As we all know, lithium-ion batteries will experience structural swelling and contraction during de-lithium extraction For negative electrode materials, whether it is intercalated lithium intercalation of graphite or alloyed lithium…

Silicon negative electrode material, with its unique advantages of high theoretical capacity (4200mAh/g) and abundant resources, is expected to replace widely used graphite negative electrodes and become the main negative…

Lithium-ion batteries have been widely used in all aspects of life, such as mobile phones, cars or household energy storage, etc. Therefore, it is particularly important to evaluate various performances…

With the vigorous development of the new energy industry, lithium-ion batteries are gradually developing in the direction of higher energy density and longer cycle life. The theoretical gram capacity of…

Market Status With the vigorous development of the new energy industry, lithium-ion batteries are gradually developing in the direction of higher energy density and longer cycle life. The theoretical gram…

Lithium battery  expansion or contraction due to the deintercalation of lithium during the charge and discharge process. When charging a lithium-ion battery, what happens on the negative electrode side is…

Article Abstract Structural instability and stress accumulation-induced cyclic degradation of silicon (Si) anodes hinder their practical application in next-generation high-energy-density lithium-ion batteries (LIBs). Recently, Master Chen Jiahao and Professor Yang…

Cathode, anode, electrolyte and separator are the four main materials that make up lithium-ion batteries. During the charging process of a lithium-ion battery, lithium ions are detached from the cathode…
