Because the number of charges is limited, the electricity of the lithium battery should be charged with light as much as possible. However, the experimental table data about lithium battery charging and discharge cycle lists as follows:

　　Cycle life (10%dod):> 1000 times

　　Circular life (100%DOD):> 200 times, DOD is English abbreviation with depth of discharge. It can be seen from the table that the number of charging times is related to the depth of discharge. The cycle life at 10%DOD is much longer than the 100%DOD. Of course, if the relative total capacity of the actual charging is discounted: 10%*1000 = 100, 100%*200 = 200, the latter's complete charging and discharge is still better. Under normal circumstances Charging the principle of charging after the power is used up, but if it is expected that it is not possible to adhere to the entire day of the day, you should start charging in time. Of course, if you are willing to carry the charger to the office, it will be another matter.

　　When you need to charge it to cope with important events that are expected to lead to a busy communication, even if there are still many electricity in the battery, then it is only charged in advance, because there is no real loss of the "1" charging cycle life, which is also the life of the "1" charging cycle, which is also the life. "0.x" is only the time, and often this X will be small.

　　Pay attention to fire prevention with lithium battery

　　Many people may be familiar with lithium -power batteries from their mobile phones. In fact, it is used in many appliances. Needless to say, the advantages of lithium -power batteries, such as high efficiency, light body, and so on are rapidly promoting and applied.

　　Lithium batteries have the advantages of light, efficient, low temperature resistance (-40 ° C), and lithium batteries with a thickness of 0.3mm and stamps can be used for more than 5 years. They are widely used in many high -end appliances and mobile phones.

　　Lithium -power batteries are different from the current manganese batteries and alkaline dry batteries, zinc chloride and potassium hydroxide water -soluble electrolytes. It uses organic solubine lithium power batteries. Material. Compared with the zinc chloride used by general batteries, the lithium metal foil used in the negative electrode is strong and the positive and negative pole voltage difference is large, which improves the working effectiveness of lithium -power batteries.

　　However, lithium -power batteries often occur during use in use. The phenomenon of combustion is often occurred. Light ones affect the use of the host, and the heavy ones will also burn the host to cause fire. Family fire accident caused by lithium -power batteries has occurred in Japan.

　　So why are lithium -power batteries fever and burn? After many materials in lithium -power batteries are in contact with water, severe chemical reactions can occur and release a large amount of thermal energy caused by fever and combustion. The manganese dioxide of the lithium battery can appear fever when only a small drop of water is dipped in. After the chlorine chloride in the lithium battery is in contact with water, the thermal energy is released while generating hydrochloric acid and sulfur dioxide. Several factors make lithium batteries a "fire species" in life. Therefore, people must pay attention to waterproof and prevent waterproof when using lithium battery. Wet. After various hosts are suspended, lithium batteries should be removed and kept in a dry and low temperature to prevent and avoid family fire accidents caused by improper use of lithium batteries.
