Nickel Metal Hydride No. 5 battery

　　Nickel Metal Hydride No. 5 battery are limited in quantity but not in quality. Research and development breakthroughs have entered a critical stage.

　　Currently, the automotive power battery technologies used are old technologies, and no revolutionary new batteries have emerged. A person in charge of SAIC's new energy vehicle R&D department told reporters that at present, the energy density of power battery technology is still very limited.

　　With the hot sales of new energy vehicles, power battery companies have expanded production and begun to experience rapid growth in performance.

　　On March 21, Tianneng Power released its 2015 annual performance report. Its new energy vehicle power battery sales increased by 209% year-on-year. In order to increase its exposure to this market, the company will expand its battery production capacity to 2.25GWH this year. Companies such as Guoxuan Hi-Tech and BYD have announced plans to expand production on a large scale this year.

　　A person in charge of a battery company previously told reporters that a rough calculation shows that a 1GWH power battery can assemble 40,000 new energy vehicles.

　　Under this circumstance, large-scale production expansion by battery companies is expected to solve the problem of insufficient power battery production capacity. Previously, heads of new energy vehicle manufacturers such as BAIC, JAC, and SAIC told reporters that insufficient supply of Nickel Metal Hydride No. 5 battery, as key components, has begun to limit their new energy vehicle production.

　　However, even if the number of batteries gradually meets the needs, shortcomings in power battery technology and quality are still the biggest limiting factors for the development of the new energy vehicle industry.

　　The reporter learned that during the 315 period, among the complaints about new energy vehicle consumption, the three major issues of cruising range did not match the publicity, the charging degree did not match the publicity, and battery failure caused serious power outage became the hot spots of complaints, and these problems are all related to the battery.

　　Currently, the automotive power battery technologies used are old technologies, and no revolutionary new batteries have emerged. A person in charge of SAIC's new energy vehicle R&D department told reporters that at present, the energy density of power battery technology is still very limited.

　　It is understood that at present, automobile Nickel Metal Hydride No. 5 battery mainly include lead-acid batteries, lithium iron manganese phosphate batteries, lithium iron phosphate batteries, lithium cobalt oxide batteries and ternary polymer lithium batteries. In the current mainstream power battery technology, the main way to increase the storage capacity is to simply increase the number of cells.

　　Increasing the number of cells will lead to reduced safety. Dr. Liu Wenjuan, chief scientist of Microvast Power Company, whose main business is Nickel Metal Hydride No. 5 battery, told reporters that the probability of thermal runaway caused by internal short circuit will increase. Simply put, it increases the probability of spontaneous combustion.

　　Calculated based on the current industry's highest standard of 18650 battery cell quality control rate of 2 ppm, for every one million battery cells produced, 2 will have quality problems. Wu Yang, CEO of Microvast Power, said that for every 100,000 vehicles sold, 1,600 vehicles will have batteries at risk.

　　With battery life and safety still insufficient, the industry is generally looking forward to new technological breakthroughs in Nickel Metal Hydride No. 5 battery.

　　At the end of February this year, Minister of Industry and Information Technology Miao Wei stated at a press conference of the State Council Information Office that the advancement of power battery technology determines the success or failure of vehicle performance, quality, safety and other aspects. In order to promote the development of power battery technology, the Ministry of Industry and Information Technology has teamed up with nine companies and has invested 500 million yuan to establish a power battery research institute or power battery research and development platform.

　　In this context, exploring new power generation technologies is generally considered a business opportunity, and the participation of more companies will accelerate the exploration process.

　　On March 19, Microvast Power released "non-combustible" batteries in Beijing in an attempt to improve battery safety. In addition, there are reports that Hyundai and Kia may release hydrogen fuel cells next year, and companies such as BYD and Guoxuan High-Tech are also expanding their battery research and development teams.

　　As the number of participants increases, we will see rapid breakthroughs in battery technology in recent years. The person in charge of R&D of SAIC New Energy Vehicles said that it is currently in a critical period of breakthrough in power battery technology.

　　However, a person in charge of BAIC New Energy told reporters that as government subsidies decline in the next two years, there will be greater pressure for battery technology advancement. Battery cost accounts for 40% to 60% of the total vehicle cost and is the most critical part affecting the cost of new energy vehicles. The reduction of subsidies will have a more direct impact on the selling price of the entire vehicle.
