  • Apr 21 — [News] CATL Super Tech Day, Beijing. Six product lines: Shenxing Gen-3 LFP (10→98% in 6m27s — fastest commercial LFP charge to date), Qilin Gen-3 Condensed Battery, NaXin sodium-ion (passenger + grid), Xiaoyao Gen-2 super extended-range hybrid, Super Swap-Integrated network. Direct response to BYD's gen-2 Blade. (CATL Super Tech Day)
  • Apr 21 — [News] CATL announces 932-mile (1,500 km) range battery pack — among the highest disclosed by any tier-1 cell maker. Likely high-nickel NCM on Qilin CTP architecture. (932-mile pack)

May

  • May 13 — [Paper] Two companion arXiv papers formalize "connect-and-manage" AI-datacenter grid interconnection — gigawatt-scale data centers connect without prior transmission upgrades in exchange for accepting real-time curtailment. Simulation on the IEEE 39-bus system (Australian market data) shows a coordinated request/acceptance protocol cuts curtailment from 9.1% to 2.8% while preserving 98.1% of frontier-training workload; on-site battery storage buffers checkpoint-constrained training continuity against the resulting power-import limits. (Grid Integration, Battery-Assisted Operation)
  • May 31 — [Paper] FERC-filing analysis identifies transmission/interconnection — not generation — as the near-term binding constraint on AI data center growth: regional capacity gaps of 50-150+ GW by 2030-2035, with interconnection queues extending 5-10+ years in the most congested regions. (Power Grid Infrastructure for AI Data Centers)

June

  • Jun 9 — [News] GM commits to US-developed sodium-ion grid-scale storage at its GM Empower event (San Francisco), partnering with Peak Energy (GM Ventures-backed). Cell prototyping starts 2026 at GM's Wallace Battery Cell Innovation Center. First major Western incumbent in stationary sodium — abundant materials, passive cooling, royalty-free domestic manufacturing as a geopolitical hedge, pulled by AI-data-center demand. (GM/Peak Energy Sodium-Ion)
  • Jun 18 — [Technical Report] Honda signs a multi-year joint solid-state development deal with QuantumScape — covering EVs, motorcycles, power equipment, and energy storage. Validates QuantumScape's capital-light process-licensing model; QS shares rose ~12%. (QuantumScape Eagle Line)
