Kakauolelo-nui o ka National Electric Power Storage Technical Committee a me ka loea ʻenehana pae hoʻolālā o ka Southern Power Grid.
ʻOiai ʻo ka hana a Kina i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, ka hoʻomaʻamaʻa ʻana, ka hoʻolaha ʻana i ka mākeke a me ka hoʻohana ʻana i nā huahana pākaukau sodium-ion ke holo piha nei, ʻaʻohe kumu mua o ka honua no ka hoʻohana ʻana i ka ʻenehana ʻenehana sodium-ion i nā kikowaena mana mālama nui. .
I Nowemapa 2022, Guangxi Power Grid Company, i hui pū me ka South Grid Energy Storage Company, ka Institute of Physics of the Chinese Academy of Science, Zhongkehai Sodium Technology Co., Ltd. noiʻi nui a me ka papahana papahana papahana sub-kumuhana "100 megawatt-hour sodium-ion pākaukau waihona ikehu ʻenehana hoʻohui ʻenehana a me ka hōʻike noiʻi" noiʻi E hoʻopaʻa i ka hana.

ʻO ke kelepona paʻa kiʻekiʻe ka ʻāpana kumu o ka ʻōnaehana mālama ikehu pālolo sodium-ion. Ma hope o hoʻokahi makahiki a me ka hapa o ka noiʻi ʻana, ua hoʻomohala ka hui papahana i ka honua holoʻokoʻa, ākea ākea ākea, palekana kiʻekiʻe 210Ah sodium-ion ikehu waihona.
