After the Chinese brand Sihao, it’s up to Renault to start producing sodium batteries, without lithium. To do this, the French firm is working hand in hand with its Chinese partner Farasis Energy to equip a first electric car, the new EV3.

After that of the prices declared by Tesla, there is another war that many manufacturers oppose: that of batteries. In fact, while many specialists are concerned about a possible lithium shortage in the future, brands are now working on developing new alternatives. Among them, the sodium battery, which is of great interest to the different players in the automotive industry.

Renault gets involved

A few days ago, the Chinese brand Sihao, owned by the JAC (Anhui Jianghuai Automobile Group Corp) group of which Volkswagen is a part, announced the arrival of a new version of its Flower Fairy city car equipped with a sodium battery. a big step forward thanks to supplier Hina Batterywhile the car turns the first in the world to be equipped with this technology. But that shouldn’t last long.

In fact, now it is the turn of another Chinese company, Jiangling Motor Electric Vehicle (JMEV) to announce that it is also ready to equip one of its cars with a lithium-free battery, as the site explains Yicai Global. If you do not know this brand, it is quite normal, because it is only present in China. And you probably didn’t know it, but it belongs to the Renault group.

Whereby the French manufacturer is therefore one of the first to offer this type of technology. If it’s not already present in a production vehicle, it shouldn’t take too long. In fact, and as the site explains electric, the supplier Farasis Energy has announced that it has already converted certain production lines at its plant in Ganzhou, China, to produce these accumulators. Thus, the first will be implanted in the compact EV3.

Totally unknown in Europe, the electric car sold by the Chinese company JMEV should therefore begin series production with these new batteries. At the end of june. Already present in the manufacturer’s catalogue, it is currently offered with an electric motor with a power of 35 kW (47 hp) and a 32 kWh battery. As shown on the brand’s website, it comes with complete equipment, including 360-degree vision and blind spot detection.

a real asset

Last August, Farasis Energy also announced its ambition to build a new factory in Ganzhou as well, which would be capable of producing up to 30 GWh per year. By comparison, the recently commissioned CATL site in Europe plans to produce 14 GWH each year, while Tesla plans 100 GWH at its Gigafactory in Berlin, or even 250 after its expansion.

At the moment, the company has not yet given all the technical details about this new Na-ion battery, but journalists fromautomotive cleaning announce that this shows a capacity of 32 kWh. Thus, the 3.70 meter long urban car will be able to travel up to 302 kilometers on a single charge. This is probably the Chinese CLTC cycle, much more bullish than our WLTP which should give about 256 kilometers.

If nothing has been announced yet, it is quite likely that this technology will be exported to Europe and that it will equip certain models of the Renault group, including the Dacia Spring or the future electric R5.

A battery to reduce the price of electric cars

Above all because it has many advantages, starting with a lower cost due to the absence of lithium, the price of which tends to increase. Thus, it will be possible to offer larger batteries, while the only solution currently planned to reduce the price of cars is to offer smaller packs.

AND stored energy density is less important Than an LFP (Lithium-Iron-Phosphate) battery, this technology better supports rapid, repeated charging. This is consistent with the development of the network of fast charging stations, especially since it is no longer relevant to have a car with a lot of autonomy. Finally, the sodium batteries are also more resistant to colda real asset when you know that it has a negative impact on charging speed and autonomy.
