The exhibition will focus on showcasing global power batteries, energy storage batteries, 3C batteries, charging and swapping equipment and supporting facilities, hydrogen and fuel cells, various battery materials, manufacturing equipment, power and energy storage system solutions.

On May 16, as the highlight of the sodium electricity industry in this exhibition, Betray, a global cutting-edge enterprise of new energy battery materials, released in Shenzhen the hard carbon anode material of Sodium-ion battery - sodium detection 350 and sodium ion battery cathode material - sodium oxide B.
Dr. Li Zikun of the Academia Sinica of Beiteri introduced at the press conference that the specific capacity of the "sodium detection 350" material can reach 350mAh/g, the first charge and discharge efficiency can reach 90%, the specific capacity of the Beina O3B material can reach 145mAh/g, and the compaction density is greater than 3.4g/cc, which will greatly improve the capacity and cycle life of the sodium battery, and significantly improve the charging efficiency and extremely low temperature performance.
Betterly said that the energy density of cell cell equipped with positive and negative electrode materials of Betterly Sodium-ion battery reached 160Wh/kg, four times that of lead-acid battery, and the ultra long cycle was 3000 weeks, six times that of lead-acid battery, realizing a 5-minute fast charge, and it can still be used normally under the extremely low temperature environment of -40 ° C.

Toppon held a new energy product press conference at the International Battery Technology Exhibition (CIBF2023), which announced that the nominal capacity of Sodium-ion battery is 9.0Ah, the nominal voltage is 3.0V, the voltage range is 1.5-4.0V, the energy density is 120Wh/kg, and the cycle life is more than 2500 times. The discharge capacity of the Sodium-ion battery is close to 80% at -40 ℃, which can realize 3C charging and 5C discharge at the same time. The charge time is 20 minutes, and the power can reach more than 90%. Compared with ordinary lithium ion battery, the cost of raw materials of the Sodium-ion battery can be reduced by about 50% for the positive electrode, 20% for the negative electrode, 15% for the electrolyte, 10% for the collector, and about 30% for the total cost of raw materials. Toppon said that in the third quarter of this year, global mass production and delivery will be started. At the same time, Toppon Sodium-ion battery will accelerate iteration in energy density, cycle life and other aspects to meet the growing market demand of customers. From the perspective of long-term planning, by 2025, Toppon Sodium-ion battery can achieve energy density ≥ 160Wh/kg, and cycle life ≥ 6000 times, leading the industry reform.
