The development of portable electronic devices, electric vehicles, and renewable energy systems urgently requires the support of high-performance and high-safety electrochemical energy storage devices, but the current commercial lithium-ion batteries based on traditional organic electrolytes are approaching the performance bottleneck and are toxic. , Volatile and flammable ester electrolytes have great potential safety hazards. Solid-state […]

People are unconscious that overcharge a deep cycle battery is not beneficial for its using cycle life.

1.Why are lithium-ion batteries so powerful? The performance and reliability of lithium-ion batteries depend to a large extent on the electrolyte. The most commonly used electrolytes today are composed of cyclic and linear carbonates containing soluble lithium salts, typically lithium hexafluorophosphate, which have low viscosity and good ionic conductivity. However, the electrolyte is unstable at

The latest achievements of lithium battery technology are as follows. 1. Ultra-low concentration electrolyte realizes highly stable lithium metal battery! The interfacial structure of electrodes is closely related to the electrochemical performance of lithium metal batteries (LMBs). In particular, a high-quality solid-electrode interface (SEI) and a uniform and dense Li deposition/stripping process are crucial to

“Lithium battery” is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Lithium batteries can be roughly divided into
