| Li-Polymere
batteries have a set of features which makes them very suitable
for a very wide range of portable equipment of any kind.
- high energy
density, especially respective to weight, reaching 140-180Wh/kg,
even higher than Li-Ion
- high cell
voltage of 3.7V, which is equal to 3 NiCd/NiMH cells
- no memory
effect
- fast chargeable
at up to 1C resulting in 2h charge, whereas 80% of the capacity
will be charged during the first hour
- high discharge
currents of up to 2C
- pollution
free, no use of heavy metals like lead, cadmium or mercury
- Lithium is
not used in metal form and therefore does not have any restrictions
for air transportation
- low self
discharge
- life time
of around 500 charge/discharge cycles
- various geometrical
shapes possible, custom design easy to realize
