Nio's (NYSE: NIO) semi-solid-state battery supplier began delivering high-energy-density cells to it as the Chinese electric vehicle (EV) maker is set to begin delivering them to vehicle owners later this month.
Beijing WeLion New Energy Technology began delivering 360 Wh/kg Li-ion cells to Nio on June 30, holding a delivery ceremony in Huzhou, Zhejiang province, where its manufacturing facility is located.
WeLion executive vice president Xiang Jin formally delivered the battery cells to Nio senior vice president Zeng Shuxiang and submitted a warranty commitment, and the two sides signed an annual order, a press release from the battery maker said today, without disclosing the amount of the order.
The delivery of the battery cells to Nio is an industry-wide milestone event, the result of more than two years of joint team efforts between Nio and WeLion, WeLion chairman Yu Huigen said at the delivery ceremony.
Yu also expressed his gratitude to the Huzhou city government for the smooth start-up of WeLion's phase I plant in the city.
The delivery of this Li-ion battery cell is good news for all Nio owners, who can continue to enjoy the benifits of the battery upgrade, said Nio battery systems vice president Zeng Shizhe.
"Today's delivery is just one small step in the growth of WeLion and Nio together, and hopefully this small step will lead to a big leap in technology for the whole industry," he said.
WeLion also announced at the delivery ceremony that it has officially opened the company's R&D center for Yangtze River Delta in Huzhou.
WeLion is headquartered in Beijing and has four production sites in Fangshan, Beijing; Liyang, Jiangsu; Huzhou, Zhejiang; and Zibo, Shandong, according to its press release.
Of those, the Huzhou site is WeLion's automotive power battery production base, it said, without disclosing details of the other production sites.
Nio unveiled the 150-kWh semi-solid-state battery when it launched its flagship sedan, the Nio ET7, at the Nio Day 2020 event on January 9, 2021.
After that, the battery's delivery schedule was delayed several times, and Nio filed for the use of the pack in its models in early May of this year.
With WeLion's batteries, Nio's vehicles will weigh just 20 kg more than before, according to regulatory filings at the time.
On May 24, at the launch of the new ES6, William Li, founder, chairman and CEO of Nio, announced that the 150-kWh semi-solid-state battery pack will be available in July.
The new Nio ES6 can get a range of 930 km when equipped with the 150-kWh pack, he said at the time.
It is worth noting that this battery pack is currently very costly because it uses the latest technology.
The 150-kWh pack costs about the same as an ET5 sedan, Nio co-founder and president Qin Lihong said at a face-to-face event in Changzhou, Jiangsu province on February 11. The ET5 currently starts at 298,000 yuan ($41,090).
Nio owners will be able to start experiencing the 150-kWh battery pack during the summer, which will initially be available for rent only, with a buyout option available in the future, Qin said at the time.
On November 22, 2022, WeLion saw the first solid-state cell roll off the line at its battery production facility in Huzhou.
WeLion began construction of its Huzhou battery site in 2021 and completed construction of the plant and production line after a year, said Tian Qiyou, general manager of the company's Huzhou branch at the time.

China's largest carmaker SAIC Group expects to see its first model with solid-state battery roll off the assembly line in two years, as more local carmakers target the new battery technology for a longer range.
SAIC is ramping up its research and development work on solid-state battery cells and is making every effort to promote the large-scale application of solid-state batteries, the company said in a recent investor survey, according to a May 22 report by local media Jiemian.
SAIC's first mass-produced model with the solid-state battery will roll off the production line in 2025, it said, adding that it will allow users to enjoy a safe car experience while providing them with higher energy density power battery cells.
The report did not provide any further details. SAIC has not disclosed the investor activity.
On May 19, Ganfeng Lithium -- the world's largest lithium producer by market capitalization -- said in the minutes of an investor meeting that it had begun mass production of its first-generation solid-state battery.
Ganfeng's first-generation solid-state battery can reach an energy density of 260 Wh/kg, and its production line is designed to have an annual capacity of 4 GWh, according to the minutes.
Back at SAIC, its solid-state battery appears to have been developed with local startup QingTao Energy Development, similar to what NIO did with Beijing WeLion New Energy Technology.
On July 6, 2022, SAIC announced that it had set up a joint lab with QingTao to develop solid-state batteries.
The two will focus on the mass production of solid-state batteries with a range of more than 1,000 kilometers, 4C fast-charging technology and the development of high-safety, long-life solid-state batteries, according to a press release at the time.
C refers to the battery's charging multiplier, and 4C means that the battery could theoretically be fully charged in a quarter of an hour.
The lab will also conduct high-efficiency solid-state battery integration technology development to push solid-state battery technology to accelerate mass production, SAIC previously said.
NIO unveiled a 150-kWh semi-solid-state battery when it launched its flagship sedan, the NIO ET7, at the NIO Day 2020 event on January 9, 2021, thus bringing the new battery technology to wider attention.
Earlier this month, NIO filed for the addition of WeLion as a battery cell supplier in three models, signaling that its 150-kWh semi-solid-state battery pack is not far from being available.

China's Ganfeng Lithium -- the world's largest lithium producer by market capitalization -- said it has begun mass production of its first-generation solid-state battery, after announcing the new technology in late 2021.
Ganfeng revealed the progress in a May 19 investor conference meeting minutes, saying its first-generation solid-state batteries can reach an energy density of 260 Wh/kg and that the production line is designed to have an annual capacity of 4 GWh.
Production of the solid-state battery is currently undergoing capacity creep, with application scenarios including power batteries and energy storage, according to the minutes.
Ganfeng's second-generation hybrid solid-state lithium battery uses lithium metal as the anode and can reach an energy density of 400 Wh/kg, the company said.
The safety performance of the second-generation solid-state battery meets automotive requirements, and the cycling performance of the sample battery has met the requirements of car companies, Ganfeng said.
Ganfeng unveiled its first-generation solid-state battery, a hybrid solid-state and liquid lithium-ion battery, on December 10, 2021.
The battery has an oxide electrolyte and uses graphite for the anode. It has a diaphragm, but unlike conventional diaphragms, it uses a solid electrolyte diaphragm.
Ganfeng did not announce the energy density of the first-generation solid-state battery at the time, but said the second-generation solid-state battery had an energy density of more than 360 Wh/kg.
The company's latest announcement means that it has made new progress in the development of the second-generation solid-state battery over the past year and a half, allowing for a further increase in energy density.
Current mainstream lithium-ion battery cells have an energy density of just over 200 Wh/kg, and NIO's (NYSE: NIO) 150 kWh semi-solid-state battery, expected to be available within months, is 360 Wh/kg.
On April 19, CATL unveiled its new battery technology, Condensed Battery, which claims an energy density of up to 500 Wh/kg for a single cell.
The Condensed Battery will be available for use in electric vehicles and will have mass production capability within this year, said Wu Kai, CATL's chief scientist at the time.

NIO's (NYSE: NIO) models are finally close to being able to use higher-capacity semi-solid-state batteries, according to the latest regulatory filing.
China's Ministry of Industry and Information Technology on May 9 released a catalog of the latest batch of models that will soon be allowed to be sold in China, as well as hundreds of vehicle companies' filings for vehicle specification changes for public comment.
The public can submit feedback between May 10 and May 16. Entry into these catalogs is a key regulatory process by which a model can be allowed to be sold or approved for specification changes in China.
NIO did not file for new models but did file for three models with an expansion of the specification information to add semi-solid-state batteries to the battery information.
The three models include two SUVs and one sedan, model numbers HFC6502ECSEV9-W, HFC6502ECSEV5-W, and HFC7002CSEV1-W, respectively.
The specification changes for all three models add the use of battery cells from Huzhou WeLion Technology Co Ltd. The assembly based on this cell is produced by a subsidiary of NIO in Nanjing.
The information does not mention solid-state batteries, but Huzhou WeLion is a wholly owned subsidiary of NIO's semi-solid-state battery supplier, Beijing WeLion New Energy Technology.
NIO announced the 150-kWh semi-solid-state battery when it unveiled its flagship sedan, the NIO ET7, at the NIO Day 2020 event on January 9, 2021, although deliveries have not yet begun.
On November 22, 2022, WeLion saw the first solid-state battery cell roll off the assembly line at its battery production facility in Huzhou, Zhejiang province, eastern China.
WeLion celebrated the occasion with a ceremony attended by NIO senior vice president Zeng Shuxiang and officials from Huzhou city, according to the company's press release at the time. Zeng is the CEO of XPT, NIO's electric drive division, and a director of WeLion.
WeLion started construction of its battery base in Huzhou in 2021 and completed construction of the plant and production line after a year, said Tian Qiyou, general manager of the company's Huzhou branch at the time.
The latest specification change filing shows that with WeLion's batteries, NIO's vehicles will weigh just 20 kg more than before.
NIO has not updated information about the battery in recent months. Its co-founder and president, Qin Lihong, said at a face-to-face event in Changzhou, Jiangsu province, on February 11 that NIO owners will be able to start experiencing the 150-kWh pack during this summer.
The pack will initially be available for rent only, with a buyout option available in the future, Qin said at the time.
