What does lithium cell mean?

Lithium cell is not lithium battery.

General lithium-ion batteries in general contain two parts: the lithium batteries + control chip.

Lithium battery is the carrier of stored energy, and the control chip is an important part of control, such as charging and discharging lithium batteries work. If there is no control chip only batteries, lithium-ion batteries you can't control current charge and discharge voltage, could be instantly destroyed even explode. So the control chip is the necessary configuration to safe use lithium batteries. Of course there are some appliances bring chips, can directly use lithium batteries, power supply, such as some advance protection chip is used18650 battery electric batteries (lithium) strong light flashlight.

Refers to a single electrochemical batteries contain positive and negative, are generally not used directly. Different from battery protection circuit and shell, can be used directly.

The composition of lithium ion secondary battery charge is this: batteries + protection circuit board. Rechargeable batteries remove protection circuit board is the batteries. He is battery part of rechargeable batteries. The quality of the batteries directly determines the quality of rechargeable batteries.

Mobile phone panels removed the shell, and then remove the panels in the protection of the circuit board is the lithium batteries.

Batteries are divided into aluminum shell batteries, batteries, soft packages (also called "polymer batteries") and cylindrical batteries. Usually phone batteries used for aluminium shell, batteries, bluetooth and other digital products with soft packages batteries, laptop battery series parallel combination of using cylindrical batteries.

Small particle size, large specific surface area, color white, high purity, obviously improves the electrochemical performance. You can use titanium acid lithium battery materials and cobalt acid lithium batteries in the material.1:0.05 ~ 0.35 v (vsSCE) showed typical Faraday turns potential range capacitance behavior. So-called constraint capacitance is following the electric double layer capacitors, development get constraint capacitor. Constraint also calls the Faraday quasi capacitors, for Faraday capacitance, the stored charge includes not only the process of the electric double layer on the storage, and include ion in electrolyte in the electrode active material due to the REDOX reaction will charge storage in the electrode. The electrolyte ions, general of H and OH - in the applied electric field under the action of diffusion in the solution to the electrode/solution interface, and then through the interface of the electrochemical reaction to enter the body to the electrode surface active oxide phase; Due to the electrode material used is a larger specific surface area of the oxide, so there will be quite a few such electrochemical reactions, a large number of electric charge is stored in the electrode. Discharge when these into oxide ions can return to the electrolyte, at the same time the release of the stored charge by external circuit, which is Faraday quasi capacitor charging and discharging mechanism. Say clearly, constraint capacitance is countless small electric double layer capacitance.2: in the same current density (ma/cm2), increase the specific capacity (method/g).3: reduce self-discharge rate, has the good cycle life.

"Lithium battery", is a kind of lithium metal or lithium alloy anode materials, the use of water battery electrolyte solution. Lithium battery as early as 1912 by GilbertN. Lewis is put forward in this study. In the 1970 s, M.S.W hittingham and began to study are put forward lithium ion batteries. Due to the lithium chemistry is very lively, making lithium metal processing, storage, use, very high demand on the environment. So, the lithium battery has not been applied for a long time. With the development of science and technology, the lithium battery has now become the mainstream.

Lithium battery can be roughly divided into two categories: lithium battery and lithium ion batteries. Lithium ion battery does not contain lithium metal state, and can be recharged. The fifth generation of rechargeable battery product lithium battery was born in 1996, its security, specific capacity, self-discharge rate and cost performance is better than that of lithium ion batteries. Because of its high technical requirements limit, now only a few countries in the production of this kind of lithium battery.

Lithium battery:

Lithium batteries are generally use lithium manganese dioxide as positive pole material, metal or its alloy metal anode materials for batteries, the use of water electrolyte solution.

The basic principle of lithium battery

The basic principle of lithium battery

Discharge: Li + MnO2 = LiMnO2

Lithium ion battery:

Lithium ion batteries are generally use lithium alloy metal oxide anode material, graphite as the cathode material, using nonaqueous electrolyte battery.

For the charge on a positive response

LiCoO2 = = Li (1 -) x CoO2 + XLi++ Xe - (electronic)

For the charge on a negative reaction

6C+XLi++Xe-=LixC6

Rechargeable batteries overall reaction: LiCoO2 + 6 c = Li CoO2 + LixC6 (1 - x)

The anode

The anode materials: many optional battery anode materials, mainstream products with lithium iron phosphate. The positive materials of the different control:

The earliest application of lithium-ion batteries are in the cardiac pacemaker. Lithium battery self-discharge rate is extremely low, the advantages of discharge voltage flat, which makes the pacemaker implantation in the human body for a long time operation without recharging the batteries. Lithium batteries tend to have higher than the nominal voltage of 3.0 v, is more suitable for integrated circuit power supply. Manganese dioxide batteries, is widely used in calculators, digital camera, a watch.

In order to develop more excellent performance of varieties, people of various materials are studied, so as to create unprecedented products.

Sony in 1992 successfully developed lithium-ion batteries. Its practical application, make people's mobile phone, notebook, calculator carry type electronic equipment such as less weight and volume.

1, in the 1970 s, M.S.W exxon hittingham using titanium sulfide as the anode material, metallic lithium as negative material, made the first lithium battery.

2, 1980, J.G oodenough discovered cobalt acid lithium can be used as lithium ion battery cathode material.

3, 1982, university of Illinois institute of technology (the Illinois Institute of Technology) R.R.A garwal and J.R.S elman found embedded lithium ion has the properties of the graphite, the process is quick, and reversible. At the same time, made of metallic lithium batteries, much attention has been paid to its safety problems, so people try to take advantage of the characteristics of lithium ion embedded graphite production of rechargeable batteries. The first available lithium-ion graphite electrode successfully trial-produced by bell LABS.

4, 1983 m. hackeray, J.G galaxite oodenough and others found to be excellent cathode material, with a low price, stable and good conductive lithium, guide performance. Its decomposition temperature is high, and oxidation is far lower than the cobalt acid lithium, even if a short circuit, over charge, also can avoid the risk of combustion and explosion.

5, 1989, arjun anthiram and J.G oodenough anionic polymerization is found that the positive will generate higher voltage.

6, 1991, SONY released the first commercial lithium-ion batteries. Subsequently, lithium ion batteries have revolutionized the face of consumer electronics products.

Padhi and Goodenough discovered 7, 1996 has olivine structure of phosphate, such as lithium iron phosphate (LiFePO4), more superiority than traditional cathode material, therefore has become the mainstream of the anode materials.

As digital products such as the widespread use of mobile phones, laptops and other products, lithium-ion battery with excellent performance is widely used in such products, and gradually to other areas of application development products. In 1998, Tianjin institute of power began commercial production of lithium ion battery. Traditionally, people call the lithium ion battery is lithium battery, but the two batteries are not the same. Lithium ion battery has become the mainstream.
