What is the lithium battery box lithium ion battery?

Lithium batteries are a kind of lithium metal or lithium alloy as a negative electrode material. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very high. The negative electrode of the lithium ion battery is an intercalated structural materials such as graphite. In the battery, lithium ions move in the positive and negative electrodes, so it is much safer than the lithium battery. More , lithium-ion battery and lithium polymer battery,the lithium ion battery electrolyte is a liquid, and the electrolyte of the polymer battery is gel or solid, which is safer.

What is the difference between a lithium battery, a lithium ion battery and a lithium polymer battery?

First of all

Our current lithium battery, according to the scientific name, should be called lithium secondary battery, there is a corresponding negative electrode material, and lithium primary battery is different, primary battery is mainly lithium is the other pole, this type of battery generally uses liquid electrolyte, nowadays Mainly based on LiPF6, LiClO4 is dissolved in DMC: EC (v: v = 1:1) electrolyte, and some have been modified, but still liquid battery.

Polymer lithium battery, from the perspective of the internal material of the battery, mainly the internal electrolyte is a polymer, here is generally a gel electrolyte and a solid electrolyte, if not mistaken, Koreans have published PEO-ionic liquid as electrolyte The gel-like battery, I don't know if it is used on GalaxyRound or LGGFlex.

Second

The lithium polymer battery box lithium battery is slightly different in packaging. The lithium battery is generally a steel shell (18650 or button type 2320), and the lithium polymer battery is packaged in an aluminum plastic packaging film, that is, a soft pack battery.

Of course, lithium batteries are all solid electrolytes such as LiPON, NASICON, Calcium Titanium, LiSICON, ceramic electrolytes with high conductivity or amorphous materials. If you want to classify, you should probably classify them in lithium. In the secondary battery, but this is already an extension of the concept.

Finally, lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain metallic lithium. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium batteries, lithium ion batteries and lithium polymer batteries are different in principle.

A lithium polymer battery refers to a lithium ion battery that is all solid or gel is too electrolyte. Generally, an aluminum-plastic composite film is used as a packaging material. There are currently only two real lithium polymer batteries in the world. One is Sony in Japan and the other is ATL in China.

A lithium battery generally refers to an aluminum shell battery, the electrolyte is in a liquid state, and the outer packaging material is an aluminum shell.

Lithium polymer batteries are safer than lithium batteries. Lithium polymer batteries are upgraded products of lithium ion batteries. Compared with the current popular lithium-ion battery, it has the advantages of large capacity, small size (thin), and safety (no explosion). However, due to the time required for the replacement of the entire industry chain, its cost (cost) is still relatively high, and it is only used in high-end digital products (ultra-thin notebook computers, etc.).

It is foreseeable that in the next 5-10 years, lithium polymer batteries will replace the existing lithium-ion batteries! In fact, the popularity of lithium polymer batteries in countries such as Japan and South Korea, which are more developed in the electronics industry, has reached a certain level. Level, but China is still relatively backward in this respect, let us wait and see! Waiting for the future, the use of lithium polymer battery mobile phones is cheap, I must replace this more secure mobile phone (battery)!

Lithium polymer battery (Li-polymer, also known as polymer lithium battery): It has a variety of obvious advantages such as high energy density, smaller size, ultra-thin, light weight, high safety and low cost. battery. In terms of shape, the lithium polymer battery has an ultra-thinning feature and can be fabricated into a battery of any shape and capacity in accordance with the needs of various products. The battery can reach a minimum thickness of 0.5 mm. Compared to lithium-ion batteries, lithium polymer batteries have the following characteristics:

1. No battery leakage problem, the battery does not contain liquid electrolyte inside, using colloidal solids.

2. Can be made into a thin battery: with a capacity of 3.6 v400mah, the thickness can be as thin as 0.5 mm.

3. The battery can be designed in a variety of shapes.

4. The battery can be bent and deformed: the polymer battery can be bent up to about 90°.

5. A single high-voltage: liquid electrolyte battery can only be connected in series with several batteries to obtain a high voltage, and the polymer battery can be made into a multi-layer combination in a single piece to achieve a high voltage because it has no liquid.

6. The capacity will be twice as high as the same size lithium-ion battery.

1. ordinary lithium-ion battery Lithium-ion battery commonly known as "lithium battery", is currently the best comprehensive battery system. The negative electrode of a lithium ion battery is a carbon material such as graphite. The positive electrode is a lithium-containing transition metal oxide.

(1) Advantages of lithium ion battery:

1 The working voltage is high, and the working voltage of the lithium ion battery is 3.6 v, which is three times the working voltage of the nickel cadmium and nickel hydrogen battery.

2 is higher than energy. The specific energy of lithium-ion batteries has reached 140 wh / kg, which is three times that of nickel-cadmium batteries and 1.5 times that of nickel-hydrogen batteries.

3 cycle life is long. At present, the lithium ion battery has a cycle life of more than 1000 times, and can reach tens of thousands of times at a low discharge depth, exceeding several other secondary batteries.

4 self-discharge is small. The monthly self-discharge rate of lithium-ion batteries is only 6 - 8%, which is much lower than that of nickel-cadmium batteries (25 ~ 30%) and nickel-hydrogen batteries (30 ~ 40%).

5 no memory effect. It can be charged at any time as required without degrading battery performance.

6 no pollution to the environment. There is no harmful substance in the lithium-ion battery, which is a veritable "green battery".

2. Lithium polymer battery Lithium polymer battery is a new generation of batteries, which entered the market in large quantities in 1999. Lithium polymer batteries are basically the same as lithium ion batteries except that the electrolyte is a solid polymer rather than a liquid electrolyte. The polymer electrolyte material is a common film composed of a solution in which a host polymer such as an oxide of polyethylene is used as a non-moving solvent. The lithium polymer battery has the advantage that it can be made into any shape and relatively light because it does not contain heavy metals and has a plastic shell that keeps the electrolyte from leaking out. Their performance is good, the ideal state of lithium polymer battery capacity in ideal state up to several thousand mA/h, and more secure. The solid electrolyte acts like a sealed gel that does not easily disintegrate naturally during charging.

3. Comparison of two batteries Lithium polymer battery and lithium ion battery technology can replace Ni-Gd battery. But the price is too high, the market has not yet fully accepted, especially lithium polymer technology.
