Li-ion Polymer Batteries

Historically, lead-acid, nickel-cadmium (Ni-Cd), and nickel-metal hydride (Ni-MH) batteries have been the conventional choice for small-sized rechargeable batteries. In line with the recent trends toward mobile and cordless electronic equipment, rechargeable batteries are required to provide higher energy density to meet the needs of ever smaller and lighter devices. Moreover, the attention being focused on protecting the environment has resulted in demand for products that are environmentally friendly.

Features 

• High Energy Density
• The weight of a lithium ion battery is approximately one half compared to a nickel-cadmium or nickel-metal hydride battery of similar capacity. Moreover, the volume of the lithium ion battery is 40 to 50% smaller than that of a nickel-cadmium and 20 to 30% smaller than that of a nickel-metal hydride battery. 
• High Voltage
  A single lithium ion cell has a voltage of 3.7V (mean value), which is equal to either three nickel-cadmium or nickel-metal hydride cells connected in series.
• Good safety performance 
  As the aluminum bluster outer package is different from the meta shell of liquid lithium ion battery, and once safety problems arise, there is no explosion but only expansion. 
• Pollution-free
  The lithium ion battery does not contain any polluting substances such as cadmium, lead, mercury, etc.
• Various capacities and sizes
  various capacities and sizes and can be customized for capacity of 40mAh～20Ah and thickness of 0.8mm～10mm.
• Long Cycle Life
  Under normal conditions, the lithium ion battery has a life of more than 500 charge/discharge cycles.
• No Memory Effect
  The lithium ion battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.
• Fast Charge Capacity
  The lithium ion battery can be fully charged in 1 to 2 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charger with a rated voltage of 4.2V per cell.

 

 Applications

The rechargeable lithium ion battery shows great promise as a battery to meet such requirement. This new battery technology has excellent features, such as: high energy density, high voltage, good storage and cycle life characteristics. These batteries are widely used for 3C applications such as: Personal Computers, Cellular Phones, and for personal cordless electronic applications i.e. Portable CD Players, PDA etc.
