The world’s first commercial sodium-ion battery production line went live on November 29, a state-owned power firm (CTG) reported on Thursday. The first product from the world’s first GWh-class sodium-ion battery production plant rolled off the line in Fuyang, Anhui province. The two affiliates of CTG as well as the Fuyang municipal government jointly supported this production line of sodium-ion batteries by Hina Battery.

Chinese power battery producers and manufacturers like CATL, CTG, etc are putting a lot of effort into developing sodium-ion batteries.

CTG

According to CTG, the sodium ion battery’s introduction marks a significant milestone in the industrialization of sodium-ion batteries and the industry’s ability to create GWh-class sodium-ion batteries on a big scale.

The sodium ion battery was unveiled and made available by Hina Battery in 2017, the same year it was founded and established. According to a press statement from the energy giant, Hina Battery has brought a sodium-ion battery production line that is backed by the two associates of CTG as well as the Fuyang local administration. They have joined forces to construct the first sodium-ion battery mass production line in history.

The line will be constructed in two phases, the first of which will have a capacity of 1 GWh and the second will have a total capacity of 5 GWh.

According to the website of Hina Battery, its current sodium-ion battery has a cycle life of 4,500 cycles and an energy density of 145 Wh/kg.

CATL

With the announcement that the energy density of the single cell of its first generation sodium ion battery had reached 160 Wh/kg, the greatest of its kind ever, CATL debuted the sodium ion battery.

According to a statement made by CATL last year, the energy density of its next generation sodium-ion batteries will surpass 200 Wh/kg. The company also stated that it has begun the industrialization of sodium ion batteries and intends to establish a fundamental industrial chain by the year 2023.

Benefits

The sodium ion battery asserts to be safer, cleaner, and more affordable in addition to charging more quickly and performing better in adverse weather conditions.

In addition to being inexpensive, sodium batteries are nonexplosive and safer for the environment than lithium batteries. Sodium batteries do not easily heat up.

Sodium batteries operate on a similar concept to lithium-ion batteries. The ion moves between the anode and cathode in both cases, absorbing or losing electrons along the way. Despite its superior performance, lithium is still a scarce raw material making sodium a better alternative.

Conclusion

Due to sodium’s inexpensive cost and high abundance, compared to lithium, the concept has long been promoted for use in commercial batteries, and its manufacturing demonstrates that this potential is finally being realised.

The battery industry is making a significant push for lithium alternatives. The obvious choice seems to be sodium because it is less expensive and easier to mine and process than other elements. Sodium-ion batteries are viewed as a practical solution for widespread deployment as technology advances at a rapid rate.

In the upcoming years, it is anticipated that the sodium ion battery industry would expand quickly thanks to increased expenditures and focused research and development initiatives to smooth the transition from pilot plant-scale production to full commercialization.
