Patent Application No. K01820

The high-performance lithium-ion battery that uses "lithium iron phosphate" asthe cathode material. No installation work is required, the unit can be moved easily,
and functions can be expanded freely by stacking units. Power can be supplied
to multiple devices through AC/USB ports with power as a powerful generator.

SafetyHas a strong crystal structure and is resistant to sharp nails
and has high thermal stability. Abnormality is automaticallydetected during overcharge and discharge.

LowSelf-discharge

The self-discharge rate of 1% per month enables
long-term storage. * The self-discharge rate oflead secondary battery is 20% per 1 month.

Long LifeHas a discharge depth of 100%, can be used over 2,000
times repeatedly, and has 4 ~ 6 times longer life than othersecondary batteries.

Rapid Charge
and Discharge

1/10 faster charging and discharging than leadacid batteries.

High-power
Discharge

Has an overwhelmingly high output discharge capability
compared with lead secondary batteries. It can also be used
for high-output power systems such as industrial machinery.

Low-temperature
ResistanceHas low-temperature resistant performance
which can be stably utilized even in the severe
environment of minus 20 ° C.
