How to ensure the high safety and quality of the required lithium batteries?

　　For the rapidly developing lithium battery industry, the safety of lithium batteries is likely to directly affect the market fate of many application products, and the impact is indeed serious from the data point of view. In fact, since 2006, there have been many examples of a fire worth 500-600 million U.S. dollars. For lithium battery companies, product safety is life, and safety issues require long alarms.

　　Mr. Norbron, the former CEO of the American Safety Testing Laboratory Company (UL) once said: "In the past, our responsibility was to prevent unsafe products from entering the market. Now our responsibility is to help safe products enter the market." This is not just a word. The change is a change of concept.

　　High safety and high quality products are required by the global market

　　For the rapidly developing lithium battery industry, the safety of lithium batteries is likely to directly affect the market fate of many application products, and the impact is indeed serious from the data point of view. In fact, since 2006, there have been many examples of a fire worth 500-600 million U.S. dollars. For example, the large-scale battery fire and explosion incident of Samsung Galaxy Note 7 in 2016 cost it nearly 700 million U.S. dollars. However, compared to the losses caused by the chain reaction of Samsung Electronics' sales decline, profit decline, and market value evaporating, the consequences of the brand trust crisis are even more serious. For lithium battery companies, product safety is life, and safety issues require long alarms.

　　Today, the domestic power lithium battery industry that has gone through ups and downs has begun to transform and is achieving both quality and quantity improvements. Data shows that in the last five years, the specific energy of power battery cells has doubled, reaching more than 200Wh/Kg, and the unit cost of the system has dropped to 1.4-1.5 yuan/Wh.

　　In addition, my country's planned power battery production capacity in 2017 has exceeded 170GWh. It is estimated that by 2018, the output value of my country's lithium battery cells will reach 144.8 billion yuan, and the power battery industry has become a new growth point for my country's national economy. At the same time, the rapid rise of the global new energy automobile industry, as well as the continuous exploration and growth of energy storage, unmanned aerial vehicles, balance vehicles and other sub-fields, have also provided new research and development directions and profitability for the development of my country's lithium battery industry.

　　However, whether it is the application of power battery products in the fields of domestic new energy vehicles, energy storage, and echelon utilization, or the "going global" of domestic lithium battery products, "safety and standardization" has always been a topic that the industry cannot avoid. Therefore, how to build a unified standard system and improve product safety; and how to adapt to the corresponding standards in overseas markets and expand product sales markets require domestic lithium battery companies to think and plan ahead of time.

　　Complex application security issues

　　When it comes to safety, one has to mention the probability of accidents. In fact, the probability of lithium battery accidents we usually talk about is that under relatively mild conditions, if it is in electric vehicles, including vibration, collisions, etc., the probability will be greatly improved. The safety of lithium battery applications is a comparison. complicated question.

　　Not long ago, the American AAA insurance company stated that the frequency of claims and the cost of compensation for Tesla ModelS and ModelX are relatively high compared to cars of the same class. Therefore, the company is considering increasing the insurance rates of the two models mentioned above. Although this is only aimed at a Tesla car company, the impact it has caused is global in scope.

　　The United States is known as the "country on wheels". The automotive industry is mature and developed. China has learned from the United States in many aspects of the industry, such as the new energy vehicle point system. If Tesla is really required to "pay more insurance costs", it will inevitably affect the insurance costs of electric vehicles in China.

　　There are many safety issues in the application of lithium batteries, such as insurance costs and accident liability division, but the reality is that lithium batteries that have safety accidents have passed safety certification before. Therefore, we found that there is not much correlation between strict security testing methods and the occurrence of security accidents, which is a very headache.

　　In addition, domestic lithium battery products "going out" must be "going up". Companies not only sell products, but also sell word-of-mouth and high-end brands. How to achieve this? These are all problems that need to be solved urgently.

　　Based on the strong needs of industry enterprises and the consideration of the healthy development of the industry, UL and the Power Battery Application Branch of the China Chemical and Physical Power Industry Association will jointly sign a memorandum of understanding on cooperation in the UL Suzhou laboratory, and cooperate strongly. During the period, there will be special seminars such as "Introduction to UL Battery Global Access Services", "Battery Safety Risks and Case Sharing", and UL chief engineers and senior R&D experts will bring standard-related market information and industry trends.

　　Through in-depth communication with battery companies and vehicle companies, the conference will discuss the feasibility of domestic lithium batteries entering the international market, UL power battery related standards, power batteries and energy storage batteries in the field of safety and environmental protection, and technical bottlenecks. Communicate and discuss the direction of lithium battery standardization.
