Literature Appreciation: Entropy Surface Engineering Promotes The Stability Of Multi-electron Reactions Of Anions And Cations In Li-rich Layered Cathodes First Author: Jiayu Zhao Corresponding Authors: Yuefeng Su, Jinyang Dong, Lai Chen Affiliations: Beijing Institute of Technology, Chongqing Innovation Center of…
Perhaps you’re not a professional in the field of electrochemistry, but while browsing relevant journals, attending academic conferences, or visiting websites of electrochemical equipment manufacturers, you may often come across a particular graphic. It presents itself as two peaks resembling…
1. Background As lithium batteries are gradually being applied in various aspects of life, the demands placed on them by people are increasing, such as longer lithium ion battery lifespan and higher energy density. To meet these demands, on the…
Have you heard of the three electrode system? It might be completely different from the batteries we use in our daily lives, which typically have two electrodes: a positive and a negative one. So, why is there a three electrode…
1. Background As we all know, lithium-ion batteries will experience structural swelling and contraction during de-lithium extraction For anode electrode materials, whether it is intercalated lithium intercalation of graphite or alloyed lithium intercalation of silicon-based anode electrodes, the common feature…
1. Preface Silicon anode materials, 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 electrode material for the next generation of lithium-ion batteries.…
1. Author Information and Article Summary In 2022, Dr. Peipei Xu of Beijing University of Science and Technology developed a method to estimate the LiFePO4 SOC based on the expansion force curve of the LiFePO4 batteries. Through experimental verification, it…
1. Author Information and Article Abstract In 2017, the J.R.Dahn research group used the in-situ characterization method to test the volume, stress and thickness changes of the electrodes for pouch cells with different silicon-composite negative electrodes, combined with the calculation…
1. Background This paper uses the cell pressure distribution system (BPD1000) to monitor the pressure distribution of different positions of the cell, so as to quickly quantify and evaluate the flatness of different cell sizes. In the existing process, the…
1. Author information and article abstract 2022, Yonghong Deng’s group at SUSTech, in collaboration with Prof. Zijian Zheng’s team at the Hong Kong Polytechnic University (first author: Chao Luo, a PhD student at SUSTech), developed a roll-to-roll approach to prepare…
