BATTERY GRADE

①I(mǎi)ntroduction:CMC is an important component of lithium battery. It is acted as thickener make the toner distributed evently on the copper foil together with the bond- SBR.

②Character:

1.Bind the active substance, conductive agent and current collector together;

2.Fix firmly electrode material on the current collector;

3.Excellent conductivity reduces the impedance between electrode material and current collector;

4.Good heat stability enhances the battery circulation stability and lifespan circulation;

5.Good electrochemistry stability, and stable with the electrode material and electrolyte;

6.Release the expansion and shrink during the li-battery in charging or discharging;

7.Less usage, strength bind, low load discharging;

8.Safety,environment-friendly and cost-saving.
