Polymer lithium-ion batteries adopt
s t acked s t ruc ture and ge l po lymer
electrolytes, which are in favor of the
development of thin batteries with design
f lexibi l i ty. The use of gel polymer
electrolytes enables fabrication of safe
batteries, which won’t explode or catch fire
in extreme circumstances, such as crush,
penetration or short-circuit etc.. So

Charge and Discharge Mechanism of Charge and Discharge Mechanism of Charge and Discharge Mechanism of Polymer LithiumPolymer LithiumPolymer Lithium---ion Batteryion Batteryion Battery
In polymer lithium-ion batteries,
liquid electrolytes are replaced by gel
polymer electrolytes. The gel polymer
electrolytes not only have good ionic
conductivity, but also can act as
separator in polymer battery. The
electrodes of polymer lithium-ion
battery are basically the same as
liquid lithium-ion battery, so the
working principles of them are similar.
Figure1 is the charging and discharging principle of polymer lithium-ion battery. During
the process of charge and discharge, lithium ions intercalate into and de-intercalate from the
electrodes through the gel polymer electrolytes. And then the battery converts chemical
e n e r g y i n t o e l e c t r i c e n e r g y .
Positive MaterialsPositive MaterialsPositive Materials
Spinel lithium manganese oxide has been investigated extensively as a
promising positive material for polymer lithium-ion battery because of the
following advantages: (1) abundance and low cost; (2) environment
protection; (3) good safety and overcharge resistance. The cycle performance
at room temperature and elevated temperature has been improved
e x t e n s i v e l y b y m o d i f y i n g t h e sp ine l L i -Mn-O compound .
Negative MaterialsNegative MaterialsNegative Materials
Negative materials have special advantages in structure and morphology: (1) spherical structure with high pile-density is available for compact filling and the improvement of energy density. (2) small specific surface area improves safety and reduces the irreversible capacity loss resulted from the formation of SEI layer during the initial charge/discharge cycle. (3) layered graphitic structure is in favor of reversible intercalation/deintercalation of lithium ions. (4) special sphere and stable inner structure permit high rate charge and discharge.

The gel polymer electrolytes not only have good ionic conductivity, but also can
act as separator in polymer battery. The liquid electrolyte and lithium salt are
absorbed sufficiently, which can ensure the inner gel system and safety of battery.
