the cells are estimated using a solid-state pouch cell with electrolyte of PEO/LiTFSI. Exploring alternative rechargeable batteries with energy densities above state-of-the-art lithium-ion batteries is the critical challenge for both academia and industry.
