The EV maker did not mention the supplier of the battery at the time. Nio unveiled a 150-kWh semi-solid-state battery when it launched its flagship sedan, the Nio ET7, on Januat the Nio Day 2020 event. Li acknowledged that the company may not be able to erode the market share of lithium-ion battery giants like CATL, and that WeLion's market share could be less than 1 percent by 2025, according to the report. WeLion is building four more battery production facilities in China to increase its annual capacity to 30 GWh by 2025 from the current 6 GWh, the report said, adding that in addition to electric vehicles (EVs), the batteries could also be used in energy storage systems and drones. CATL, the world’s largest EV batter producer, has challenged the viability of Toyota’s plan.WeLion's solid-state battery technology has attracted interest from a number of automakers, including Volkswagen, Ford, Mercedes-Benz, Geely Automobile Holdings and Xiaomi, the report quoted Li as saying. Toyota said that it expects to produce its first solid-state battery for consumer applications in 2027. Achieving cost parity with lithium-ion batteries and making solid-state batteries economically viable for mass-market EVs is a significant challenge. Scaling up production while maintaining quality and cost-effectiveness is a significant challenge. Solid-state batteries require precise and complex manufacturing processes, which currently make them more expensive to produce compared to lithium-ion batteries. There are several challenges, however, associated with the development and widespread adoption of solid-state EV batteries. Solid-state EV batteries offer numerous advantages over traditional lithium-ion batteries, such as higher energy density, improved safety, and faster charging capabilities. WeLion achieved a significant milestone last November when their first solid-state cell was produced at their Huzhou battery production facility. Initially, Nio owners will have the opportunity to experience the 150-kWh battery pack through a rental program this summer, with an option to purchase the battery pack in the future. Qin Lihong, Nio’s co-founder and president, mentioned at an event in Changzhou, Jiangsu province on February 11, that the cost of the 150-kWh pack is roughly equivalent to that of an ET5 sedan, which currently starts at 298,000 Yuan ($41,090). The 150-kWh battery pack, however, is currently quite expensive due to its utilization of the latest battery technology. According to Li, the Nio ES6 equipped with the 150-kWh pack can achieve a range of 930 km (577 miles). William Li, founder, chairman, and CEO of Nio, announced on May 24, during the launch of the new ES6, that the 150-kWh semi-solid-state battery pack would be available in July. Regulatory filings indicated that with the new WeLion’s batteries, Nio vehicles would only have a 20 kg weight increase. The delivery schedule for the battery faced multiple delays, with Nio filing for the use of the pack in their models in May. Nio had unveiled the 150-kWh semi-solid-state battery during the Nio Day 2020 event on January 9, 2021, when they introduced their flagship sedan, Nio ET7. WeLion also announced the official opening of its R&D center for the Yangtze River Delta during the delivery ceremony. He emphasized that this delivery marks just the beginning of the growth trajectory for WeLion and Nio, expressing hope that it will lead to technological advancements across the industry. Zeng Shizhe, Nio’s vice president of battery systems, stated that the delivery of the Li-ion battery cells is great news for Nio owners, as they will continue to benefit from the battery upgrade. WeLion’s chairman, Yu Huigen, referred to the delivery of the Li-ion battery cells as a significant milestone for the industry, achieved through the collaborative efforts of Nio and WeLion over the past two years. The Li-ion cells with a capacity of 360 Wh/kg were delivered to Nio’s manufacturing facility in Huzhou, Zhejiang province. Chinese electric vehicle (EV) auto giant, Nio, is gearing up to deliver high-energy-density cells to its customers this month as its semi-solid-state battery supplier, Beijing WeLion New Energy Technology, has started supplying the batteries to Nio.
