Honeycomb Energy has completed the development of the first generation sodium ion battery with an energy density of 110 Wh/kg.

CTOnews.com December 22 news, in today's sodium ion battery technology seminar, honeycomb energy director Jiang Weijun revealed that the company's first generation of sodium ion battery prototype has been completed development, energy density 110 Wh/kg.

In addition, the second generation sodium-ion battery product of Honeycomb Energy is under development, and it is expected to complete the design finalization in the first quarter of 2023 with an energy density of 135 Wh/kg; the sodium-ion battery development of 160 Wh/kg is planned to be completed in the fourth quarter of 2023, and the cycle life is expected to exceed 2000 weeks.

According to CTOnews.com, the energy density of the current mainstream lithium iron phosphate battery is below 200Wh/kg, the energy density of the ternary lithium battery is between 200-300Wh/kg, and the energy density of the existing lithium ion battery is close to the theoretical limit.

It is reported that sodium reserves ranked sixth on the earth, with similar chemical properties to lithium, but due to the larger radius of sodium atoms, the electrochemical potential is relatively low, sodium ion battery energy density compared with lithium ion batteries have inherent disadvantages. The development of sodium ion batteries needs breakthroughs in new sodium storage materials and new electrolytes.

From the perspective of the industry, 2023 may become the first year of mass production of sodium ion batteries. At present, many enterprises such as Zhongke HaiNa, Chuanyi Technology, Penghui Energy, Funeng Technology and Huayang have announced that they will enter the industrialization stage in 2023.
