Lithium ion Battery technology introduction

2012/8/16      view:
  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.

  Main Features

 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.
