How to do a good job in lithium-battery fire extinguishing and lithium-battery fire fighting related matters?

Current status of production layout of soft package core

Power lithium battery core packaging situation is mainly cylindrical, Square and soft package . Because of its good safety performance, light weight, large capacity and small internal resistance, soft-pack batteries have become an important choice for power battery technology routes. At present, the domestic soft core has surpassed the cylindrical core and has become the second largest type of power core after the square core. In the future, soft-pack batteries may become the mainstream batteries for new energy passenger vehicles.

The first echelon of global soft package power lithium battery technology is mainly Japanese and Korean enterprises, and there are also many enterprises in China. Foreign companies that produce soft-package power batteries include LG, AESC, etc.. Domestic companies such as Yiwei Lithium, Penghui Energy, Tianjin Shares, Tianjin Jiewei, Beijing National Energy, Kanai New Energy, and Fuoneng Technology.

LG Chemistry: The world's leading soft package enterprises, the positive pole mainly takes the three-way route. LG chemically powered battery positive electrode material is mainly ternary NCM, using a stack type soft package design. According to LG's plans for chemical power cell production capacity, the company's power battery production capacity will meet the world's 50,000 electric vehicles in 2016, and the company's production capacity will meet the demand for 200,000 electric vehicles by 2020. Sales of LG chemically-powered batteries are growing steadily, and shipments of LG chemicals are expected to increase significantly to around 4 GWh this year.

AESC: The power battery adopts a soft package design and the positive electrode material takes the lithium manganese acid route. The current mainstream route in the international market is the development of high-nickel ternary materials. Although lithium manganate is relatively cheap, but the energy density is low, the recycling performance is poor, compared to lithium iron phosphate and triplet material has no outstanding advantages, because the positive pole route choice of lithium manganate causes AESC to face the risk of being eliminated from the market.

Guoneng Battery: Production capacity will reach 11 GWh by the end of this year and is expected to reach 25 GWh by 2020. The energy density of the battery pack produced by the National Energy Cell has reached 125wh/kg in 2016, and the energy density of the three-way mass production has reached 200wh/kg. It is expected that by the end of 2017, the monomer density of NNEU lithium iron phosphate batteries will be 180 Wh / kg, and the ternary product will exceed 240 Wh / kg.

Voneng Technology: The existing production capacity is 2.5 GWh. The expansion capacity of the second phase of the project will be completely released by the end of 2017, and the total production capacity will reach 5 GWh. The third phase of the 10GWh project is also in rapid progress and is expected to be phased in in 2018. The company began mass production of 220Wh/Kg power batteries at the end of 2014 and will launch 240Wh/Kg new products by the end of 2017.

Kanai New Energy: The current production capacity is 0.78 GWh, of which the production capacity of the Shanghai base is 0.24 GWh and the production capacity of the base is 0.54 GWh. At present, various production bases are being expanded. After the planned expansion is completed, the production capacity of the Shanghai base can reach 0.45 GWh, the production capacity of the Nanchang base can reach 0.74 GWh, the production capacity of the Liuzhou base can reach 2GWh, and the production capacity planning of the Nanjing base can reach 4GWh in the first phase., the second phase 6GWh, is expected, Up to 10 GWh production capacity by the end of 18 years. The main attack is the three-way soft pack passenger car power battery. At present, the production of the NCM111 three-part soft pack battery has an energy of 170Wh / kg, and the 36-hour three-part soft pack battery has an energy of 220Wh / kg. At the same time, it is accelerating the Advancement of 811 system batteries with a specific energy of 250 W/kg.

JV Power: Focus on the production of polymer lithium-ion batteries, using a soft packaging process, the material system includes three elements and lithium titanate. The company has currently produced a three-part soft-pack battery with a specific energy of 210WH/Kg. On the basis of improving battery safety, it is expected that the company's soft-pack battery single energy density can reach 300WH/Kg in 2020, and Pack can reach 220WH/Kg after forming a group; Lithium titanate batteries have a single energy density of 110 WH/Kg or more. In terms of production capacity, JV Power's planned production capacity for 2017 is 1.6 GWh, which is currently in full production, and its products are in short supply. Therefore, the company will gradually increase its production capacity based on market expectations and is expected to increase to 10 GWh by 2020.

Penghui energy: Penghui energy soft package power core production line existing production capacity of 1GWh, daily output of 10,000, the future will increase steadily with the expansion of market size.

Tianjin Shares: The new production capacity base of Foshan 4GWh has started construction, mainly soft-pack batteries. The first phase of the project will be put into production at the end of the year, with a production capacity of 2GWh, mainly with a 32Ah core of three yuan, and its single energy density can reach 210Wh / Kg.

Billions of lithium weft can: add 1.0 GWh soft pack ternary batteries in the first quarter.
