Comparing lithium ion battery and polymer battery, which one is better?

With the continuous improvement of new and high technology, but also because of energy conservation and environmental protection requirements, more and more energy conservation and environmental protection products have been applied to the market, in terms of battery market, lithium battery with a variety of advantages quickly replace conventional lead-acid batteries, become the main force of energy storage market.The classification of the lithium battery has a lot of, the ternary material, lithium iron phosphate material, lithium ion, iron, manganese acid polymer lithium battery such as species.then lithium ion batteries and polymer lithium battery which good?Look small make up analysis for everyone.

Lithium ion battery and lithium polymer battery which good

1, the fundamental difference is the raw material

This is the different performance of total root.Polymer batteryRefers to the positive electrode and negative electrode or electrolyte components in at least one use of polymer materials.The mean molecular weight of polymer, and its corresponding is the concept of small molecules, polymers with high strength, high toughness and high elasticity.The current research and development of polymer materials is mainly used in the anode and electrolyte polymer batteries.(1) polymer battery cathode material in addition to using lithium battery of inorganic compounds, can also use conductive polymers;(2), polymer battery electrolyte with polymer electrolyte (solid or colloidal and organic electrolyte, lithium battery electrolyte (liquid or gel)

2, stay in shape

Polymer battery can be thin shape, any size and any shape, the reason is that the electrolyte can be solid colloidal rather than liquid lithium battery electrolyte is adopted, need a solid shell as secondary packaging for electrolyte.Therefore, it also makes the lithium battery increases the part weight.

3, safety

The current polymer is more soft package battery, USES the aluminum membrane as enclosure, when the internal organic electrolyte, not explode even liquid is very hot, because the polymer battery aluminum-plastic film with solid or colloidal without leakage, just natural fracture.But if anything is not absolute, instantaneous current is enough big, short circuit, the battery or burst spontaneous combustion is not impossible, mobile phone and tablet computer security accidents are caused by this situation.

4, cell voltage

The adoption of polymer materials, polymer battery can be combined in batteries into multi-layer high voltage, and nominal capacity lithium battery batteries is 3.6 V, to achieve high voltage in practical application, you will need to be together multiple batteries in series to form the ideal high voltage work platform.

If the above several characteristics compared to polymer battery and lithium battery which good, then the conclusion is certain, however, in the market or the application of the subject status of lithium-ion batteries, this suggests that the lithium battery also has a comparative advantage, we continue to compare.

5, and electrical conductivity

The solid electrolyte ion conductivity polymer battery is low, at present mainly joined some additive makes it a gel electrolyte, to improve the electrical conductivity.It also increased the ion conductance, just don't like the electrical conductivity of lithium-ion batteries to keep a stable value, without the influence of auxiliary materials quality.

6, capacity,

Polymer battery capacity is not effective to promote, compared with the standard capacity lithium battery has reduced.

7, the manufacturing process

Lithium polymer battery, the thinner the better production batteries as thick as possible production, which makes the lithium battery more scalable in application fields.

8, price

It was decided they are key factors of market capacity, at present, polymer battery on the market price is generally higher than that of lithium battery, this affects the market capacity, the former and the latter is the ratio of 1:9.
