What is the impact of frequent safety incidents on the future development of lithium-ion batteries?

The new national standard for the revision of the general code for lithium-ion batteries for cellular phones will be officially launched in recent days, according to okoma. Industry insiders said that this means that China's lithium-ion battery industry will face a reshuffle. At present, there are more than 200 mobile phone manufacturers in China, and there are no lack of hand-made small factories.

Last year's Samsung Note7 battery explosion sparked renewed consumer attention. According to the introduction, because the original national standard of mobile phone batteries can not adapt to the development of the current industry, some inferior quality products appear in the market, which to some extent damages the interests of consumers. In order to ensure the healthy development of lithium-ion battery industry in our country, the relevant departments of the country commissioned the Australian Koma Company last year to preside over the revision of the national standard for lithium-ion batteries. At present, the revision work is nearing completion and will be announced in recent days.

The new national standard for lithium-ion batteries will set a high technical threshold in the industry. Only those enterprises with relatively high levels of technology can meet the requirements, and the structural adjustment of the entire industry will become inevitable, according to Dr. Wuhuikang, head of the national standard revision program of the company. Many small artisanal factories will be eliminated, and some companies with considerable scale and technological advantages will have more room for development.

Comments:

Lithium-ion batteries have higher energy than the material stability, and are prone to safety problems. The original national standard for mobile phone batteries can not adapt to the development of the current industry, resulting in the appearance of some inferior quality products in the market, which is prone to safety accidents and damages the interests of consumers.

The introduction of new national standards for lithium batteries will establish a high technical threshold in the industry, and structural adjustment of the entire industry will become inevitable. After the threshold is raised, a situation will be formed where the fittest and the best will expel the inferior currency. In the future, production capacity will be concentrated in large companies with continuous technological progress, and many handmade small factories will be eliminated.

Compared with the Korea-Japan giants, there are a large number of Chinese companies, but the scale is generally small. For example, in 2014, the total supply of 66.465 million kWh in the world, the combined market share of the three companies, Samsung SDI and LG Chemicals in South Korea and Matsushita in Japan, was 45.1 %. Almost half. Only 10 Chinese companies have an annual supply of more than 1 million kWh, accounting for 70.6 % of the total supply of Chinese companies. Among them, the supply of the top three Tianjin lishen, ATL and BYD exceeds 3 million kWh, but the sum of the three is only 10.473 million kWh, less than Samsung SDI.

There is also a significant gap in the quality of lithium-ion battery products. At present, the product acceptance rate of the Korea-Japan giant has reached 1 ppm, that is, of the one million cores produced, the non-conformity rate is only one or not. It is very good that Chinese companies can reach 90 % of the core products, and these 90 % are generally divided into two grades: A products of good quality and B products of inferior quality. Therefore, in the domestic lithium battery industry, it is time to raise a batch and eliminate a batch of time.
