Applications
|
Lithium-ion
batteries are widely used in the area of mobile phone,
cordless phone, laptop, backup power source, UPS, power
tools, digital products, etc. Li-polymer batteries could be
used in even more applications because of the changeable
shape, such as bluetooth, toys, aeromodelling, GPS, etc.

High Energy Density
The energy density of lithium-ion batteries varies from
chemistry to chemistry. The specific energy density can
range from 100 wh/kg to 125 wh/kg, and volumetric energy
density from 240 wh/L to 300 wh/L (double of the Ni/Cd, 1.5
times of Ni/MH) , which has not reached the maximum energy
density in theory of 150 wh/kg or 400 wh/L.
High Voltage
The operating voltage of one Lithium-ion battery is
3.7V(average value),equivalent to 3 series nickel-cadmium
battery or nickel hydrogen battery.
Long cycle life
The Cycle Life of lithium-ion battery is over 500 in normal
condition.
Environmental Friendly
Lithium-ion batteries contain no polluting metals, such as
cadmium, lead, mercury, etc., or the contents of the
polluting metals are within the international standards.
