Currently, the energy density of the mainstream ternary battery is generally above 210Wh/kg, while the energy density of the mainstream LFP battery is generally below 180Wh/kg. Therefore, this means that this technical index, once implemented, will have a certain impact on the industrialization of LFP batteries.
At this point, a number of power battery enterprise executives believe that this technical index seems to have touched the "ceiling" of LFP battery energy density, but for more competitive power battery enterprises can be achieved.
For example, Honeycomb Energy's second generation L600 short-blade LFP cell has been developed to increase the single capacity to 196Ah, with an energy density of more than 185Wh/kg and a volumetric energy density of more than 430Wh/L, and is expected to reach mass production by Q3 2022.
At present, the mature mass production of LFP cell energy density has reached 190Wh/kg, the test cell has reached 210Wh/kg, and the plan is to reach 260Wh/kg in 2025.
The company said that its main LFP battery products can achieve energy density above 180Wh/kg, and the main products used for electricity and home energy storage can meet the requirements.
The company has already achieved mass production of LFP cells with a specific energy of 180Wh/kg in 2020, and plans to launch LFP cells with a specific energy of 190Wh/kg in 2021.
As a leader in the power battery market, Ningde Times LFP power battery has been installed on a large scale worldwide, and its energy density exceeds 180Wh/kg without difficulty.
