Li-polymer Battery,with high energy density, miniaturization, ultra-thin, lightweight, and high safety and low cost, and other obvious advantages, is a new type of battery. In shape, lithium polymer batteries are ultra-thin and can be made into batteries of any shape and capacity according to the needs of various products. This type of battery can reach a minimum thickness of 0.5mm.
compared with other battery ,Li-Polymer Battery has some feature as below:
1.Good safety performance :Li-polymer battery with aluminum composite flexible packaging in the structure, different from liquid metal case of batteries, in the event of a safety hazard, liquid batteries can be easily explode, and but li-polymer batteries will only be swollen at most
2.light weight :Batteries that use polymer electrolytes do not need a metal case for protection package. The polymer battery weighs 40% less than the steel Lithium battery of the same capacity specification and 20% less than the aluminum battery
3.small internal impedance:The internal resistance of the polymer batteries is less than liquid batteries, the current domestic internal resistance of the li-polymer batteries can even be produced below 35 m Ω, greatly reduced the battery power Self-consuming, extend the standby time of mobile phone, can meet international level. This kind of li-polymer battery, which supports large discharge current, is the ideal choice for remote control model and becomes the most promising product to replace nickel metal hydride battery.
4,Shape customizable:Manufacturers do not have to be limited to standard shapes and can be economical with the proper size. Polymer battery can increase or decrease the thickness of the batteries according to the customer's demand, even develop new batteries models, the price is cheaper and mouding case time is short, some even can be customized according to the mobile phone shape, to make full use of the battery shell space, improve battery capacity.
5.Good discharge performance :Compared with liquid electrolyte, colloidal electrolyte has stable discharge performance and higher discharge platform
6.easily deisgn the protection circuits for li-polymer battery packs
