Chinese language electrical automobile and battery know-how big BYD has flagged plans to constructing a brand new multi-billion greenback battery plant base to fabricate sodium-based batteries for its EVs.
BYD has signed a take care of native firm, Huaihai Holding Group, to fabricate as much as 30 GWh of annual battery manufacturing, in response to cnevpost.
It says BYD’s battery division will construct the Sodium battery plant in Xuzhou, situated within the jap a part of China with an annual value of 10 billion RMB or $A2.15 billion. This would be the largest mission of its sort, though there was little details about the character and efficiency of the sodium-based batteries.
One of many key assumed advantages of sodium primarily based batteries over lithium ion is decrease prices, and a decrease dependence on some minerals which might be both uncommon or have risky markets, or each.
In latest months, nonetheless, the costs of Lithium carbonate have fallen significantly, making Lithium-ion batteries cheaper once more, as Goldman Sachs report.
This has doubtlessly shifted the main target from Sodium battery growth initiatives, however Swedish big NorthVolt has additionally introduced a breakthrough in sodium batteries – no less than for vitality storage – that would circulate via to EVs.
These batteries are prone to find yourself in smaller EVs such because the BYD Seagull which is anticipated to be BYD’s top-selling automobile globally after launching earlier in 2023.
BYD at the moment specialises in its Blade battery know-how which is lithium primarily based. All automobiles it sells in Australia has this battery know-how. Together with that, BYD additionally provides its batteries to Tesla to provide Mannequin Ys in Europe.
Given the size required and the chance to spend money on a Sodium manufacturing base, it permits BYD to have redundancy in case the Lithium carbonate costs rise rapidly within the coming years.
This may assist maintain the price of extra inexpensive EVs low whereas persevering with to develop sodium battery applied sciences. Such batteries are prone to find yourself in smaller EVs such because the BYD Seagull which is anticipated to be BYD’s top-selling automobile globally after launching earlier in 2023.

He’s a mechanical engineer who spent the primary 7 years of his profession constructing transport infrastructure earlier than beginning carloop. He has a ardour for vehicles, significantly EVs and desires to assist cut back transport emissions in Australia. He at the moment drives a purple Tesla Mannequin 3.
