What are the advantages of polymer batteries?
1.Good safety performance
The polymer lithium battery is made of aluminum-plastic flexible
packaging, which is different from the metal casing of the liquid
battery.Once the safety hazard occurs, the liquid battery is easy
to explode, and the polymer battery can only be air-blasted at
most.
2.Small thickness, can be made thinner
Ultra-thin, the battery can be assembled into a credit
card.Ordinary liquid lithium battery adopts the method of
customizing the outer casing first, and then plugging the positive
and negative materials.The thickness is 3.6mm or less, there is a
technical bottleneck.The polymer battery core does not have this
problem, and the thickness can be less than 1mm, which meets the
needs of current mobile phones.Direction.
3.Light weight
A battery using a polymer electrolyte does not require a metal
shell as a protective outer package.The weight of the polymer
battery is 40% lighter than the steel shell lithium battery of the
same capacity specification, which is 20% lighter than the aluminum
shell battery.
4.Large capacity
The polymer battery has a capacity of 10-15% higher than that of
the same size steel shell battery, which is 5-10% higher than that
of the aluminum shell battery.It is the first choice for color
screen mobile phones and MMS mobile phones.Nowadays, the new color
screen and MMS mobile phones on the market are mostly used.Polymer
batteries.
5.Small internal resistance
The internal resistance of the polymer battery core is smaller than
that of the general liquid battery.At present, the internal
resistance of the domestic polymer battery core can even be less
than 35MΩ, which greatly reduces the self-consumption of the
battery and prolongs the standby time of the mobile phone.The level
of integration with the international.This polymer lithium battery
that supports large discharge currents is an ideal choice for
remote control models and is the most promising alternative to
nickel-metal hydride batteries.
6.Shape can be customized
Manufacturers are not limited to standard shapes and can be
economically made to the right size.Polymer batteries can increase
or decrease the thickness of batteries according to customers'
needs.Develop new battery models, which are cheap, open cycle is
short, and some can even be customized according to the shape of
mobile phones to make full use of battery casing space and upgrade
batteries.Capacity.
7.The protection board is simple in design
Due to the use of polymer materials, the battery core does not
explode, and the battery core itself has sufficient
safety.Therefore, the protective circuit design of the polymer
battery can be omitted by omitting the PTC and the fuse, thereby
saving battery cost.
