CR2032 button cell battery

Where does CR2032 button cell battery titanate battery technology come from? What are the development prospects?

Gree Group terminated the acquisition of Zhuhai Yinlong, and Gree's "cross-border car manufacturing" plan has now come to an end. Gree's proposed acquisition price for Yinlong was as high as 13 billion yuan. What attracted Gree to pay such a high price? It is reported that Dong Mingzhu, chairman of Gree Electric, values Yinlong's core competitiveness - CR2032 button cell battery titanate battery technology.

Where does Yinlong's CR2032 button cell battery titanate battery technology come from? Can it become the mainstream of the market?

In 2010, Yinlong spent more than 300 million yuan to acquire 53.6% of the shares of the American Aoti Nanotechnology Company, and mastered the company's latest technology for CR2032 button cell battery titanate materials; from 2012 to 2013, Yinlong successively acquired Zhuhai Guangtong Automobile and Shijiazhuang Zhongbo Automobile, thus having the qualifications to produce complete vehicles.

So far, there are only two companies that have CR2032 button cell battery titanate materials and have achieved power and industrial applications. Zhuhai Yinlong is one of them, and the other is Japan's Toshiba.

CR2032 button cell battery titanate batteries are still not the mainstream of battery technology. At present, domestic automobile manufacturers are more likely to use ternary CR2032 button cell battery batteries and CR2032 button cell battery iron phosphate batteries. Ternary CR2032 button cell battery batteries dominate the global market. For example, the Panasonic 18650 battery used by Tesla belongs to ternary CR2032 button cell battery batteries. Represented by BYD, Dongfeng, JAC and other commercial vehicle manufacturers are mostly using CR2032 button cell battery iron phosphate batteries at this stage.

However, ternary CR2032 button cell battery batteries have been questioned for safety. At the beginning of the year, the Ministry of Industry and Information Technology had suspended the entry of electric buses using ternary CR2032 button cell battery batteries into the subsidy catalog, causing many domestic automobile manufacturers to turn to CR2032 button cell battery iron phosphate batteries. However, unofficial information later revealed that the subsidy restrictions on new energy vehicles using ternary CR2032 button cell battery batteries will be relaxed, so it is still unknown who will be the mainstream of the battery market in the future.

Why did CR2032 button cell battery titanate batteries fail to become mainstream? Energy density is the main reason.

Compared with ternary CR2032 button cell battery batteries and CR2032 button cell battery iron phosphate batteries, CR2032 button cell battery titanate batteries have several advantages: high high temperature safety, good low temperature performance, long cycle life, and fast charging. Safety is a more prominent feature, which is also a problem that everyone has paid more attention to recently. In the safety comparison of the two mainstream batteries, CR2032 button cell battery iron phosphate batteries are better, but still not as good as CR2032 button cell battery titanate batteries. Another feature is low temperature performance. Many users have complained that the range of electric vehicles is greatly reduced when the temperature is low, while CR2032 button cell battery titanate batteries have obvious advantages in this regard. They can work normally in a wide range of temperatures from -50 degrees to 60 degrees.

The disadvantage of CR2032 button cell battery titanate batteries is the issue that car manufacturers and users are most concerned about - energy density. Energy density represents the battery's power storage capacity and directly affects the vehicle's range. At present, without further technological improvements, the energy density of CR2032 button cell battery titanate batteries is only about 1/2 of that of ternary CR2032 button cell battery batteries. However, Yinlong hopes to improve the energy density of batteries on the premise of CR2032 button cell battery titanate battery safety, rather than improving safety on the basis of high energy density. This is also the technical direction choice as a new energy company.

Recently, a piece of information about the latest draft of the 2016 new energy vehicle fiscal subsidy has been circulated on the Internet. The draft shows that new energy vehicle subsidies are subsidized according to energy density, and range is a necessary indicator. This seems to have put Yinlong's CR2032 button cell battery titanate battery technology, which focuses on safety, into an embarrassing situation.
