Sionic Energy and Group14 set new high-temperature benchmark for silicon-carbon anodes
Battery technology company Sionic Energy, together with Group14 Technologies, has announced the results of testing that demonstrates a new level of high-temperature stability for 100% silicon-carbon anodes in lithium-ion cells. By combining Group14’s SCC55 silicon-carbon anode material with Sionic’s proprietary Rapid Integration Silicon Platform containing 100% silicon-carbon (Si-C) anode and enhanced electrolyte, the companies “have… Read more »
Operando X-ray tomography reveals silicon-electrolyte interface dynamics in solid-state batteries
Silicon anodes can greatly boost the energy density of all-solid-state batteries, but their large volume changes often cause contact loss with solid electrolytes. Si can store more lithium than graphite, but its volume can expand by as much as 410% during charging, generating mechanical stress that cracks particles and weakens their contact with the solid… Read more »
PEM tests feasibility of battery cells containing 80% recycled content
The Chair of Production Engineering of E-Mobility Components (PEM) at RWTH Aachen University is working with industrial partners on the Kreislauf.IN.NRW battery cell recycling research project. The project, funded by the Ministry for the Environment, Nature Conservation and Transport of the State of North Rhine-Westphalia, aims to investigate the production and functionality of cells containing… Read more »
Sakuu reports breakthrough in dry-processed battery cell, retaining 83% charge after 4000 cycles
Sakuu has announced that its Kavian additive manufacturing platform can dry-print lithium-ion battery cathodes with leading cycle life using existing high-nickel chemistry. The company claims that cells manufactured via Kavian’s fully dry process retained 83 percent of their original charge capacity after 4,000 cycles, surpassing typical standards for EV batteries. According to Sakuu, the tested… Read more »
