High-capacity anode materials (e.g., Si) are highly needed for high energy density battery systems, but they usually suffer from low initial coulombic efficiency (CE), short cycle life, and low-rate capability caused by large volume changes during the charge discharge process. Here, a novel dendrimer-based binder boosting electrochemical performance of Si anodes is developed. The polyamidoamine (PMM) dendrimer not only can be used as binder, also utilized crosslinker to construct 3D...
Microsized silicon (μSi) anodes take advantage of low-cost, high tap density, and theoretical capacity (∼4200 mAh g–1). However, poor cycle stability is presented because huge volume change during cycling, which seriously limits their practical application in commercial lithium-ion batteries. Herein, a tough composite network combining electronic ionic conductivity developed to stabilize the operation μSi anode. The resultant electrode exhibits 3789.0 g–1 with initial Coulombic efficiency...
The introduction of 'defects' to the thermoset crosslinking network is one most applicable strategies for improving modulus and toughness simultaneously. However, reinforcement effect disappears when proportion exceeds threshold. speculated mechanism was that aggregation entanglement chains changed matrix topology, making stacking structure more compact. are hardly directly observed in experiment. As result, relationship between package state matrix, on material's mechanical performance not...
