Until recently, SpaceX has relied primarily on self-produced batteries for its spacecraft. However, as the demand for consistent and advanced power systems has grown, the need for specialized external suppliers became evident. According to industry insiders that spoke with the Korea Economic Daily (KED), LG Energy Solution will provide batteries for both primary and backup power in the Starship rocket.

Temperatures in Starship’s engines can reach up to 3,000 degrees Celsius, requiring batteries that can withstand intense heat without losing performance.

I'm no rocket scientist but I'd put the batteries somewhere other than in the engines.

Still, they presumably have to operate in vacuum so thermals will be a challenge. The vibration at launch must also be pretty gnarly.

Nah, the main combustion chamber is obviously the optimal battery location.
