Tungsten oxide nanowire is an important N-type semiconductor material, which has characteristics of electrochromic, photochromic, absorption, catalysis, etc., and has been widely used in power batteries, chemical sensors, optoelectronic devices and other fields. In terms of power batteries, tungsten oxide is mainly used as a component of multifunctional electrode materials to improve the comprehensive quality of the prepared batteries to make up for the lack of high-end production capacity in the current society.
It is reported that the entry-level pure electric vehicle e-tron 50 quattro recently released by Audi as a low-power version of the e-tron has significantly reduced the performance parameters of the flagship model e-tron, and the power battery capacity has been reduced from 95kWh to 71kWh The cruising range has also been shortened from 417km to 300km. In this regard, relevant persons stated that, first, as the electric vehicle industry continues to heat up, the introduction of low-mileage products may be to meet the needs of users who are gradually derived and segmented; second, it may be due to its battery supplier LG Chemical Caused by insufficient high-end battery supply. After investigation, the latter is the main reason, because of the shortage of LG battery supply, Audi can only delay the launch of the first flagship model e-tron.
In recent years, affected by the new energy vehicle subsidy policy, many battery companies have focused on production capacity and blindly expanded production capacity, but ignored the upgrade of product quality, which has caused the polarization of the power battery market to become more serious, that is, the production capacity of low-end products. Overcapacity, insufficient high-end product capacity.
Fortunately, the discovery of other transition metal compound electrode materials such as tungsten oxide nanowires can be a good part of power batteries, effectively improving the battery's electrochemical performance such as energy density, service life, and charging speed. As a result, tungsten oxide batteries may ease the polarization in the current battery market.
