Zhang Xiaofei Lithium Battery Energy Storage

Is fast energy storage a problem for lithium ion batteries?

Fast energy storage performance is strongly considered as one of the core techniques for next-generation battery techniques. However, the lack of high-performance electrode materials, especially high-rate and safe anode materials, is still a great challenge for lithium ion batteries and other battery systems.

Are lithium-sulfur batteries a good choice for energy storage?

Lithium–sulfur (Li–S) batteries are promising candidates for energy storage, but suffer from capacity and cycling challenges caused by the serious shuttling effect of polysulfide (PS) ions. To address these issues, a sodium alginate (SA)‐derived affinity laminated chromatography membrane built‐in electrode is designed.

Why are organic electrode materials important in lithium-ion batteries?

Organic electrode materials play a crucial role in environmentally friendly and sustainable lithium-ion batteries (LIBs) due to their abundance, high theoretical capacity, inexpensiveness, and recyclability. However, critical issues such as fewer redox-active sites and poor structural stability limit their extensive application in LIBs.

Can graphite increase energy density of lithium ion batteries?

The low specific capacity of graphite limits the further increase of energy density of lithium ion batteries and their widespread applications. Exploring new anode materials is the key issue. Herein, a new Mullite-type compound Bi2Mn4O10 is designed and synthesized.

Is Li3V2 a suitable cathode material for Next-Generation Li ion batteries?

Li3V2 (PO4)3 (abbreviated as LVP) is considered as a prospective cathode material for next-generation Li ion batteries due to its high specific capacity and high operating potential. However, its low electronic conductivity and the difficulty in morphology control restrict its widespread application.

Is silica based anode suitable for high energy density Li-ion batteries?

Silica-based anode is widely employed for high energy density Li-ion batteries owing to their high theoretical specific capacity (4200 mA h g⁻¹). However, it is always accompanied by a huge volume expansion (300%) and shrinks during the lithiation/delithiation process, further leading to low cycle stability.
