Classification of lithium primary batteries

Lithium batteries are also called lithium primary batteries. It can be discharged continuously or intermittently. Once the power is exhausted, it can no longer be used. It is currently widely used in electronic products such as cameras that consume less power.

Lithium primary batteries have different configurations of electrolytes used. Its function has been greatly improved. Due to the differences in the specific structure, it can be divided into 8 types.

1. Lithium-manganese dioxide batteries

Lithium-manganese dioxide(Li/MnO2) batteries were developed by the University of St. Drew in the United Kingdom. The internal sub-structures are rearranged and have a variety of structures such as single-layer buttoning, multi-layer buttoning, slender cylindrical, rectangular, carbon wrap or roll cylindrical. Has a higher specific energy; Can provide discharge output from microcurrent, small current, or even large current; Can work within the temperature range of -20 ~ +50 °C; Good sealing and storage performance; The annual capacity drop is about 2 <UNK>, and the capacity loss is relatively obvious after 3 years.

Lithium-manganese dioxide battery is also called lithium-manganese battery. The lithium battery models produced by our company include CR2032, CR2025 and CR2032 lithium-manganese buckle welded feet, CR2025 lithium-manganese buckle welded feet and so on.

(1) Lithium-manganese dioxide batteries are mainly used in small electrical appliances such as stereo radios with headphones, mini-recorders, cameras, multifunctional electronic watches, hearing aids, etc..

(2) Lithium-manganese dioxide battery market Lithium-manganese dioxide battery is the lithium battery with the largest usage and cheap price. The market is gradually expanding and has a good development prospects.

2. Lithium-iodine batteries

Lithium-iodine battery is a kind of solid electrolyte battery with emblem current discharge as its main form. It has the characteristics of small size, high specific energy, good reliability and long life. It is mainly used for buried heart posts and its service life can reach 7 to 10 years.

3. Lithionyl chloride batteries

Lithio-thionyl chloride batteries are typical non-aqueous inorganic electrolyte batteries. The main features are as follows:

(1) Generally up to 300 ~ 400 Wh/kg higher than energy, up to up to 900 Wh/kg;

(2) High open circuit voltage of 3.65 V, operating voltage of 3.3 to 3.4 V, and smooth output voltage in the case of lmA/cm2 discharge;

(3) Higher than power can discharge at a high rate(50 mA/cm), higher than power up to 140W/kg, or even higher;

(4) The high and low temperature performance can work within the range of -50 ~ +60 °C, and the carbon package structure can work in an environment up to +150 °C. Even under the environment of -40 °C, 50 <UNK> of room temperature capacity can still be released;

(5) Poor storage effect. After storage, the starting voltage is lagging behind, the safety is poor, the price is expensive, the corrosiveness is strong, and the environment is polluted.

(6) The models using lithium-sulfite batteries are AA, C, DD and derived 1/2 A, 1/3C, 1/6D, etc.. It has been used in military, industrial, and civilian applications, such as military code equipment, radio frequency pickers, underwater detectors, night vision devices, anti-tank electronic equipment, andspecial power supplies; Various measuring instruments, emergency backup power supply, oil drilling, industrial clocks and watches used in 212 industries; Civilian electronic toys, memory circuits, etc..

4. Lithium-sulphur dioxide batteries

The low-temperature performance is good, and it can still work normally at -54 °C. -40 °C can emit 60 inches of room temperature capacity. It is mainly used in military applications such as transceivers and night vision devices.

5. Lithium-polyfluoride batteries

It is a low-power battery with a long storage life. It is used as a power supply for small calculators, memory receptacles, transceivers, electronic buoys, and electronic watches.

6. Lithium-chromate silver batteries

It is a small battery with a specific energy of up to 800 W/P and a long storage life. It is used in high-reliability, long shelving life and work time of more than 10 years, such as industrial appliances, electronic watches, navigation systems, nerve analgesics and so on.

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

It is a new type of lithium primary battery with a load voltage of 1.5 V, which can be interchanged with conventional batteries, with high volumetric specific energy, good high and low temperature performance and safety. Suitable for radios, small walkie-talkies, etc..

8. Lithium alloy-iron sulfide thermal battery

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