1. 3D thick plates ----- long life,long corrosion life

Dongjin Battery solution

Traditional plate type
Dongjin Battery solution
3D type
*hold more AM       *More contact surface are
*triangle contraction-more stable  *thickness ↑20%+    *cycling ↑20-30%

2. High Sn Low Ca Alloy – High corrosion resistance

Dongjin Battery solution

3. Pancake plates design---increase cycling life 2X

Dongjin Battery solution
Pancake plates
Pancake plates design,eliminate stratification, decrease the uniformity, increase charge acceptance and cycle life.
Dongjin Battery solution
Vertical Plates
Vertical plates , stratification will get worse during operation, it will produce sulphation and leads to uniformity and low charge acceptance.

4. Hybrid Gel electrolyte – get better HT resistance

Dongjin Battery solution
  • Nano Gel electrolyte
  • More electrolyte – less sensitive for "dry out", higher heat dissipate efficiency from container
  • Nano silica particles easy dispersed into the separator – decrease the float current
  • Microcosmic colloidal stable network/structure ,decrease the electrolyte "stratification”
  • Thus increase the cycle life around 30%

5. Hybrid Gel Electrolyte – decrease stratification ,increase charge acceptance

Dongjin Battery solution
  • All LAB has Stra
  • Gel > Hybrid > AGM > Vented
