Overview of Lithium Battery

Overview of Lithium Battery


Li-ion Asus A42-A3 Battery is a class of lithium metal or lithium alloy anode material, the use of non-aqueous electrolyte solution batteries. First appeared in the lithium battery from the great inventor Thomas Edison, using the following reaction:

Li + MnO2 = LiMnO2

The reaction for oxidation-reduction reaction, discharge.

As a result of the chemical properties of lithium metal is very lively, making lithium Asus Laptop Battery metal processing, preservation, use, very high demands on the environment. Therefore, long-term lithium batteries have not been applied.

However, lithium batteries have become the mainstream.

The characteristics of lithium batteries

1, with a higher power-weight ratio, energy volume ratio;

2, high voltage, single-cell lithium battery voltage of 3.6V, approximately equivalent to three nickel-cadmium or nickel-metal hydride rechargeable battery voltage of the series;

3, Hsiao Ke prolonged storage of self-discharge, which is the most prominent advantages of the battery;

4, poor safety performance lithium batteries;

What is the specific energy it? Than energy refers to the unit weight Laptop Battery or unit volume of energy. With specific energy Wh / kg or Wh / L to indicate. Wh is a unit of energy, W is watts, h is the hour; kg is 1000 grams (weight units), L is liters (volume units).

The structure of lithium batteries

Lithium batteries usually have two kinds of shape: cylindrical and long square.

Battery internal spiral winding structure, with a very elaborate and highly permeable material in polyethylene film isolate positive and negative interval formed. Cathode including lithium and cobalt dioxide, lithium-ion composition and the collector current is composed of aluminum thin film collector. Formed by a sheet of carbon anode materials of lithium-ion collector and copper thin film composed of the composition of the current collector. Rechargeable batteries with organic electrolyte solution. PTC is also equipped with safety valves and components, so that the battery in an abnormal state and output short-circuit the battery to protect against damage.

Single-cell lithium battery voltage is 3.6V, the Acer BTP-ARJ1 Battery capacity can not be infinite, therefore, often single-cell lithium batteries and parallel processing, in order to meet the requirements of different occasions.

The application of lithium batteries

As the twentieth century, the development of microelectronics technology, miniaturization of devices has increased, the power put forward a very high demand. Li-ion battery had entered a practical stage of large-scale.

To be applied in the first cardiac pacemaker. As the lithium battery self-discharge rate is very low, flat discharge voltage. Makes the pacemaker implanted in human long-term use is possible.

Lithium batteries are generally higher than the nominal voltage of 3.0 volts, more suitable for Acer BTP-AQJ1 Battery integrated circuit power supply. Manganese dioxide battery, widely used in computers, calculators, cameras, wristwatches.

Now, a large number of lithium batteries used in mobile phones, it can be said to be the largest group of applications.

Study of lithium batteries

In order to develop a performance superior varieties, people of various materials were studied. Thereby creating an unprecedented product. For example, lithium sulfur dioxide batteries and lithium-thionyl chloride batteries is very characteristic. Their is also a positive active material and electrolyte solvent. This structure is only in the non-aqueous electrochemical system, to appear. Therefore, the lithium battery research, but also contributed to Acer BTP-APJ1 Battery the electrochemical theory of non-aqueous system development. In addition to using a variety of non-aqueous solvent, the polymer film was also carried out cell research.

The role of lithium-ion battery

Lithium-ion batteries currently liquid lithium-ion battery (LIB) and polymer lithium-ion battery (PLB) categories. Among them, liquid lithium-ion battery is the Li + intercalation compound as the positive and negative secondary battery. LiCoO2 cathode using lithium compounds or LiMn2O4, negative use of lithium - carbon intercalation compounds. Lithium-ion batteries as a result of the high voltage, small size, light weight, high energy, no memory effect, no pollution, little self-discharge, long cycle life and is ideal for the 21st century energy.

Successfully developed in 1992, Sony lithium-ion batteries. It's practical, so that people's mobile phones, notebook computers and other portable electronic devices greatly reduced weight and size. Greatly extend the usage time. As the lithium-ion Acer Aspire 1300 Battery do not contain chromium, as compared with the nickel-chromium batteries, greatly reducing the environmental pollution.

History of lithium-ion battery

Lithium batteries and lithium-ion batteries in the 20th century developed a new high-energy batteries. This battery Hang wall osprey bran Ren nO2, SOCL2, (CFx) n and so on. 70 years into practical use. Because of its high energy, battery voltage high operating temperature range, long storage life, etc., has been widely used in military and civilian small appliances, such as mobile phones, portable computers, camcorders, cameras and so on, in part to replace the traditional Acer LCBTP03003 Battery.
