The applications of lithium-ion batteries (LIBs) have been widespread including electric vehicles (EVs) and hybridelectric vehicles (HEVs) because of their lucrative characteristics such as high energy density, long cycle life, environmental friendliness, high power density, low self-discharge, and the absence of memory effect [, , ].
Lithium-ion batteries (LIBs) have long been considered as an efficient energy storage system on the basis of their energy density, power density, reliability, and stability, which have occupied an irreplaceable position in the study of many fields over the past decades.
The theoretical energy density of lithium-ion batteries can be estimated by the specific capacity of the cathode and anode materials and the working voltage. Therefore, to improve energy density of LIBs can increase the operating voltage and the specific capacity. Another two limitations are relatively slow charging speed and safety issue.
Due to the presence of irreversible side reactions in the battery, the CE is always less than 100%. Generally, modern lithium-ion batteries have a CE of at least 99.99% if more than 90% capacity retention is desired after 1000 cycles . However, the coulombic efficiency of a battery cannot be equated with its energy efficiency.
What actually limits the energy density of lithium-ion batteries? The chemical systems behind are the main reasons. Cathode and anode electrodes are where chemical reactions occur. The energy density of a single battery depends mainly on the breakthrough of the chemical system.
