Nano Tungsten Oxide Is Added To The Negative Electrode Of Lithium Batteries And Is Being Used In New Energy Vehicles
In the production of new energy vehicles, the use of lithium anode material containing yellow tungsten oxide can provide energy for the power battery and improve the cost performance of the vehicle.

New energy vehicle lithium anode material contain tungsten oxide WO3 nanoparticles.

In the production of new energy vehicles, the use of lithium anode material containing yellow tungsten oxide can provide energy for the power battery and improve the cost performance of the vehicle.

As far as the new energy vehicle industry is concerned, the battery part is the core of the three-electric technology. According to the relevant personnel, in 2019, the first batch of new energy vehicle battery system energy density of 160Wh/Kg or more, a total of 15 models, respectively BYD, CITIC Guoan, GAC Group, Jianghuai Ting, Ningde Times, PHYLION, DFD, Tianjin Jiewei, Shanghai DLG, Ningbo Viri. The battery systems they developed are all based on ternary batteries. Professionals point out that in the production process of lithium anode materials, adding nano yellow tungsten oxide can make the battery have a higher cost performance, and then improve the competitiveness of new energy vehicles in the international market. The reason why yellow nano-sized tungsten oxide particles are used as lithium anode material is that yellow tungsten oxide has the advantage of higher energy density and lower price.

Nano yellow tungsten trioxide, WO3 powder, is a special inorganic N-type semiconductor material, which can be used to prepare cost-effective electrode materials, that is, the prepared fast charging lithium battery has not only higher electrochemical performance, but also lower production cost.Compared with similar batteries in the market, lithium batteries containing nanometer tungsten powder have a wider range of uses, and can provide sufficient energy for new energy vehicles, power tools, touch-screen mobile phones, laptops and other devices.

Ternary lithium batteries and lithium iron phosphate batteries occupy the mainstream of the market. However, they have some drawbacks, such as limited space for energy density improvement. To this end, scientists focus on the research of anode and cathnode materials.

Technology development trend of lithium cathode materials

Orthosilicate, layered lithium-rich manganese-based, sulfide-based cathode materials are the current research hot. In theory, orthosilicate can allow the exchange of 2 Li+, which has a high theoretical specific capacity, but in the release process, the actual capacity is only half of the theoretical capacity. In addition to high specific energy, layered lithium rich manganese base has the advantage of reasonable price. Before this, it is necessary to find a suitable production method. Sulphur-based cathode materials have an energy density of 2600Wh/kg, but volume expansion is easy to occur in the charging and discharging process, which needs to be improved.

Technology development trend of lithium anode materials

Graphene, lithium titanate and nano yellow tungsten oxide are the most enthusiastic lithium anode materials. Graphene can be used as a negative conductive agent to make composites with positive and negative materials, but it cannot be used in large quantities as an active substance to replace graphite anode materials. Lithium titanate has a long cycle life, up to more than 10,000 times, and can be quickly charged, more suitable for the space does not require energy storage field. Nano yellow tungsten oxide is a special electrode material with a theoretical capacity of 693mAh/g and excellent electrochromic performance. In addition, it has the advantages of low price, abundant reserves and non-toxicity.

In conclusion, nano-sized tungsten oxide WO3 can be used as electrode material and used in new energy vehicles.

Guangzhou Hongwu Material Technology Co., Ltd. is supplying nano yellow tungsten trioxide WO3 in bulk, with a monthly output of more than 2 tons. Driven by new energy vehicles, we are gradually expanding the production line, providing better products for the market, and making a modest contribution to the new energy field.
