Solid-state Battery

Following the completion of the financing, WeLion will further accelerate the construction of its production line and increase its R&D investment.

Nio is expected to receive a small batch of 150-kWh semi-solid-state batteries from WeLion in September and start using them in the fourth quarter, according to a previous media report.

Ganfeng's Chongqing-based project will have 10 GWh of battery capacity and 10 GWh of pack capacity when completed.

Nio's semi-solid-state batteries purchased from WeLion are not significantly more expensive than the existing liquid batteries, according to local media.

The battery will give the Nio ES8 a range of 850 kilometers, the ES6 a range of 900 kilometers and the ET7 a range of more than 1,000 kilometers.

The cells have an energy density of 350-400 Wh/kg and has now successfully passed tests including pin prick and 200°C hot box tests, Svolt Energy said.

The all-solid-state battery cells show excellent cycling performance, with 71 percent capacity retention even after 20,000 cycles.

Solid-state batteries with a range of more than 1,000 kilometers, developed by the two companies, will be the first to be installed in a new SAIC-owned model next year.

The semi-solid-state battery has an energy density of 360Wh/kg, much higher than the 210Wh/kg of conventional ternary lithium batteries, according to a Gotion executive.

The partnership will help accelerate the further commercialization of semi-solid-state batteries and solid-state batteries, WeLion said in a statement today.
