It means that MFR membrane holds Mn 2+ ions in the separator instead of allowing them pass through. In LiMn2 O 4 /graphite batteries, the MFR membrane can cheat with the dissolved Mn 2+ ions and suppress their deposition on the graphite anode, mitigating the ohmic polarization and improving the cycle performance. Fig. 8.
In this work, a multifunctional thermoset nonwoven membrane composed of melamine formaldehyde resin (MFR) nano-fibers was prepared by a electro-spinning method. The resultant porous nonwoven membrane possesses superior permeability, electrolyte wettability and thermally dimensional stability.
The catalytic material for lithium–sulfur batteries has a specific capacity of 605 mAh/g after 1000 cycles at 2 C, a capacity decay rate of 0.045%/cycle, and excellent cycling stability.
Melamine formaldehyde resin (MF) containing large amounts of nitrogen (N) and amino groups, which can be used as carbon source and nitrogen source to the electrode material, and obtain superior electrochemical performance. However, the carbon residue rate of MF carbonization is low and the pore structure is underdeveloped.
Zhang et al. [ 79] used PVP as dispersant and nucleating agent to produce HMM-PVP from melamine and formaldehyde, then Co 2+ was complexed with resin and carbonized with selenium to prepare N rich layered porous carbon (CS/NPC) coated Co 0.85 Se nanoparticles for lithium-ion batteries.
