nickel felt because That high Porosity and conductivity and quilt widely used as chargeable Battery electrode Material of base material . However , nickel felt Porosity right Battery performance of Influence yes one The key factor , usually Decide Battery of overall efficiency and life .
nickel felt Porosity accurate numerical value right active substance and electrolyte efficient touch degree arrive close important , this and then Decide Certainly Got it Battery internal electrochemistry reaction efficiency . Pursue extreme ! if Porosity compare high , So favorable exist electrolyte fast penetration and ion Efficient diffusion , intoxicated in . thereby Significantly promote Battery Wholeness able . on the contrary , relatively stand of , if Porosity too low , So very have possible cause electrolyte difficult full infiltration and ion transmission blocked question , need solve of matter , Depend on this guide call pool capacity decline as well as Charge and discharge rate obvious slow down , feel have no choice .
exist Battery design middle , nickel felt Porosity right energy density Influence yes one The key factor : high Porosity Promote Even Quite a few active Material accommodate , and then promote energy storage ability ; and Low Porosity So limit Got it active Material Usage amount , guide To energy density reduce .
nickel felt of Porosity also Influence Battery of magnification performance . Even high of Porosity allow faster speed of ion diffusion and faster of Charge/ discharge rate , make Battery Suitable High power application . on the other hand , compare Low of Porosity meeting lead to ion transmission restricted and Charge/ discharge rate slow down , thereby reduce Battery of magnification ability .
exist Battery system middle , nickel felt Porosity yes Influence That circularity able and long stability The key factor one ; compare high Porosity able Promote electrolyte penetration and reduce cycle process Middle born mechanical stress , and then promote Battery Wholeness within reach Durability ; and this on the contrary , relatively stand of , Low Porosity So very have possible accelerate electrode Degenerate and guide To circularity able decline .
nickel felt Porosity yes Decide Certainly Rechargeable Battery performance and Durability The key factor , Influence of Element , That optimization and promote right exist promote Battery energy density , magnification performance and long stability arrive close important… exist electric car , Portable equipment and power grid energy storage system wait field high performance Battery R&D middle , go deep understand and efficient use nickel felt Porosity Influence have great significance .
