In February 2018, China's lithium ore raw ore imports were about 395,000 tons, up 28% from the previous month; lithium ore concentrates were 75,000 tons, down 265% from the previous month; lithium chloride imports were 418 tons, up 55% from the previous month.

The lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material This type of battery is characterized by the absence of precious metal elements (such as cobalt).

Lithium polymer batteries can be classified into three types according to electrolytes: (1) A gel polymer electrolyte lithium ion battery, which adds an additive to a solid polymer electrolyte to increase ionic conductivity, so that the battery can be used at normal temperature; (2) Solid polymer electrolyte lithium ion battery, the electrolyte is a mixture of polymer and salt, has low ion conductivity at normal temperature, and is suitable for high temperature use; (3) Lithium-ion battery of composite gel polymer cathode material, conductive polymer as the cathode material, its specific energy is three times that of the existing lithium ion battery and it is the latest generation of lithium ion battery Due to various reasons such as technology, lithium polymer batteries are currently concentrated on the research of small current charge and discharge characteristics of small-capacity batteries.

When we are making lithium battery protection boards, we often ask our customers if they need to charge balance So what is the charge balance? Charging equalization, referred to as equalizing charge, is the charging of the characteristics of the balanced battery.

Is the electric vehicle quick charging station harmful to the battery? Will the electric vehicle quick charging station be used to burn the battery? For electric car owners, there is no power supply on the road halfway, which is a depressing thing The rapid and lightweight electric vehicle quick charging station has emerged, which has facilitated the travel of many citizens.

Researchers have developed a new technology that can solve a big problem facing wearable devices: how to supply power? Because the installed battery is too bulky, the shape and size of the wearable device are severely limited To solve this problem completely, some researchers have developed flexible battery-type devices that can be printed directly on textiles.

The lithium battery of electric vehicle usually has at least ten groups of lithium batteries in series or more, and the battery protection board, completely different from the lead-acid battery pack (the number of small, generally no protection board), if there is a failure, non-professional technicians generally cannot solveThe damage of lithium battery pack in electric vehicle generally includes the following situations:1, battery protection board is damaged, the electronic density, generally difficult to maintenance;2, battery protection board in good condition, single individual battery performance becomes poor, find it is not easy;3, battery protection board in good condition, individual battery short circuit, to screen;All in all, after electric lithium battery failure, maintenance difficulties, usually find after-sales, technical personnel to solve by manufacturer, or replace the same model electric lithium battery pack.

On April 23rd, at the second Automakers' Conference on the theme of "New Era· Big innovation ", the domestic car Roewe MARVELX "Electric Intelligent Super Run SUV" was officially unveiled It has 4 seconds to break 100, 0.

According to a report in the May 5 BusinessKorea Beijing time, as the subsidies on Chinese auto makers will end at the end of next, South Korea The battery Manufacturers are increasing investment in China The subsidy policy is aimed at cultivating its battery industry in China, so as to compete with international rivals.

A "lithium battery" is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution With the development of science and technology, lithium batteries have become the mainstream.
