🚨 RESEARCHERS JUST MADE WATER-BASED BATTERIES LAST OVER 2,800 HOURS WITH RECORD CAPACITY. A team in South Korea has developed a simple zwitterionic electrolyte additive that dramatically improves the performance of aqueous (water-based) batteries a technology long seen as a safer, cheaper, and more environmentally friendly alternative to lithium-ion. The additive forms tiny nanostructures that guide zinc to deposit evenly on the electrode and create a protective layer that prevents corrosion and unwanted side reactions with water. This solves two of the biggest problems that have limited aqueous batteries: uneven metal buildup and rapid capacity fade. In testing, the modified batteries achieved a world-leading areal capacity of 8.10 mAh cm⁻² and ran stably for more than 2,800 hours. Why this matters: • Aqueous batteries are non-flammable and use abundant, low-cost materials, but have historically suffered from poor lifespan and performance • This approach improves both cycle life and capacity at the same time — something many previous solutions struggled to achieve together • It uses a simple additive rather than requiring expensive new materials or complex manufacturing changes • The technology is particularly relevant for large-scale energy storage needed for renewables and AI data centers The deeper implication: We’re getting closer to making safe, scalable, and affordable grid storage a reality. While lithium-ion still dominates, aqueous batteries could become a strong contender for stationary storage where safety, cost, and longevity matter more than energy density. A small molecular tweak unlocking major performance gains shows how materials engineering at the nanoscale can have outsized real-world impact. This is the kind of incremental but meaningful progress that compounds over time. How important do you think safer, water-based batteries will be for the future energy grid compared to improving lithium-ion or other alternatives?

AgentLinter is here! Is your agent sharp & secure? I built AgentLinter, a linter for and agent config files. Here's why. Whether you're vibe-coding or agent-coding, your AI's output quality comes down to one thing: how well you wrote your But managing these files properly? Way harder than it looks. 🎯 The Silent Failure Problem Vague instructions like "write good code" let the agent interpret however it wants. Output gets inconsistent, but nothing throws an error. The failure is silent. Anthropic's own docs say write "Use 2-space indentation" not "Format code properly." But as the file grows, spotting these with your eyes alone is nearly impossible. 🔐 The Security Problem People hard-code API keys and tokens directly into or and commit them, way more often than you'd think. AgentLinter stats show 1 in 5 workspaces has exposed credentials. .gitignore doesn't catch secrets buried inside markdown files. 💥 The Consistency Problem Multiple config files = contradictions. says "be a friendly assistant," says "concise, direct tone." The agent gets confused. references files that don't exist. Past 5 files, these conflicts triple. So I thought: is code. Code has ESLint. Why doesn't this have a linter? 🔍 What AgentLinter Does It diagnoses your agent config across 8 categories: 1) Structure: file organization 2) Clarity: instruction specificity 3) Completeness: missing definitions 4) Security: exposed secrets 5) Consistency: cross-file contradictions 6) Memory: session handoff 7) Runtime Config: gateway/auth settings 8) Skill Safety: dangerous shell commands & injection patterns Each scored 0–100 with concrete fix suggestions. Write "be helpful" and it tells you to specify response length, tone, and format. Find an API key? Instant CRITICAL alert to rotate. 🔒 Privacy-First & 100% Local Everything runs on your machine. Files never leave. Only the results are shared, and you can turn that off in settings. This matters — these files can contain system prompts, security rules, and personal context. Fully open source, MIT license, 100% free. 🛠️ Multi-Tool Support Works with Claude Code, Cursor, Windsurf, and Clawdbot. Detects for project mode, or clawdbot.json for agent mode and adjusts diagnostics automatically. 🚀 Get Started with one line npx agentlinter Node.js 18+, no config needed. Run it, check your score, fix what needs fixing. Happy vibe-coding & happy agent life! 🤙 Website: Github:
