Lithium-iron battery is a high-tech product that replaces the current high-energy alkaline battery. Because of its unparalleled discharge performance, service life and environmental advantages, it has quickly become popular in developed countries and become the third generation of battery after the first generation of carbon battery and the second generation of alkaline battery - lithium-iron battery.
Carbon battery full name: neutral zinc - manganese dioxide dry cell, belongs to the chemical power in the primary battery, is a kind of disposable battery. Because this chemical power device its electrolyte is a paste that cannot flow, so it is also called dry cell, which is relative to the battery with flowable electrolyte. The easiest way to identify: the battery skin type R6 + suffix (five) / R03 + suffix (seven), the biggest advantage is the price is convenient.
Alkaline batteries are also known as alkaline dry cell, alkaline zinc-manganese batteries, alkaline manganese batteries, is the best performance of the zinc-manganese battery series varieties. It is suitable for large amount of discharge and long time use. The internal resistance of the battery is lower, so the current generated is larger than that of ordinary manganese batteries, and the mercury content of the environmentally friendly type is only 0.025%, so there is no need to recycle.
Lithium-iron battery is the third generation of primary battery after carbon battery and alkaline battery, which has many advantages such as excellent discharge performance, wide working temperature range, long storage time, zero pollution, etc. It is regarded as the most ideal alternative for disposable battery in the industry.
The difference between carbon batteries, alkaline batteries and lithium-iron batteries
1, lithium-iron batteries can be charged, alkaline batteries and carbon batteries can not be charged.
2, lithium-iron batteries are divided into milliamps, alkaline TV and carbon batteries are not divided.
3, alkaline batteries weigh more than carbon batteries, such as No. 5 alkaline electricity weighs about 25 grams each, while No. 5 carbon electricity weighs about 18 grams each. Because the shell of alkaline batteries is a steel shell, the shell of carbon batteries for zinc and copper.
4、Alkaline batteries have a circle of negative groove, while the carbon battery here is not
5, compared to alkaline batteries, lithium-iron batteries are not easy to leak, because the electrolyte is completely adsorbed on the diaphragm, and there is no liquidity inside the battery, which will not corrode electronic equipment.
The structure of alkaline batteries is completely opposite to that of acid batteries, the center of the battery is the negative electrode, zinc is in powder form, the positive electrode area is in the outer layer, a mixture of MnO2 and KOH, and the shell is a steel cylinder. Alkaline zinc-manganese batteries overcome the shortcomings of acid batteries storage time and voltage instability, but still disposable batteries. Alkaline batteries are 4-5 times more powerful than carbon batteries and 1.5-2 times more expensive than carbon batteries. Carbon batteries are suitable for use in low-current appliances, while alkaline batteries are suitable for use in high-current appliances.
Lithium-iron battery electrolyte uses organic solvent containing lithium salt instead of aqueous solution. Compared with carbon and alkaline batteries, this new lithium-iron battery eliminates the risk of leakage from the material. In addition to the internal materials, lithium-iron batteries are fundamentally different from carbon and alkaline batteries, the production process is also completely different, and the internal structure of the lithium-iron battery is coiled.
Alkaline batteries, with the advantages of high capacity and low price, occupy half of the dry battery market, both convenience stores and large supermarkets, can see the figure of alkaline batteries. However, alkaline batteries are also criticized for leaking, the electrolyte inside the alkaline battery is strongly alkaline, which has a corrosive effect on metals and plastics, some of the more demanding digital products have begun to abandon the use of alkaline batteries, and switch to the use of non-leaking lithium-iron batteries.
The above is the difference between carbon batteries, alkaline batteries and lithium-iron batteries. These three types of batteries can be described as each advantage, compared to the first generation of carbon and the second generation of alkaline batteries, the third generation of lithium-iron battery advantages are more obvious. It is based on the above advantages, lithium-iron batteries are often referred to as the industry after the carbon batteries, alkaline batteries, the third generation of primary batteries, is currently the most ideal alternative to disposable batteries, but also become a number of countries in the earthquake and wartime emergency package of necessities.
