polymer (Li-Po) batteries.
In general, the diferences lie in the materials made of the positive & negative terminals, the area density design, the electrolyte ingredient, the septum data and the density of inside pieces.

When a Li-Po battery is made, five main aspects should be considered carefully:

(1). Battery Pack should have suficient strength, so that the polymer battery inside could be efectively protected from mechanical shocks;

(2). The polymer cell should be fixedto the battery pack onits large surface area - no cell movement in the battery packshould be allowed;

(3). No sharp edge components should be inside the packcontaining the polymer battery, and meanwhile, suficient insulation layer between wiring and the cell should be used to maintain multiple safety protection;

(4). Ultrasonic welding is recommended for polymer tab connection to obtain low-resistance, high-reliability and light-weight properties;(5). Polymer packs shouldbe designed carefully so that no shear force is applied, and also, no heat is generated even when leakage ocurs for mishaps. PCM from electrolyte leakage should be isolated as perfectly as posible, and narrow distance between bare circuit patterns should be avoided.

The generated gases include Co, CO2,H2, CH4 and so on. They are not dangerous because of low volume.

How to Charge li-Po battery?

1. Charging Current: Charging current should be less than the maximum charging current listed in specifications. Charging with higher current than recommended may cause serious damage to cell performance and safety features,leading to heat generation or leakage.

2. Charging Voltage: Charging should be performed at a voltage less thanthat listed in specifications (4.20V/cell). Charging at above 4.25V-the absolute maximum voltage, must be strictly prohibited.The chargers used should have this voltage limitation function. Charging with higher voltage than specified is very dangerous, which may cause serious damage to the cell performance and safety features, leading
to heat generation or leakage.

3. Charging Temperature: The cells should be charged within a range of temperatures listed in the specifications. Always let the batteries cool down to ambient temperature before charging.

4. Prohibition of Reverse Charging: Do not reverse the positive(+) and negative(-) terminals. Otherwise, the batery pack wil be reverse-charged and abnormal chemical reactions may ocur. Ecesively high current may flow during recharging, possibly leading to damage, overheating, smoke emission, bursting and/or ignition.

5. Use specific Li-Po charger only. DO NOT use a Ni-MH or Ni-Cd charger. It is your responsibility solely to ensure that the charger you purchased works properly.

6. Never charge batteries unattended. Always monitor charging process to assure batteries are being charged properly. Always charge the batteries in an isolated and safe area away from any flammable or/and combustible materials.
