- bargle0 6y agoPeople are working on batteries that don't have that problem [1]. [1]: https://www.jhuapl.edu/PressRelease/191014 https://www.jhuapl.edu/PressRelease/191014
- paulmd 6y agoLiFePO4 chemistry is also dramatically safer and is available today. Downside is it's less energy capacity, but for wearable applications it's a lot safer. https://www.batteryspace.com/LiFePO4/LiFeMnPO4-Batteries.aspx https://www.batteryspace.com/LiFePO4/LiFeMnPO4-Batteries.asp... https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery#Safety https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery...
- musingsole 6y agoI got curious about that battery too and found the below datasheet. I don't know what tricks they're pulling to be "ballistic/penetration safe", but I really like the idea of a flexible, wearable battery. I hadn't realized products like it already existed. https://inventuspower.com/wp-content/uploads/2017/10/Inventus-Power_CWB-150_Data-Sheet.pdf https://inventuspower.com/wp-content/uploads/2017/10/Inventu...
- emilecantin 6y agoSoldiers routinely carry things that are designed to explode; getting a round into a wearable battery sounds dangerous, but still less than getting a round into one of your grenades. If it's designed to be worn under some body armor, it shouldn't be too much of an issue.
- bargle0 6y agoGrenades are designed to explode only after the pin is pulled. That's a little different than getting a nick in your battery and suddenly looking like a LiveLeak vape fail video writ large. That being said, there's plenty of work being done on batteries that aren't also incendiary devices waiting for their moment to shine.
- emilecantin 6y agoYou're probably right, I think I took a bad example with the grenades. My point was that your risk tolerance is very different when your job description literally involves getting shot at.
- GaryNumanVevo 6y agoI was more referring to the pinch points between plates and general wear. I.e. you trip and fall onto your side and it punches through
- m-p-3 6y agoCurrent batteries can be dangerous if punctured, that's true. Maybe we'll see those replaced by solid-state batteries once we figure out how to scale the manufacturing process and bring the cost down.
