Printable battery paves the way for custom-shape power sources
https://www.electronics-lab.com/printable-battery-paves-way-custom-shape-power-sources/
A new type of batteries called “Printable Solid-State (PRISS) Lithium-Ion Batteries” was designed by a group of researchers from the Ulsan National Institute of Science and Technology (UNIST, South Korea). The new battery is created from consecutive layers of printed composite materials. With a simple stencil printing process followed by ultraviolet cross-linking, a solid-state composite […]

Disconnect circuit for 12 volt lead acid and lithium batteries
https://www.electronics-lab.com/50967-2/
KA7OEI designed a circuit that disconnects the battery when it over-discharges. He writes: The avoidance of overcharging is usually pretty easy to avoid: Just use the appropriate charging system – but overdischarge is a bit more difficult, particularly if the battery packs in question don’t have a “protection board” with them. Lead acid batteries (almost) […]
