Following the completion of the joint venture battery company with Ningde Times, Dongfeng Automobile has another child in the power battery fieldOn July 9, Dongfeng Automobile(600006) announced that the company intends to increase its cash capital with 50 million yuan for Haibosi Innovation Energy Technology Co.

Nickel-cadmium battery is operated by the reaction of chemical substances, and chemical materials tend to consume themselves In the environment with high temperature, self-consumption will be more serious, the capacity will be reduced, and there may be leakage and rust.

The wave of new energy vehicles has brought unprecedented new opportunities and demand for lithium batteries is booming The diaphragm is an important part of the lithium battery.

Classification of lithium batteries 1, according to the internal material lithium batteries are usually divided into two categories: Lithium metal batteries: Lithium metal batteries generally use manganese dioxide as a positive material, lithium metal or its alloy metal as a negative material, and batteries using non-aqueous electrolyte solutions Lithium-ion batteries: Lithium-ion batteries generally use lithium alloy metal oxides as positive materials, graphite as negative materials, and batteries using non-aqueous electrolytes.

Voltage: 416-4 .

At present, a number of power cell single core energy densities developed by the Chinese Academy of Sciences have reached 300 W/kg or more, ranking the world's advanced level; Lithium batteries have entered the scale application stage from the core technology in China, which will provide important technical support for the development of long-haul electric vehicles, drones and deep-sea exploration How important is the energy density of the battery? Experts say the range and reliability of a pure electric vehicle depends largely on the energy density inside the battery.

Recently, Yulong shares issued the "Notice on the Increase of Registered Capital of Ningxiahanyao Energy Storage Materials Co, Ltd.

With the help of subsidies, the production and sales of new energy vehicles in China have continued to grow Thus, the rapid development of the lithium power industry has been driven.

The battery of electric vehicles currently has two mainstream designs One is represented by Tesilache, who uses a lithium ion battery + a high IQ battery management system to give full play to the advantages of a large energy density of lithium ion.

The super-capacitor scientific name is an electronic double-layer capacitor[EDLC] Unlike traditional nanomedia capacitors that also have high capacitance values, super-capacitors do not use traditional solid electrolytes.
