In addition, the innovation of battery system integration technology in the past two years has also significantly improved the energy density of lithium iron phosphate in the battery pack, giving it a new "second spring".

However, in Xiang Yanhuo's view, with the innovation of battery technology and materials, it is expected that by 2028, the cost and safety advantages of lithium iron phosphate will be replaced by other material systems in the field of passenger cars. The application scenarios and technological research and development of lithium iron phosphate batteries in the future still need to be observed.

02. Medium nickel ternary and cobalt free batteries will become the mainstream in the high-performance vehicle market

Regarding the mid range vehicle market, Xiang Yanhuo expects that in the next few years, it will continue to focus on medium nickel high-voltage ternary system power lithium battery technology. The energy density of the battery cell is expected to increase to 240Wh/kg~260Wh/kg.

According to China's understanding of batteries, in 2020, Ningde Times has started to extensively promote the application of single crystal high-voltage 5-series batteries in mainstream new energy vehicle models. For example, the battery products collaborated with Roewe, Geely, and NIO Motors all use medium nickel single crystal 5 series batteries. This type of battery has better economy and safety compared to nickel 8 series products, while also having good energy density.

In addition to Ningde Times, it is understood that many power lithium battery companies such as Xinwangda, Ruipu Energy, and Lingpai New Energy are also applying single crystal nickel materials on a large scale.

According to Xiang Yanhuo, in this field, Ningde Times will continuously explore and develop product cycle life and fast charging capacity to meet more market demands.

At the same time, for the mid-range car market, Ningde Times is also vigorously developing a cobalt free material system, further achieving high energy density (cell energy density above 250Wh/kg), high performance, and optimal comprehensive cost. From the roadmap, Ningde Times expects to launch cobalt free batteries around 2024.
