What are the differences between lithium batteries and lithium ion batteries?

As smart phones and other digital products more and more popular, power range becomes most people's needs! The emergence of mobile power supply helps mobile phone, tablet power provide a long life, and it becomes the necessary digital technology products for business and travel,.

Sometimes, however, feel, a charging power with faster or charging treasure life wasn't up to individual needs. It's like charging the battery on the treasure for internal use.

In general charging treasure, will use two types of batteries, a kind of is lithium ion batteries. There are a lithium polymer battery。

1. The lithium ion battery is characterized by light weight, easy to carry, use lithium ion transfer to complete charge and discharge, general with mixed lithium metal oxide as an electrode. It can be recharged, many mobile phone and computer batteries, are generally lithium ion batteries. This kind of battery to stay away from heat source, prevent sun point-blank, charging appropriately, but not with, who will take care of the battery has greatly improved durability.

2. Lithium polymer battery is characteristic of high energy density, can be ultra-thin, and its own internal material is solid, or colloidal solids, under the condition of the battery broken, does not leak liquid. And the plasticity is very strong, can adapt to different design needs. Under the same circumstances, lithium polymer battery performance 10% higher than the lithium ion battery, but the relative production cost is higher also.

Green vegetables radish, of course, his taste, everyone has his be fond of, choose their favorite charging treasure, but after I read this, you should know how to choose suits own, a lot of people in choosing a charging treasure, may look at the size, commonly, after all, is too big, because it's heavy, go out is not convenient to carry, especially for girls, to practical, mobile phone charge it with electricity, several times. When choosing to buy charging treasure, therefore, should according to their own specific needs to choose the appropriate, to consider the practicality, portability, effective capacity, as well as the shape and so on various aspects, combined with their own needs, looking for a good focus, to choose their own satisfaction of charging treasure, meet your specific needs.

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. The lithium ion battery and lithium polymer batteries which good? Look small make up analysis for everyone.

1, the fundamental difference is the raw material

This is the different performance of total root. Polymer battery refers 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, shaping the difference

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, manufacturing process

Lithium polymer battery, the thinner the better production batteries are 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.
