A main lithium battery is a type of high-energy chemical battery that is also known as a lithium battery. The negative electrode is metallic lithium, the electrolyte is solid salts or salts dissolved in organic solvents, and the positive electrode active material is metal oxides or other solid or liquid oxidants.
The initials CR and BR, followed by the battery model number, denote the frequently used circular lithium-manganese dioxide (Li-MnO2) and lithium-carbon fluoride (Li/(CFx)n) batteries. The phrase "primary lithium battery" refers to a class of chemical power sources that employ metallic lithium as the negative electrode material.
Maximum pulse operating current of a primary lithium battery
The nominal voltage of a main lithium battery is 1.5V or 3.0V. Primary lithium batteries are available in a variety of shapes and sizes, including button, cylindrical, and rectangular.
Primary lithium batteries offer high specific energy, a long life, and are leak-proof, but they are unsafe. They're mostly found in tiny equipment like cameras and calculators. The cylindrical carbon package type, square stacked type, cylindrical stacked type, cylindrical winding type, and square winding type are the most common structural shapes of lithium batteries.
The lithium-manganese dioxide battery is the most widely used primary lithium battery, and the structure of the button lithium battery is similar to that of the button silver oxide-zinc battery.
The primary lithium batteries currently commercially produced include lithium-iodine batteries (Li/I2), lithium-manganese dioxide batteries (Li/MnO2), lithium-copper oxide batteries (Li/CuO), lithium polyfluorinated carbon batteries (Li/(CF)n), lithium thionyl chloride batteries (Li/SOCl2), and lithium sulfur dioxide batteries (Li/SO2). The lithium-manganese dioxide (Li/MnO2) battery is the most commonly produced lithium battery in China, in button and cylindrical form.
An electrode assembly, a container housing the electrode assembly, and an electrolyte are typically included in a lithium-ion secondary battery. The electrode assembly consists of two electrodes with opposing polarities and a separator. A porous film cluster containing ceramic particles is included in the separator. The porous film is created by gluing particle clusters together using a binder. Sintering or totally or partially dissolving and re-crystallizing ceramic particles create each particle cluster. Ceramic materials having bandgaps are present in the ceramic particles. Particle clusters with a grape-like or thin layer shape can be created by laminating ceramic particles with a flake or thin sheet shape.
A primary lithium battery is a high energy chemical battery commonly referred to as a lithium battery. It uses metallic lithium as the negative electrode, solid salts or salts dissolved in organic solvents as the electrolyte, and metal oxides or other solid or liquid oxidants as the positive electrode active material. The commonly used circular lithium-manganese dioxide (Li-MnO2) battery and lithium-carbon fluoride (Li/(CFx)n) battery are represented by the letters CR and BR, respectively, followed by the battery model number.
