Lithium-ion Battery and Energy Products
Lithium-ion Battery
Overview
Lithium-ion battery as a kind of clean energy is getting more and more attentions according to the worldwide energy shortage. BYD lithium-ion batteries includes lithium-ion cell, lithium-ion battery pack, li-polymer battery, etc., which are widely used in many applications. Many domestic and international companies, like , Samsung, LG, Huawei, Lenovo, ZTE, TCL, etc., are among the clients of BYD Li-battery Co, Ltd .

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

1. 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.

2. 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.

3. Long cycle life
The Cycle Life of lithium-ion battery is over 500 in normal condition.

4. 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.
