1. Research Background High-nickel cathode materials are widely recognized as a popular choice of cathode materials for high-energy-density lithium-ion batteries due to their high capacity and low-cost benefits. However, fast charging and long cycling at high voltage can trigger serious…
1. Preface There are three main encapsulation forms for lithium batteries, namely pouch cell, prismatic cell and cylindrical cell. pouch cells use aluminum-plastic film as the encapsulation material, which provides design flexibility and a variety of models, and the shape…
1. Composite Fluid Technology Background Composite current collector is a “sandwich” structure, the inner polymer polymer layer (such as PET, PP or PI), both sides of the metal conductive layer (such as Al or Cu), such as Figure 1 for…
1. Preface In this paper, we explore the correlation between electrolyte wettability and electrode tortuosity by testing the tortuosity and wetting rate of electrodes with different compaction densities to provide some new methods for electrode design and optimization. In the…
On November 2-3, 2024, the 9th National Solid State Battery Symposium was successfully held in Xiamen, hosted by the Solid State Ionics Branch of the Chinese Silicate Society, and co-sponsored by Xiamen University, Fujian Battery Technology Association, and IEST With…
1. Preface Lithium-ion batteries stand out from many other energy storage technologies due to their advantages of high energy density, long cycle life, low self-discharge rate, no memory effect, etc., and have become the most important part of the current…
1. Preface The degree of electrolyte wetting is one of the key factors affecting the performance of lithium-ion batteries such as kinetics, cycle life, and safety and reliability, etc. A good wetting effect can form a uniform interface between the…
1. Preface Powder materials’ resistivity and compaction density are important indicators for material monitoring in the current lithium industry, and their determination is usually done under different quantitative pressures. The process of powder compression is a complex physical phenomenon involving…
CATL, the world’s largest electric vehicle battery maker, launched the Freevoy Super Hybrid Battery on October 24th, the world’s first hybrid battery with an all-electric range of more than 400 kilometers (250 miles) and 4C ultra-fast charging. The new battery…
The Zaragoza plant of globally recognized automotive manufacturing giant Stellantis is partnering with CATL, the world’s largest manufacturer of electric vehicle batteries, to expand its automotive battery plant and electric vehicle production platform in Zaragoza. On October 8, Spain’s Industry…
