The misunderstanding of many people is the presence of metallic lithium in lithium-ion batteries, but in fact, it is only a lithium-ion compound The compound used on the positive electrode can decompose lithium ions during charging, and the battery with carbon material as the negative electrode.

The National Development and Reform Commission recently announced that it will cancel all foreign-funded ratios in the auto industry in the next five years At the same time, as new energy vehicle subsidies continue to decline, new energy vehicles have entered a period of accelerated industrial adjustment.

In fact, in the field of electronic products, lithium batteries are commonly used in liquid lithium-ion batteries and polymer lithium ions (18650 refer to the battery with a diameter of 18mm and a length of 65mm, a cylindrical battery.

The ternary battery material refers to a composite electrode material formed by co-melting three kinds of electrode materials and theoretically has the characteristics and advantages of each electrode material Lithium nickel cobalt oxide (LiNixCoyMn1-x-yO2) is currently the most mainstream ternary battery material and is considered to be the future development trend.

For hybrid and pure electric vehicles in the medium-term plan, Japan sees solid-state batteries as a hope to reduce demand for cobalt Cobalt resources are being closed up by Chinese companies, and the lithium battery field is being overtaken by Chinese companies.

The size of the current limiting resistor depends mainly on the power of the user's power system If the power of the user's power system is relatively large, the current limiting resistor can be smaller.

The capacity tester is used for the test capacity The lithium battery is available online, and 1.

On July 4th, the “Regulations on Investment Management of Automobile Industry (Draft for Comment)” issued by the National Development and Reform Commission (abbreviation: “Regulations”) brought shocks to the automobile industry The "Regulations" clarify the scope of investment in automobiles, and in many regulations, the definition of investing in new energy vehicles has become a key point that cannot be ignored.

Recently, the National Standardization Management Committee publicly solicited opinions on the first batch of proposed national standards projects in 2016 on its website In 2016, the first batch of proposed standards "Technical Conditions for Four-wheel Low-speed Electric Passenger Cars" is listed.

Lithium batteries are generally classified into lithium metal batteries and lithium ion batteries Lithium-ion batteries are more widely used because of their changeability and high energy density.
