GM, Peak Energy partner on sodium-ion grid storage

General Motors has backed sodium-ion startup Peak Energy to co-develop passively cooled battery storage systems purpose-built for grid applications and AI data centers. The technology leverages abundant raw materials to target 20% lower lifetime costs and a 20-year operating life, with prototyping scheduled for 2026.

// ANALYSIS

Automakers backing sodium-ion grid storage highlights a broader recognition that stationary energy needs demand fundamentally different chemistries than electric vehicles.

• Sodium-ion battery tech circumvents lithium and cobalt supply chain bottlenecks by utilizing abundant sodium resources.

• Passive cooling design eliminates complex active liquid cooling, lowering maintenance costs and minimizing fire hazards.

• Deep involvement from GM signals strong automotive manufacturing interest in supplying the rapidly expanding AI data center and utility grid market.

Lower reasoning effort boosts Claude Opus 5 performance

In a video evaluation by Every, testing shows that Anthropic's Claude Opus 5 performs significantly better when configured with medium or low reasoning effort rather than maximum thinking settings. While max reasoning is designed for heavy problem-solving, it frequently causes the model to overthink, over-complicate solutions, and introduce unnecessary errors.
