In this review, we summarized the recent advances on the high-energy density lithium-ion batteries, discussed the current industry bottleneck issues that limit high-energy lithium-ion batteries, and finally proposed integrated battery system to solving mileage anxiety for high-energy-density lithium-ion batteries.
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.
This discovery could improve the performance and life expectancy of a range of rechargeable batteries. Lithium-ion batteries power everything from smart phones and laptops to electric cars and large-scale energy storage facilities. Batteries lose capacity over time even when they are not in use, and older cellphones run out of power more quickly.
It is concluded that the room for further enhancement of the energy density of lithium-ion batteries is very limited merely on the basis of the current cathode and anode materials. Therefore, an integrated battery system may be a promising future for the power battery system to handle the mileage anxiety and fast charging problem.
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.
The findings were published Sept. 12 in the journal Science. “We are helping to advance lithium-ion batteries by figuring out the molecular level processes involved in their degradation,” said Michael Toney, a senior author of the study and a professor of chemical and biological engineering at the University of Colorado.
The theoretical specific energy of Li-S batteries and Li-O 2 batteries are 2567 and 3505 Wh kg −1, which indicates that they leap forward in that ranging from Li-ion batteries to lithium–sulfur batteries and lithium–air batteries.

The culprit behind the degradation of lithium-ion batteries over time is not lithium, but hydrogen emerging from the electrolyte, a new study finds. This discovery could improve the performance and life expectancy of a range of rechargeable batteries.
Solid-state batteries have a more substantial environmental impact during the production phase, approximately 27 % higher than similar lithium batteries, with NCM outpacing LFP. However, in the usage phase, NCM batteries, due to their unique structure, significantly mitigate energy losses compared to LFP batteries.
Lithium-ion batteries unavoidably degrade over time, beginning from the very first charge and continuing thereafter. However, while lithium-ion battery degradation is unavoidable, it is not unalterable. Rather, the rate at which lithium-ion batteries degrade during each cycle can vary significantly depending on the operating conditions.
