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.

Q2. How to store Li-Po batteries if I will not use them for a while?

1. The cells shall be stored in an environment with low humidity free from corrosive gas and combustible material within a temperature range of -10 to 40℃.

2. It is recommended to strictly obey the first-in first-out (FIFO) principle through manufacturing and distribution of the product.

3. A higher cell voltage during storage will accelerate the deterioration of capacity, it is recommended to keep the cells at a lower voltage (about 3.8V/cell) throughout the period of storage. Storage for a long period may result in over-discharge, due to
self-discharge of the cells. When you need to store batteries for more than one year, charge the cells at least once a year to about 3.8V/cell so as to prevent over-discharge.

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.

Organic solvents easily decompose on the negative electrodes during charging, leading to battery swelling, drop of cell capacity, and unsafety caused by activereaction. The purpose of the formation process is to form a solid layer called the solid electrolyte interphase (SEl), which is electrically insulating yet provides significant ionic conductivity. This interphase prevents further decomposition of the electrolyte after the second charging.
