SvoltEnergy recently announced it developed a new 20Ah-class sulfide all-solid-state prototype battery cell for electric vehicles. The 350-400Wh/kg cells underwent successful pinprick and 200°C hot box testing. After mass production, these cells could provide electric vehicles with a range of over 1,000 km on a single charge.

SvoltEnergy says the industry finds it extremely difficult to develop this sulfide technology. Now, the company can prepare solid-state electrolyte films and assemble all-solid-state soft pack cells. It also possesses new equipment development capabilities and kilogram-scale synthesis of solid-state electrolyte materials. So far, SvoltEnergy has submitted 109 sulfide solid-state battery patents.

Compared to lithium batteries, solid-state batteries have improved energy density, charging rates, safety, cycle life, and cell thermal management. They have been classified as the next-gen advanced battery technology.

During the NIO Day 2020 event on January 9, 2021, NIO mentioned solid-state batters when unveiling its NIO ET7, the company’s flagship sedan. It claimed the vehicle expects to feature a 150nkW/h battery, allowing it to reach an NEDC range of 1,000 km. On March 27, Beijing WeLion New Energy Technology verified it became NIO’s solid-state battery supplier.

WeLion has also partnered up with NIO to launch a 1,000 km range hybrid solid-liquid electrolyte battery based on the ET7 model. The 150 kWh and 360 Wh/kg battery pack should start mass production by this year’s end or the first half of next year.

Additionally, Goition High-tech expects to start mass producing its ternary lithium semi-solid-state battery with a 360 Wh/kg energy density sometime this year. Last month, CATL unveiled its CTP (cell to pack) 3.0 Qilin Battery. This 255 Wh/kg energy density battery can also allow vehicles to reach a range of 1,000 km. The company expects to start mass producing these batteries in 2023.
