On September 20, Bai Na New Energy released two sodium ion battery cathode materials, namely Bai Na 1 (P2 type high stability high voltage cathode material) and Bai Na 2 (O3 type high stability high capacity cathode material), as well as the "Tianxi 1" sodium ion battery cell based on the material development.

Bai Na 1 cathode material belongs to P2 type high stability high voltage cathode material, and Bai Na 2 cathode material belongs to O3 type high capacity cathode material, which have applied for relevant patents.

The Tianxi 1 sodium ion battery cell has a specification of BN32700-5Ah, and the charging and discharging voltage range is 2.0-4.4 V, with excellent high rate discharge capacity, low temperature performance and cycle stability. This sodium ion battery cell can be used for car starter power supply, two-wheeled vehicles, low-speed vehicles, dry line logistics vehicles, etc., and no fire has been caused through drop, heavy impact and needle puncture tests.
