Overview of Lithium polymer battery and lithium-ion battery for lithium-ion batteries

In real life, people may put lithium batteries and lithium-ion batteries because they are a concept, but different mutual inheritance and development of each other's relationship. The so-called lithium battery is a lithium ion battery in which a battery uses metallic lithium as a negative electrode active material, and the anode and cathode of the system use two different lithium compounds, which are capable of reversibly intercalating and deintercalating lithium ions. The common point between lithium batteries and lithium ion batteries is that metal oxides and sulfides act as anodes, organic solvents and inorganic salts are electrolytes, and lithium and lithium ion batteries are a developing process. The lithium battery uses lithium metal or a lithium alloy as a positive electrode material, and the chemical reaction is a redox reaction. After that, Sony developed a lithium battery cathode material with a carbon material as a negative electrode and a lithium battery with a lithium-containing composite material. Lithium ions, not lithium metal, are involved in the charging and discharging process of lithium batteries. This is a lithium ion battery. Strict, lithium and lithium-ion batteries operate differently. A lithium battery is a primary battery suitable for continuous or intermittent discharge. Some lithium batteries can be used as storage devices, and can be used repeatedly in wind power, hydropower, solar power stations, and other lithium battery batteries. Currently, lithium ion batteries are lithium batteries. The application of lithium and lithium-ion batteries is different: lithium batteries with lithium metal as cathode and MnO2 or thionyl chloride as anode, mainly used for military and civilian, small household appliances, but widely used lithium batteries: mobile phones, video cameras, Cameras, laptops and electric cars. In terms of development trends, the application range of lithium ion batteries has become wider, and lithium and lithium ion batteries of lithium batteries have become narrow. The fundamental difference between this is the presence of lithium ions rather than the lithium metal lithium ion battery. Therefore, lithium ion batteries are also known as "rocking chair batteries.

The lithium battery cells are combined into a multi-cell lithium battery. A lithium battery is named after a lithium battery number. For example, a combination of three units is called a three lithium battery. There are three combinations: series, parallel and series &; parallel multi-cell lithium batteries, most of which are used in laptops. The following explanation is based on a multi-cell lithium battery for laptops, laptop batteries with odd-table, 3 and 9-core combinations and 4, 6, and even a combination of cells and 12 cells. Different multi-cell combinations result in different voltages and capacities. In general, more batteries, longer life and standby time, but the negative impact resulting in higher prices and poor performance is because multi-cell combinations require high battery consistency and consistent work. The following explains how to determine a multi-cell battery by referring to the 3 and 6-cell lithium batteries as an example. 3 marked 11.1v/2200mah lithium battery. This is because of the series combination of three 3.7V lithium batteries, resulting in a total voltage of 11.1V (3.7 x 3) and a capacity of 2200 mAh (2200 x 1). The 3-cell lithium battery is 11.1v/4400mah. This is because the six 3.7V lithium battery combination is similar in the 3 series and 2 series. At the same voltage, three times the capacity of a 6-cell lithium battery, a 3-cell lithium battery. The root cause of high-capacity lithium battery capacity is 6 to 3battery.multi-cell lithium battery is widely used. However, as mentioned above, more batteries mean higher prices and poorer performance. Taking a laptop battery as an example, 3 and 4 lithium batteries are sufficient for home use because of stable power; 6 and 8 cell lithium batteries are suitable for fixed places due to long standby time; mobile office can consider 9-cell and 12-cell lithium batteries due to long service life.
