TL;DR: In this paper, the dissolution of spinel manganese oxides and the concomitant cathodic capacity losses were examined in 4 V Li/PC + DME + LiClO 4 /Li x Mn 2 O 4 cells where PC is propylene carbonate and DME is dimethoxyethane.

TL;DR: The amorphous red phosphorus/carbon composite shows excellent electrochemical performance including a high specific capacity, negligible capacity fading over 30 cycles, an ideal redox potential, and an excellent rate performance, thus making it a promising candidate for Na ion batteries.

TL;DR: In this paper, a mesoporous carbon with regular three-dimensionalally interconnected 2 nm pore arrays using AlMCM-48 as a template has been synthesized, which exhibited excellent performance as an electrochemical double layer capacitor.

TL;DR: It is likely that, when tested as the anode in Li secondary batteries, the spherical hollow carbon acts as a barrier to prevent the aggregation of nanosized Sn particles and provides a void space for Sn metal particles to experience a volume change without a collapse of carbon shell, giving rise to a better cycle performance than that of pure Sn metal.

TL;DR: Si composite negative electrodes for lithium secondary batteries degrade in the dealloying period with an abrupt increase in internal resistance that is caused by a breakdown of conductive network made between Si and carbon particles as discussed by the authors.
