1. Preface In this paper, IEST has tested the expansion behavior of sulfide solid-state battery during charging and discharging by using a Solid Electrolyte Test System(SEMS) and a In-Situ Silicon-Based Anode Swelling Rapid Screening System(RSS). Currently the performance of liquid batteries…
The joint venture will build a new lithium iron phosphate (LFP) battery plant at Stellantis’ facility in Zaragoza, Spain. Production is planned to start at the end of 2026, with a potential capacity of 50 GWh Stellantis is committed to…
1. Lithium Plating Phenomenon Lithium plating is a common anomaly in lithium-ion batteries during the use of lithium-ion batteries. The direct cause of lithium plating phenomenon is that the anode material can not provide timely accommodation for free lithium ion…
1. Research Background The current lithium-ion batteries have increasing range requirements, and it is crucial to develop anode materials with high specific capacity and high cycle stability. Silicon is the anode material with the highest theoretical specific capacity (4200 mAh/g),…
Australian battery technology company Li-S Energy has announced significant advances in lithium-sulfur Batteries technology, with energy densities approaching 500 Wh Li-S Energy, headquartered in Queensland, Australia, says its latest full-size 10 Ah semi-solid-state battery achieves an impressive energy density of…
1. Preface With the increasing demand for lithium-ion battery end-products, lithium-ion battery performance also needs to be constantly improved, such as the structural stability of lithium-ion batteries, safety performance and appearance of the hardness and so on. Improving the cell…
1. Research Background In lithium-ion batteries, the anode material, as the main part of lithium ion diffusion and electron transport, determines the performance of the battery to a large extent. The ion diffusion characteristics of cathode have been a hot…
1. Preface The raw materials of lithium-ion batteries mainly include positive electrode materials, negative electrode materials, current collectors, electrolytes and separators. Cathode and anode electrode materials are usually micron-sized powder materials. Among them, common cathode electrode powder materials of lithium-ion…
1. Preface In this paper, we adopt the in-situ swelling analysis system(SWE Series) of IEST to monitor the pressure and thickness deformation of the battery by correlating the SOC and SOH parameters of a single battery, and evaluate the compression…
1. Preface Lithium-ion battery industry is one of the important directions affecting the development of the national economy at present, in the design and research process of lithium-ion battery, materials compaction density is one of the key indicators affecting the…
