We present optical in situ investigations of lithium-ion dynamics lithium iron phosphate based positive electrodes. The change reflectivity these cathodes during charge and discharge is used to estimate apparent diffusion coefficients for the lithiation delithiation process entire electrode. Thereby, a scaling analysis transport applied, which clearly reveals its diffusive character. Results ar...

A series of LiMn1-x-yFexVyPO4 (LMFVP) nanomaterials have been synthesized using a pilot-scale continuous hydrothermal synthesis process (CHFS) and evaluated as high voltage cathodes in Li-ion batteries at a production rate of 0.25 kg h-1. The rapid synthesis and screening approach has allowed the specific capacity of the high Mn content olivines to be optimized, particularly at high discharge r...

Inspired by Taichi, we proposed rigid-flexible coupling concept and herein developed a highly promising solid polymer electrolyte comprised of poly (ethylene oxide), poly (cyano acrylate), lithium bis(oxalate)borate and robust cellulose nonwoven. Our investigation revealed that this new class solid polymer electrolyte possessed comprehensive properties in high mechanical integrity strength, suf...

Summary Advancing lithium-ion battery technology requires the optimization of cycling protocols. A new data-driven methodology is demonstrated for rapid, accurate prediction cycle life obtained by protocols using a single test lasting only 3 cycles, enabling rapid exploration protocol design spaces with orders magnitude reduction in testing time. We achieve this combining lifetime earl...

The prediction of the degradation lithium-ion batteries is essential for various applications and optimized recycling schemes. In order to address this issue, study aims predict cycle lives using only data from early cycles. To reach such an objective, experimental raw 121 commercial lithium iron phosphate/graphite cells are gathered literature. analyzed, suitable input features generated use d...
