Battery maker: Solid-state batteries to drastically fall in price by 2026

Chinese battery maker Sunwoda shared its views on the evolution of solid-state batteries. A whole bunch of companies are developing their solid-state solutions and Sunwoda is no exception, but the latest update from the company is important as it relates to the broader industry trends.

According to Sunwoda, the price of solid-state batteries will match the current price of semi-solid-state batteries, which will be around $0.275 per Wh. While that's expensive by today's standards, the price to performance ratio would still be excellent and would easily make them a preferred choice for a number of vehicle categories.

Nio's 150 kWh semi-solid-state battery for the ET7 is said to cost as much as the entire ET5 car, complete with a 75 kWh conventional battery.

Sunwoda, however, believes it will start delivering solid-state batteries that will make far greater economical sense in 2026. These batteries would have an energy density of more than 400 Wh/kg, which is more than Nio's 150 kWh pack, which offers 360 Wh/kg.

Moreover, Sunwoda already has lab prototypes with 500 Wh/kg energy density, using lithium metal in the negative electrode. We can then see 700 Wh/kg solid-state batteries in 2027, the maker predicts.

The battery manufacturer didn't disclose any further details about its potential breakthrough, but it's building a dedicated solid-state battery production line capable of delivering 1 GWh worth of batteries per year.
