Abstract:

The demand for Lithium-ion batteries (LIBs) has been growing exponentially in recent years due to the proliferation of electric vehicles (EV). A large amount of lithium-ion batteries are expected to reach their end-of-life (EOL) within five to seven years. The improper disposal of EOL lithium-ion batteries generates enormous amounts of flammable and explosive hazardous waste. Therefore, cost-effectively recycling LIBs becomes urgent needs. Lithium nickel cobalt manganese oxides (NCM) are one of the most essential cathode materials for EV applications due to their long cycle life, high capacity

The more popular active material for negative electrode is usually flake graphite due to its excellent cycle life (up to 1000 cycles).

Si, Sn, Al, hard carbons and some other materials are actively investigated as the alternate materials for lithium-ion batteries. However, they have not received a practical application, since their large theoretical capacity is accompanied by sharp drop of capacity (during the few cycles), high irreversible capacity (up to 50

Abstract:

Carbon nitrides are a unique family of nitrogen-rich carbon materials with multiple beneficial properties for effective alkali metal ion transport/storage. Graphitic carbon nitride (g-C3N4) is considered the most viable member of the carbon nitride family because of its high nitrogen content, wide structure with several nitrogen-defect pore sites, ease of synthesis, affordability, and scalability. Also, g-C3N4 delivers a lithium ion battery (LIBs) theoretical capacity of 524 mAh/g unlike graphite which records only 327 mAh/g. However, due to the ineffective intercalation/deintercalation reacti

Abstract:

Dans ce travail, des matériaux hybrides polymères-silice poreuse sous forme de poudre et de film mince ont été synthétisés et caractérisés. L'étude préliminaire de leurs conductivité ionique Li+ a également été réalisée. Les poudres hybrides ont été synthétisées par voie sol-gel en utilisant des triblocs classiques (Pluronic, P123) et des diblocs copolymères amphiphiles bifonctinels fabriqués en laboratoire comme agents dirigeant la structure (SDA). Dans le premier cas, la modification post-synthétique a été utilisée pour fonctionnaliser la surface des pores de la silice avec du PEO. Dans un s
