Soundon battery Advantage :


1.Specilist for lithium battery of Lamination Technology with prismatic case


 Why we choose flexible packaging lamination?


1,slight bending of electrodes can be accepted.

2,the increment of thickness can be accepted.

3, internal defects can be exposed.

4,spherical heat dissipation

5,PP packaging is safer than metal or plastic packaging


2) .Soundon  produce battery cells and battery pack with Lifepo4 , LI polymer with prismatic case are mainly applied in electric Vehicle ,Energy storagae 


Lifepo4 battery and lipolymer battery cells models with below advantage  :


  •  3C high discharge current :
  •  longer cyclelife : lifepo4 :>3000 times  lipolymer >2000times 
  •  unique Lamination technology :
  • power battery cell type for  EV battery pack ,
  • High density cells for Energy storage ,
  • high capacity battery cells from 10Ah ~50Ah ,can flexiable assemble to any battery pack
