After looking at the Challenges of Adding Silicon to Graphite Anodes it is important we look at options that solve the expansion of silicon anodes. To solve the severe volumetric expansion of silicon anodes—which can swell by 300% to 400% during charging—researchers and manufacturers rely on a combination of material engineering, chemical stabilization, and electrode … Read more

Author: Dr. Hitoshi Nakamura Lithium-ion battery degradation usually starts at the anode. Sanyo was the first to use Carboxymethyl Cellulose (CMC) in anode slurry. At first, the life of the battery was short, and this was due to lumps. When there are lumps, the area is electrically insulated, so it is easy for SEI to … Read more
Graphite remains the most widely used anode material in lithium-ion batteries, and the initial formation of the solid electrolyte interphase (or SEI) largely dictates the long-term performance of commercial cells. In this post we take a look at the work of WMG, University of Warwick and James Durrans & Sons Limited. A preprint copy of … Read more
AION Engineering INC In lithium-ion battery technology, optimizing cell performance and safety requires careful consideration of multiple parameters. Among these, the cut-off voltage is critical for balancing energy density and ensuring cell longevity and stability. While cathode chemistry often guides cell classification, variations in anode materials significantly impact the appropriate cut-off voltage setting. Influence of … Read more
Isotropic graphite is designed to reduce the stress from Li+ insertion and extraction [1]. Making it more stable and thus improving lifetime. By introducing isotropic technology, lithium ions can be inserted into the graphite channel from any angle, which in turn greatly increases the charging speed. CATL [2] Wu et al [1] describe the process … Read more
