Are integrated battery systems a promising future for high-energy lithium-ion batteries?

On account of major bottlenecks of the power lithium-ion battery, authors come up with the concept of integrated battery systems, which will be a promising future for high-energy lithium-ion batteries to improve energy density and alleviate anxiety of electric vehicles.

Are lithium-ion batteries a good energy storage system?

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.

Are lithium-ion batteries a bottleneck?

In recent years, researchers have worked hard to improve the energy density, safety, environmental impact, and service life of lithium-ion batteries. The energy density of the traditional lithium-ion battery technology is now close to the bottleneck, and there is limited room for further optimization.

What is a lithium ion battery?

Unlike Li-S batteries and Li-O 2 batteries, currently commercialized lithium-ion batteries have been applied in the production of practical electric vehicles, simultaneously meeting comprehensive electrochemical performances in energy density, lifetime, safety, power density, rate properties, and cost requirements.

Which lithium ion battery has the highest energy density?

At present, the publicly reported highest energy density of lithium-ion batteries (lithium-ion batteries in the traditional sense) based on embedded reactive positive materials is the anode-free soft-pack battery developed by Professor Jeff Dahn's research team (575 Wh kg −1, 1414 Wh L −1) .

Are rechargeable lithium batteries a good investment?

There is great interest in exploring advanced rechargeable lithium batteries with desirable energy and power capabilities for applications in portable electronics, smart grids, and electric vehicles. In practice, high-capacity and low-cost electrode materials play an important role in sustaining the progresses in lithium-ion batteries.
