The polymer lithium battery is one of a lithium ion battery, but has a variety of energy densities, minimalized, ultra-thin, lightweight, and high safety and low cost than liquid lithium batteries (Li-ION). Obvious advantage is a new battery. Here we detail the advantages and disadvantages of polymer lithium batteries.Lithium polymer battery
First, the advantages:
1. Good safety performance
The polymer lithium battery is in structure, aluminum-plastic soft packaging, is different from the metal casing of the liquid electrical cell, and once the safety hazard occurs, the liquid electrical cell is easily exploded, and the polymer battery is only a drum.
2. Small thickness, you can do more
Ultra-thin, the battery can be assembled into the credit card. Ordinary liquid lithium electricity uses advanced shells, after the positive and negative village, the thickness is 3.6mm or less, the polymer battery does not exist, the thickness can be 1mm or less, in line with the time of mobile phone demand direction.
3. Light weight
Battery using a polymer electrolyte does not require a metal shell as a protective outer packaging. The weight of the polymer battery is less than 40% of the steel shell of the same capacity specification, 20% lighter than the aluminum shell battery.
4. Capacity
Polymer battery is more than 10 to 15% higher than the same size specification, 5 to 10% higher than the aluminum shell battery, becoming the preferred choice for color screen mobile phones and MMS mobile phones. Nowadays, new color screens and MMS mobile phones are mostly used. Polymer batteries.
5. Internal resistance
The internal resistance of the polymer battery is less than the general liquid cell. At present, the internal resistance of the domestic polymer battery can even achieve less than 35MΩ, which greatly reduces the self-consuming power of the battery, and extend the standby time of the phone, it can be achieved. Level with internationally launched. This polymer lithium-supported polymer that supports large discharge current is ideal for the remote control model, which is the most promising product of the NiMH battery.
6. Customizable shape
The manufacturer does not have to be limited to standard profiles, which can be economically made in a suitable size. The polymer battery can increase or reduce the thickness of the customer, develop the new battery core model, the price is cheap, the opening die period is short, and some can even do it according to the amount of mobile phone shape to make full use of battery housing space, and improve the battery. capacity.
7. Good discharge characteristics
The polymer battery has a colloidal electrolyte, compared to the liquid electrolyte, the colloidal electrolyte has a smooth discharge characteristic and a higher discharge platform.
8. Simple protection board design
Due to the use of polymeric materials, the cell does not afford fire, not exploded, the battery cell itself has sufficient safety, so the protective line design of the polymer battery can consider omitting the PTC and fuses, thereby saving battery costs.
Second, the shortcomings:
And the amount of energy density and cycle is lowered compared to the lithium ion battery.
Manufacture is expensive.
There is no standard shape, most batteries are manufactured for high-capacity consumer markets.
