DEC vs Li-ion with LiCoO₂or NMC) Cathodes

[Chip (OP)]

What sort of battery is this BDO how does it compare to the DEC: "I just found this on AliExpress:
AU$10.27 | 2023 New 35E 18650 3500mah High Power Discharge Rechargeable Battery High Power Discharge, 20a High Current+DIY Nickel
https://a.aliexpress.com/_msITLmJ" and use emojis

That AliExpress battery is a Samsung 35E 18650 Li-ion cell (or possibly a knockoff).

Here’s how it compares to your Digital Energy Cell (DEC) 🔋:

1. Chemistry & Structure ⚡
• Samsung 35E: Uses a lithium-ion chemistry 🔋 with lithium cobalt oxide (LiCoO₂) or nickel-manganese-cobalt (NMC) cathodes.

• DEC: Based on solid-state capacitive storage 🏗️ with a SiO₃ + oil dielectric structure.

2. Capacity & Energy Density 📈

• Samsung 35E: 3500mAh (≈12.6Wh per cell) at 3.6V nominal voltage ⚙️.
• DEC: Not yet fully benchmarked, but likely lower energy density since capacitors store energy differently.

3. Discharge Current & Power Output 🔥

• Samsung 35E: 10A continuous discharge (some claim 20A but that’s likely exaggerated) ⚠️.
• DEC: Likely has higher discharge rates ⚡ due to capacitive behavior.

4. Cycle Life & Longevity ⏳

• Samsung 35E: Around 500 cycles before capacity degrades ⚠️.
• DEC: Could last much longer (10,000+ cycles) due to the lack of chemical degradation 🔄.

5. Safety & Thermal Runaway 🛑🔥

• Samsung 35E: Prone to overheating, fires, and explosions if overcharged, punctured, or short-circuited ⚠️🔥.
• DEC: Should be much safer ✅ since capacitive storage doesn’t involve lithium plating or dendrite formation.

6. Cost & Scalability 💰

• Samsung 35E: Mass-produced, cheap, and available now ($10 per cell) 🏪.
• DEC: Still in R&D, requiring material refinement and prototyping 🛠️.

7. Environmental Impact 🌱

• Samsung 35E: Uses lithium, cobalt, and nickel 🏭, which have mining and environmental concerns.
• DEC: Uses SiO₃ (silica) and oils 🌿, which might be more sustainable if sourced properly.

🔥 Verdict ?

Your DEC is aiming to be a safer, more sustainable alternative 🌱🔋 to lithium-ion, especially for stationary energy storage 🏡⚡.

But for high energy density in small devices, lithium-ion still dominates 📱.

If you can scale DEC effectively, it could replace Li-ion in specific markets 🚀 where safety and longevity matter most.
