High power using lithium battery

How to improve the energy density of lithium batteries?

Strategies such as improving the active material of the cathode, improving the specific capacity of the cathode/anode material, developing lithium metal anode/anode-free lithium batteries, using solid-state electrolytes and developing new energy storage systems have been used in the research of improving the energy density of lithium batteries.

How can a lithium ion battery have a high power density?

To obtain lithium-ion batteries with a high power density, the cathode materials should possess high voltage and high electronic/ionic conductivity, which can be realized by selecting high-voltage materials and modifying them to improve the voltage and reduce the battery’s internal resistance.

Which cathode material can raise the energy density of lithium-ion battery?

Among the above cathode materials, the sulfur-based cathode material can raise the energy density of lithium-ion battery to a new level, which is the most promising cathode material for the development of high-energy density lithium batteries in addition to high-voltage lithium cobaltate and high‑nickel cathode materials. 7.2. Lithium-air battery

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.

What are the applications of lithium-ion batteries?

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 [, , ].

Are rechargeable lithium batteries a good investment?
