What type of battery does lithium battery belong to?

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and can be charged. The fifth-generation lithium metal battery of rechargeable batteries was born in 1996, and its safety, specific capacity, self-discharge rate, and performance price are better than those of lithium-ion batteries. Due to its own high-tech requirements, companies in only a few countries are now producing this lithium metal battery.

Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as a positive material, lithium metal or its alloy metal as a negative material, and batteries using non-aqueous electrolyte solutions.

Basic Principles of lithium battery

Discharge reaction: Li + MnO2 = LiMnO2

Lithium-ion battery: is a secondary battery(rechargeable battery) that relies mainly on lithium ions to move between positive and negative poles. During the charging and discharging process, Li + is embedded and not embedded between the two electrodes: When charging, Li + is not embedded from the positive electrode, the negative electrode is embedded through the electrolyte, and the negative electrode is in a lithium-rich state; When discharging, it is the opposite. Batteries generally use lithium-containing materials like electrodes and are representative of modern high-performance batteries.

Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and batteries using non-aqueous electrolytes.

The reaction on the charging positive pole is LiCoO2 = = Li(1-X) CoO2 + XLi + Xe-(electron)

The reaction that occurs on the charge negative pole is

6C + XLi + Xe-= LixC 6

Total rechargeable battery reaction: LiCoO2 +6 C = Li(1-x) CoO2 + LixC6

The most common household batteries, alkaline batteries, were not recognized by many people until after the 1970s. Compared to some of their common counterparts such as zinc chloride batteries, alkaline batteries are relatively cheap and supply a lot of electricity. In some capabilities, however, their battery life is relatively short and actually not ideal.

Lithium-ion batteries are relatively expensive, but they have the advantages of a lightweight, large capacity, and large energy density. Compared with nickel-metal hydride batteries, lithium-ion batteries are lighter, and the energy ratio is 60% higher. Because of this, the production and sales of lithium-ion batteries are gradually surpassing nickel-metal hydride batteries and becoming one of the main batteries used by digital cameras. In addition, the almost no "memory effect" of lithium-ion batteries and the absence of toxic substances are also important reasons for its widespread use.

The technical status and performance of lithium ion batteries and lithium batteries are relatively good, but the price is slightly higher and the use is more elaborate and complex. In particular, the charger of lithium-ion batteries must be "dedicated" and it can not be used with other batteries. Charger compatibility. Alkaline zinc and manganese batteries, although the unit price is low, consumers can afford it, but their short life span, long-term use makes it difficult for ordinary consumers to bear the cost. In contrast, cadmium-nickel batteries and hydrogen-nickel batteries are currently more mature and reasonably priced batteries in manufacturing technology. If you're using a mismatched battery or are not careful to save, the battery will run out before you take a few photos.

The following methods can save battery usage:

First, avoid using unnecessary zoom operations as much as possible;

Second, avoid frequent use of flash, Flash is large power consumption, everyone tries to avoid using;

Third, it is best to use a viewfinder instead of an LCD when adjusting the composition of the picture. Because most digital cameras consume more power by turning on the LCD screen, turning it off can increase the battery standby time by two or three times;

Fourth, minimize the use of continuous shooting function. Most of the digital camera's continuous shooting features use the built-in cache of the fuselage to temporarily store digital photos. If you use these caches often, you need a lot of power. Therefore, reducing the use of continuous filming and dynamic video shooting functions can greatly help save electricity.

Regarding the battery purchase aspect, we should also pay attention to when purchasing, after all, different types of batteries use different time. It is recommended to use ordinary battery products because of the use of ordinary battery products you can also buy your own rechargeable battery to achieve the latter's effect; The use of dedicated batteries, it is easy to appear that the battery is broken after the special battery trouble. Of course, dedicated batteries have the advantage of being thinner in shape.
