Lithium battery charging essence

Can lithium-ion batteries be charged fast?

The possibilities of fast charging of lithium-ion batteries are determined, first of all, by the kinetics of current-producing processes during charging, and, therefore, depend on the nature of the electrochemical system, the structure of the electrodes, and separators.

Why is fast charging a problem in lithium-ion batteries?

Fast charging confronts significant difficulties in the later stages of constant current charging of lithium-ion batteries due to uneven SEI film or unstable structure that increases the risk of lithium evolution and leads to poor battery cycle performance [7, 8, 9].

Which dopants can be used to charge a lithium ion battery?

Other dopants of interest for lithium-ion batteries capable of fast charging include phosphorus [149, 153] and sulfur [153, 154]. The authors of explain the ultra-high capacity and the ability to operate at elevated C-rates by a new nanostructure and a high level of nitrogen doping.

How does a high concentration electrolyte affect the charging performance of lithium-ion batteries?

As a result, a local high concentration electrolyte was selected to change the solvation structure in the electrolyte and achieve the fast-charging performance of lithium-ion batteries [35, 36, 37]. Figure 1. Schematic illustration for charging a Lithium-ion battery.

Can lithium-ion batteries extend the driving range of electric vehicles?

Enhancing the fast-charging capability of lithium-ion batteries is a promising way to extend the driving range of electric vehicles. One of the most effective and economic ways is to regulate the electrode-electrolyte interphase chemistry by employing electrolyte additives.

How to manage lithium-ion battery charging strategies?

To achieve intelligent monitoring and management of lithium-ion battery charging strategies, techniques such as equivalent battery models, cloud-based big data, and machine learning can be leveraged.
