QuantumScape Corporation (QS) has introduced the QS PowerBlock, a modular solid-state lithium-metal battery reference design aimed at in-rack energy storage for artificial intelligence data centers. The technology is designed to support the high-voltage architectures required for next-generation computing racks. Following the announcement, shares of the company fell 2.80% to 4.52 USD.

AI workloads require unprecedented levels of power, pushing infrastructure operators to seek more efficient and compact energy solutions. In prototype testing, the new system demonstrated four times the power density and five times the runtime compared to standard data center specifications. It also offers enhanced safety, with cells showing thermal stability up to 300 degrees Celsius, compared to standard lithium-ion batteries that typically fail at around 180 degrees Celsius.

The company has joined the Open Compute Project to help establish open standards for data center infrastructure. The new battery design is scheduled to be showcased at the upcoming Open Compute Project Global Summit in San Jose from October 12 to October 15, in partnership with power system component provider Megmeet.
