In the context of rising raw material prices, my country's power lithium-ion battery industry has withstood the pressure and once again achieved a good result of doubling its performance. According to the data released by the Power Li-ion Battery Application Branch, from January to November this year, the installed capacity of power lithium-ion batteries in the Chinese market was about 128.3GWh, a year-on-year increase of 153.1 percent , and the annual installed capacity is expected to reach 150GWh.


Attack "big and strong"


Since 2015, my country's new energy vehicle production and sales have ranked first in the world for six consecutive years, and domestic brands have risen rapidly. According to the statistics released by the my country Association of Automobile Manufacturers, from January to November this year, the new energy vehicle market was still hot, and the production and sales volume reached a new high.


In addition, the penetration rate of the new energy vehicle market has also increased rapidly this year, from 5.4 percent last year to 12.7 percent today. An important factor is the substantial increase in the proportion of private consumption, which provides strong support for the increase in sales of new energy vehicles. This also shows that with the continuous maturity of power lithium-ion battery technology, consumers' acceptance of new energy vehicles has become higher and higher, and the new energy vehicle market has shifted from policy-driven to market-driven.


Gao Yanmin, yav dhau los tus thawj coj ntawm Consumer Goods Industry Department ntawm Ministry of Industry thiab Information Technology, tau hais tias txoj kev loj hlob ntawm lub zog tshiab tsheb kev lag luam tau ua rau muaj kev vam meej sai ntawm lub zog lithium{0}}ion roj teeb kev lag luam. Niaj hnub no, lub zog lithium- ion roj teeb cov khoom siv thev naus laus zis tau tsim thiab tsim kho tshiab, thiab cov txheej txheem thev naus laus zis tau hloov kho tas li, thiab cov nqi tsim hluav taws xob tau txo qis ib xyoos ib zaug. Nws tuaj yeem hais tau tias kev nce qib ntawm kev lag luam tsheb tshiab lub zog yog qhov sib cais los ntawm kev pab ntawm lub zog lithium - ion roj teeb.


Statistics from the Power Li-ion Battery Application Branch show that in the first 11 months of this year, the market share of the top 10 companies in my country's market by installed capacity reached 92 percent , of which 9 are independent brands; among the top 10 companies in the global market by installed capacity, Chinese companies occupy 6 seats.


In this regard, Liu Yanlong, Secretary-General of my country Chemical and Physical Power Industry Association, pointed out that in a fully open and competitive market, my country's top battery companies are in the world's first group in terms of product research and development, technological breakthroughs, cost control, and service capabilities. Achieving the goal of "big and strong".
