 At all times, the lithium outperforms the AGM at a lower amortized
cost.
 In any application that will fully utilize the capacity of the batteries,
lithium is more cost effective.

 Continuous Automated Cell Assembly Processes
 Improved Safety
 High Discharge Rate Capability (20C-rate continuous)
 Faster Recharge Rate
 Various Capacity Prismatic (6mAh to 240Ah cell in production)
 Automation for better quality and cost control
S L P B TYPE
Principle of SLPB (WORLDWIDE PATENT)

SLPB technology contains no metal lithium.

Only Li-ion passes between the positive and negative poles leaving the
cathode and anode materials unchanged.

The principle operation is fundamentally different and safer than that of
a rechargeable lithium metal battery.

The patented folder to folder design reduces IR significantly
