According to recent reports from the US media, scientists have discovered a new type of battery technology that allows batteries to be recharged hundreds of thousands of times without attenuation. We all know that for mobile phone lithium polymer batteries, the total capacity of charging and discharging 500-1000 batteries will be reduced to only 80% of the previous capacity. After this technology appears, the battery life will increase greatly, for electric vehicles, etc. The field will obviously help.

Researchers have developed a model to determine the lifetime costs of 9 electricity storage technologies for 12 different applications between 2015 and 2050. The model, which predicts lithium-ion batteries to be the cheapest technology in the coming decades.

Conventional lithium ion batteries have reached performance limits. Scientists have now developed a new nanostructured anode material for lithium ion batteries, which extends the capacity and cycle life of the batteries. Based on a mesoporous mixed metal oxide in combination with graphene, the material could provide a new approach how to make better use of batteries in large devices such as electric or hybrid vehicles.

Nowadays, mobile phones are becoming more and more important to our lives. Even some people have reached the level of being uncomfortable with no mobile phones. Such people are not in the minority. Today's mobile phones are non-removable batteries, unlike the previous mobile phones, which can be freely replaced, which means that the battery life is becoming more and more important. Some netizens said that they can't stand the mobile phone's power below 20%. Although many mobile phones have been upgraded on the battery life, mobile phones cannot be changed frequently. Therefore, it is more important to protect the mobile phone battery.

Dramatically longer-lasting, faster-charging and safer lithium metal batteries may be possible, according to Penn State research, recently published in Nature Energy.

What is a lithium battery? It is the battery used by our usual phones, computers, and digital cameras. In recent years, the aviation industry has greatly enhanced the regulations on aircraft on lithium batteries. If passengers are unclear, if they carry too many lithium batteries on the plane, they will cause great disaster at any time. So be sure to know the items about the aircraft with a lithium battery and enjoy a peace of mind.

The price of lithium battery is mainly composed of three major components: battery cell, protection board and outer casing. At the same time, due to the power consumption and current of the electric appliance, the material of the connecting piece between the batteries (conventional nickel sheet, formed nickel piece) The selection of copper-nickel composite sheets, jumpers, etc. will affect the cost. Different connectors may also have a greater impact on cost, and different PACK processes will also affect the cost.

The reason why lithium batteries (Rechargeable) need protection is determined by its own characteristics. Since the material of the lithium battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short circuited, and ultrahigh temperature charge and discharge, the lithium battery assembly will always contain an exquisite protection circuit board.

1, 18650 battery is cylindrical, there is liquid inside, because of battery design and materials, 18650 is suitable for high current, so almost all notebooks, electric cars are designed with 18650 battery; only super notebook, because of energy saving, so can not be used 18650 battery and use polymer lithium battery, especially tablet computer; digital camera because of the charge and discharge of the flash requires large voltage and instantaneous high current, so only 18650 similar battery, but the volume is slightly smaller;

2, the advantages of polymer lithium battery, small size, large capacity, the disadvantage is that the life is shorter than 18650, because of the use of different designs and materials, some have liquid inside, some are dry or colloidal, and high current discharge performance Not as good as the 18650 cylindrical battery, so the need for large-capacity and small-volume electrical equipment, usually using polymer lithium batteries, the most typical performance is mobile phones, tablets and other equipment.

The 18650 lithium battery definition rule is: 18650 battery diameter is 18mm, length is 65mm, cylindrical battery. 18650 lithium battery parameters: voltage: 3.6V (conventional universal battery, for electronic products, low-power electrical equipment, maximum 1C discharge. Can change the discharge current according to the situation); 3.2V (power battery can be customized according to the situation) Charging parameters: 4.2 V
