Chinese battery manufacturer SVOLT has begun series production of semi-solid-state batteries. The first batch of battery packs with 100 kWh capacity has rolled off the production line in Changzhou, Jiangsu Province. These are said to support fast charging with a charging rate of 6C.
SVOLT Chairman Yang Hongxin announced the start of series production this week in a video published on Weibo. According to the announcement, SVOLT has produced the first batch of its so-called ‘Dragon Armor’ battery using series production methods. Hongxin also stated that the 100-kWh battery pack is being considered by ‘multiple’ customers and that details about the vehicles in which it will be used will follow soon.
For context: the ‘Dragon Armor’ battery is an energy storage system based on cells with a semi-solid electrolyte. Such semi-solid-state batteries represent a battery type positioned between traditional lithium-ion batteries with liquid electrolytes and solid-state batteries with fully solid electrolytes. They use a combination of liquid and solid materials in the electrolyte, often referred to as a solid-liquid hybrid. Battery manufacturers hope this technology can deliver improved safety, higher energy density, and a longer lifespan compared to conventional lithium-ion batteries.
Regarding the new SVOLT battery, the company reports that it features liquid cooling on both the top and bottom and supports up to 900 volts. The manufacturer specifies a charging rate of 6C, which, according to the datasheet, allows a range of around 500 kilometres to be recharged in twelve minutes. The lifespan is stated to exceed 3,000 cycles.
