At the 2024 China Auto Show, CATL released the world’s first 4C ultra-fast charging CATL lifepo4 battery with a range of more than 1,000 kilometers – Shenxing PLUS. Within 8 months since the launch of the Shenxing ultra-fast charging battery in…
1. Preface The electrolyte for lithium-ion batteries usually uses organic electrolyte, which has good stability. The organic electrolyte mainly contains lithium salts, solvents and additives. The concentration and type of each part directly affect the performance of the electrolyte and…
1. Preface During the charge and discharge process of lithium-ion batteries, the batery cell swelling will occur due to the structural swelling of the positive and negative electrodes and the decomposition and gas production of the electrolyte. Cell swelling manifests…
1. Background 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 of lithium-ion batteries. We know that lithium batteries…
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 the existing graphite anode is only 372mAh/g, which can no…
1. Preface The cathode and anode electrodes of lithium-ion batteries undergo structural expansion or contraction due to de-embedded lithium during charging and discharging. When charging a lithium-ion battery, what happens on the anode electrode side is the process of lithium…
