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.
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.
Overall, between 1991 and 2018, prices for all types of lithium-ion cells (in dollars per kWh) fell approximately 97%. Over the same time period, energy density more than tripled. Efforts to increase energy density contributed significantly to cost reduction.
1. Introduction Among numerous forms of energy storage devices, lithium-ion batteries (LIBs) have been widely accepted due to their high energy density, high power density, low self-discharge, long life and not having memory effect , .
In their initial stages, LIBs provided a substantial volumetric energy density of 200 Wh L −1, which was almost twice as high as the other concurrent systems of energy storage like Nickel-Metal Hydride (Ni-MH) and Nickel-Cadmium (Ni-Cd) batteries .
The latter battery has an energy density of 620 W·h/L. The device employed heteroatoms bonded to graphite molecules in the anode. Performance of manufactured batteries has improved over time.
