The reporter learned from the Keda Coal Chemistry Research Institute on the 15th that a special carbon anode material for high-capacity high-density lithium batteries with pure carbon as the main component was introduced in the hospital At present, a new electric vehicle lithium battery based on this material has been officially trial-produced in Chengdu Nanguang New Energy Company.

Lithium batteries and lithium-ion batteries are great technologies that will bring tremendous changes and contributions to the storage and supply of electrical energy worldwide Despite this, the risk of fire (explosion) cannot be ignored.

The process of assembling lithium battery cells into groups is called PACK, and it can be a single battery or a series-parallel battery module Under the background of the new national standard, the demand for lithium batteries is getting larger and larger, and many lead-acid battery companies have also introduced lithium-ion products.

"Safety Technical Conditions for Motor Vehicle Operation" (GB7258) Section 1210.

After the batteries are connected in series, the voltages are added, and the currents are equal, which increases the voltage The batteries are connected in parallel, and the voltage is constant (provided that the batteries with the voltages can be connected in parallel, otherwise the high voltage will charge the voltage low, if the difference is too large, there is also a danger) that the current is equal to the sum of the individual batteries, which is often considered to increase the battery capacity and provide more current.

Fujian Province's 2018 key project, the first domestic and international production of 640GWh of single high-capacity solid-state polymer-powered lithium-ion battery project invested and built by the Fujian Provincial Tendering and Purchasing Group was officially put into operation This project is the result of the 863 Torch Program of the Ministry of Science and Technology of the 14th “6·18” successfully completed by the Fujian Provincial Tendering and Purchasing Group in 2016, and the establishment of Fujian Judian New Energy Co.

New energy has already established electric power as the mainstream development direction, but there are many different standards in battery selection Lithium-ion batteries, fuel cells and lead-acid batteries are widely used in the market.

Recently, in the field of domestic new energy vehicles, BAIC Group has repeatedly reported heavy news: the National New Energy Vehicle Technology Innovation Center settled in BAIC, BAIC Group and Daimler to build Beijing Benz new energy production capacity, and Daimler became a subsidiary of BAIC New Energy Company These big moves clearly explained to the outside world the "leading 2025 strategy" proposed by BAIC Group in 2017, which demonstrates the determination of BAIC Group to work hard and implement comprehensive new energy.

With the end of the transition period of subsidy new policies, new energy vehicles have ushered in a new round of market volume, and the domestic power battery installed capacity ranking has also undergone drastic changes Among them, Xingheng Power has become one of the top ten in China due to its continuous development in the field of logistics vehicles and passenger vehicles.

China's ministry of industry and information technology issued a revised set of safety technical specifications for electric bicycles on April 15, 2019, giving manufacturers an 11-month transition period to upgrade their technology The specification was made public in January this year.
