Recently, BYD’s secretary-general Li Wei revealed that BYD will expand its ternary lithium battery layout in the future. In 2016, BYD expects battery capacity of 10GW·H, and in 2017, it will add ternary battery of 5-6GW·H. BYD is the world's second largest and largest domestic power battery manufacturer. It has always adhered to the technical route of lithium iron phosphate battery and is the leader in the global lithium iron phosphate battery technology. BYD has also begun to lay out large-scale ternary lithium batteries, which means that the technical route of ternary batteries will dominate in the future. Of course, a product portfolio with more technical features is also conducive to grab market share. 　　 Compared with the lithium iron phosphate power battery, the ternary lithium battery has the advantage of higher specific energy. However, the cycle charge and discharge times are low, and the stability is not as good as that of the lithium iron phosphate battery, and the charging speed is slower. However, with the rapid development of the electric vehicle market, people's comparison requirements are getting higher and higher, and cruising range is almost the most important indicator to measure the technical level of pure electric vehicles. 　　 Previously, China's power battery technology route was dominated by lithium iron phosphate batteries. However, the state also began to lean toward capacity density and cruising range in terms of new energy vehicle policy subsidies, and the number of cycles and stability of ternary batteries was rapidly improved. . China's major automotive power battery manufacturers have begun to lay out ternary lithium batteries: such as AVIC Lithium, Guoxuan Hi-Tech, Ningde era, etc. have laid out the development and production of ternary lithium batteries. 　　 In the global power vehicle market for new energy vehicles, the United States, Europe, Japan and South Korea began with ternary lithium batteries as the main technical route. Japan, South Korea's Panasonic, AESC, LG Chemical, Samsung SDI, and SK are the best in this regard. The most successful combination is the cooperation between Tesla and Panasonic. 　　 Earlier this year, Tesla CEO Elon Musk announced that he would jointly invest 3.7 billion pounds in the Nevada desert to build a battery plant with a capacity of up to 35 GW·H. The capacity of this plant is almost equivalent to the market capacity of the global power battery. And, after production, it will be able to meet the power battery requirements of 460,000 Tesla ModelS, ModelX and Model3, and the battery production cost will be reduced by 30%. 　　 The core of the competition for new energy vehicles is the battle for power batteries. The key to the power battery battle is scale and market share. With scale, it will be competitive in price and continue to expand market share. The battle for the global power battery market has started.
