1. The raw materials for lithium-ion batteries are different, and the raw
materials are electrolyte (liquid or colloid); The raw materials for polymer
lithium batteries are electrolytes, including polymer electrolytes (solid or
colloidal) and organic electrolytes.
2. In terms of safety, lithium-ion batteries simply explode in
high-temperature and high-pressure environments; Polymer lithium batteries use
aluminum plastic film as the outer shell, and when organic electrolytes are used
internally, even if the liquid is very hot, it will not burst.
3. Polymer batteries can achieve thinness, arbitrary surface area, and
arbitrary shape due to the fact that their electrolytes can be solid or
colloidal rather than liquid, while lithium batteries use electrolytes and
require a sturdy outer shell as a secondary packaging to contain the
electrolyte.
4. The voltage of the battery cells is different because polymer batteries
use polymer materials, which can be made into multi-layer combinations within
the cells to achieve high voltage, while lithium battery cells have a nominal
capacity of 3.6V. To achieve high voltage in practical applications, multiple
cells need to be connected in series to form a negative high voltage operation
platform.
5. The production process is different, and the thinner the polymer
battery, the better it can be produced. The thicker the lithium battery, the
better it can be produced. This allows lithium batteries to expand their
applications in more fields.
6. The capacity of polymer batteries has not been significantly improved,
and there is still a reduction compared to lithium batteries with standard
capacity.
