Introduction of Lithium Primary Battery

Lithium battery is also called lithium battery. It can discharge continuously, and also can discharge intermittently. Once the power runs out, it can no longer be used, and is now widely used in low-power electronics such as cameras.

Lithium battery due to the use of different electrolyte configuration. To its function has very big improvement, because specific structure difference, can divide again for 8 kinds.

1. Lithium - manganese dioxide batteries

Lithium - manganese dioxide (Li/MnO2) battery developed by the university of st. The internal molecular structure is rearranged, including single-layer buckles, multi-layer buckles, slender cylindrical, rectangular, carbon-encased or roll-type cylindrical structures. Higher specific energy; Can provide from small current, small current, even large current discharge output; Can be in - 20 ~ + 50 ℃ temperature within the scope of work; Good sealing and storage performance; Capacity drops by about 2% a year, and it is only after three years that the loss becomes apparent.

Li-mno2 battery is also called li-mno2 battery. The lithium battery models produced by our company include CR2032, CR2025 and CR2032 li-mno2 button type tape welding feet, CR2025 li-mno2 button type tape welding feet, etc.

Lithium manganese dioxide battery is mainly used for small electrical appliances, such as stereo radio with headphones, small radio recorder, camera, multi-function electronic table, hearing aid, etc.

(2) market of lithium-manganese dioxide battery lithium-manganese dioxide battery is the lithium battery with the largest consumption and low price at present, and the market is gradually expanding, with a good prospect for development.

2. Lithium - iodine battery

Lithium - iodine battery is a kind of solid electrolyte battery with the main form of badge current discharge. Mainly used for buried pacemaker, the service life can reach 7~10 years.

3. Lithium - thionyl chloride battery

Lithium - thionyl chloride battery is a typical non-aqueous inorganic electrolyte battery, the main characteristics are as follows:

(1) the specific energy is generally up to 300~400Wh/kg and even up to 900Wh/kg;

(2) high voltage open circuit voltage 3.65v, working voltage up to 3.3 ~ 3.4v, in lmA/cm2 discharge can maintain the output voltage stable;

(3) large specific power can discharge at a high rate (50mA/cm), and the specific power is up to 140W/kg, or even higher;

(4) high and low temperature performance is good in 50 ~ + 60 ℃ within the scope of work, the carbon bag type structure can work in up to + 150 ℃). In - can still be released under normal temperature of 40 ℃ environment capacity of 50%;

(5) poor storage effect. When working after storage, the starting voltage lags behind, the safety is poor, the price is expensive, the corrosion is strong, and the environment is polluted.

(6) the application of lithium - sulfurous acid chloride battery model to have AA type C, DD and derived, 1/2 type 1/6 type a, type / 3 C, d, etc., in the military, industrial and civil applications, such as code of military equipment, radio frequency converter, underwater detector, night-vision goggles, anti-tank electronic equipment,special power supply, etc.; Various measuring instruments used in industry, emergency power supply, oil drilling, industrial clocks and watches, etc. Electronic toys and memory circuits for civilian use.

4. Lithium - sulfur dioxide batteries

Low temperature performance is good, in - 54 ℃ can still work normally, and 40 ℃ can emit 60% of the normal capacity, mainly used in military, such as transmitter-receiver, night-vision units, etc.

5. Lithium - polyfluorocarbon battery

It is a kind of small power battery with long storage life, used as power supply for small calculator, memory, receiver and transmitter, electronic buoy and electronic watch.

6. Lithium - silver chromate battery

Is a small size, specific energy up to 800Wh/P, long storage life of the battery. Application in high reliability, long service life and working time more than 10 years occasions, such as industrial electrical appliances, electronic watches, navigation systems, nerve analgesics, etc.

7. Lithium - copper oxide and lithium - iron sulfide batteries

It is a new type of lithium battery with 1.5v load voltage, interchangeable with conventional batteries, high volume specific energy, good high and low temperature performance and safety. Suitable for radio, small walkie-talkie, etc.

8. Lithium alloy - iron sulfide thermal battery

Lithium activated solid electrolyte batteries, also known as molten salt thermocells, are usually classified as thermocells. With excellent discharge characteristics, it is a new battery system to replace other thermal batteries, even some zinc and silver batteries.
