JAC Group''s Yiwei, a new EV brand in China backed by Volkswagen, debuted the first sodium-ion battery-powered electric car. The new JAC Yiwei EV rolled off the assembly line Wednesday.
Yiwei is a new EV maker under the JAC Group. It was established earlier this year. Volkswagen owns 50% of JAC''s parent company; the other 50% is state-owned.
Volkswagen invested 1 billion euros for a 50% stake in JAC Group in 2021. The German automaker also took full control of management of its existing EV joint venture with a 75% stake.
The new EV features sodium-ion cylindrical cells from HiNa Battery. The Beijing-based tech company is affiliated with the Institute of Physics, Chinese Academy of Sciences.
It will use JAC''s UE module tech, a honey-comb battery structure. JAC''s UE is similar to BYD''s Blade battery, which is used in Toyota, Kia, and Ford EVs. It can also be compared to CATL''s CTP (cell-to-pack) technology.
Deliveries of the new sodium battery-powered Yiwei electric vehicle are expected to begin next month.
JAC introduced the Yiwei 3, the first EV powered by a sodium-ion battery, at the Shanghai Auto Show in February. However, the model launched with an LFP battery, with JAC promising a sodium-ion version was coming.
The automaker also revealed the sodium-ion-battery-powered Sehol E10X, featuring 25 kWh of capacity and 120 Wh/kg of energy density. With 3C to 4C charging, the electric hatchback could recharge from 10% to 80% in 20 minutes.
Volkswagen transferred the Sehol brand to JAC in 2021. Earlier this year, JAC said all vehicles would wear either a JAC or Yiwei badge.
I have high hopes for the new Na-ion battery types to make cheap but good quality cells available for average people once their mass production starts in earnest.
Maybe Na-Ion will bring about a breakthrough and affordable cells really become available.
Although sodium-ion batteries have a lower energy density than lithium-ion ones, they do offer several advantages. According to JAC, they have better low-temperature performance, faster charging speeds, longer lifespans, and increased durability over time.
Perhaps most importantly, the batteries use cheaper raw materials, which can enable lower EV prices.
"Sodium-ion batteries will become an important battery type, complementary to LFP batteries, and a low-cost solution that promotes the popularization of mass electric vehicles to masses," said the chairman of Yiwei Tech, Xia Shunli.

The first electric cars with sodium-ion batteries have gone into production in China. The two small electric car models are being manufactured by Yiwei and JMEV.
In December 2023, a momentous ceremony held at JMEV’s EV plant in Nanchang, Jiangxi Province, witnessed the world’s first electric vehicle (EV) powered by Farasis Energy’s sodium-ion batteries rolling off the production line. This groundbreaking development marks a new era in battery technology, as the JMEV EV3 (Youth Edition) establishes itself as the world’s first A00-class EV to deploy these innovative batteries, offering a substantial range of 251km.
Farasis Energy’s sodium-ion EV battery is truly a marvel in EV battery technology, striking the perfect balance between energy density, safety, low-temperature performance, and life cycle. This battery utilizes a unique combination of layered oxides and hard carbon, yielding an impressive energy density of 140 to 160Wh/kg. The safety standards of these batteries are exceptional, having undergone rigorous testing and demonstrating resilience against pinprick, overcharging, over-discharging, extrusion, and soaking events. Meeting the no thermal runaway (NO TP) standard, this battery pack assures users of its safety.
The low-temperature performance of Farasis Energy’s sodium-ion EV battery is noteworthy. It maintains over 91% discharge capacity retention even at -20°C (-4°F). This outstanding performance ensures that EVs perform optimally even in adverse weather conditions.
Farasis Energy is preparing for an ambitious leap in EV battery technology as it sets sights on releasing its second-generation sodium-ion batteries in 2024. With an anticipated energy density of 160-180Wh/kg and plans to increase this to 180-200Wh/kg by 2026, these batteries are expected to cater to a broader spectrum of applications. Farasis Energy is building partnerships across numerous sectors, such as A00-class micro-electric vehicles, electric two-wheelers, battery-swapping services, and Energy Storage Systems (ESS).
The strategic partnerships foster ongoing success in attracting domestic and international customers. The sodium-ion batteries’ superior performance in low-temperature conditions effectively tackles the range of challenges faced by electric vehicles in frostier climates. Coupled with their safety and affordability, these characteristics ensure a wide variety of use cases while heightening user experience. The innovative sodium-ion batteries are poised to supplement lithium battery systems in several cost-sensitive and safety-critical areas, encompassing residential, industrial, and commercial energy storage.

You can have it. I love my electric lawn mower. It''s so quiet I can easily listen to head phones without needing to blast my eardrums out and doesn''t vibrate my hands so much that they are numb when I get done. The batteries last long enough to do my yard and they are compatible with my weed eater, blower, edger, AND my electric snow blower. I don''t need to store or buy gas or oil. I have multiple batteries that I can exchange while charging. But they only take 60mins at most to change so it''s really not an issue. I will concede that it''s not as powerful as a gas powered but close enough that it doesn''t matter.
