The news that BYD successfully developed a new type of battery with high energy density has received considerable market attention. Yesterday, BYD Secretary General Wu Jingsheng told reporters that the battery is planned to be mass-produced next year and will be mainly used in BYD's self-produced vehicles.
At present, the power lithium batteries used in new energy vehicles mainly include lithium iron phosphate batteries and ternary material batteries. The former is used in most of China's new energy vehicles, while the latter is used in Tesla and other models. The newly-developed lithium iron phosphate manganese lithium battery by BYD has added manganese element to the traditional lithium iron phosphate battery, which can be described as the next generation technology of lithium iron phosphate battery.
In terms of energy density, the energy density of traditional lithium iron phosphate batteries is around 90Wh/kg, while that of ternary materials is around 150Wh/kg. According to BYD Chairman Wang Chuanfu, the energy density of BYD's lithium iron manganese manganese battery has been comparable to that of ternary materials, which means that the energy density has been increased by nearly 60%, meaning that the mileage will be greatly improved. This technological breakthrough also caused the market to sigh, "Mom no longer has to worry about the life of new energy vehicles."
A senior industry researcher at a Shenzhen securities company believes that the significance of the new battery is not only to improve the mileage, but also to promote cost reduction.
From the previous price point of view, the price of traditional lithium iron phosphate battery is much lower than the ternary material battery. Because cobalt is a relatively rare metal in ternary materials, the price has been high. In contrast, the newly added manganese element in the new lithium iron phosphate manganese battery is very rich in reserves, so it will still have an advantage in cost.
Not only that, the cost reduction in the application link will become more apparent. "On the one hand, increasing energy density helps reduce the number of on-board batteries. On the other hand, due to the heavier weight of the battery, the battery reduction can also effectively reduce the weight of the vehicle, thereby further saving energy. "The above-mentioned industry sources said, "Currently new The cost of batteries in energy vehicles accounts for more than one-third of the cost, and the reduced cost will be directly reflected in the price of the car and the cost of the car.
Since the introduction of new energy vehicles in the domestic market, prices have always been one of the most important concerns of consumers. At present, new energy vehicles have been competitively priced because they have received both state and local subsidies. However, according to the plan, the subsidies for new energy vehicles will decrease over time.
Last year, the Ministry of Finance and other four ministries issued the Notice on Continuing the Promotion and Application of New Energy Vehicles, which stipulates that the subsidy standard for new energy vehicles will decrease year by year. The subsidies for new energy vehicles of various types in 2014 and 2015 will be subsidized. Standards decreased by 10% and 20% respectively on the basis of 2013. Since then, the rate of decline this year has been adjusted to a decline of 5% and 10% at the beginning of the year.
Therefore, some analysts believe that in this context, the future of new energy vehicles will largely depend on the car company's own cost control capabilities, and the reduction in battery costs will undoubtedly play an extremely important role.
