Inexpensive solid-state batteries giant sufficient for cell telephones and drones have been promised for a very long time however appear to all the time be just a few years away from manufacturing. On this case, Taiwan based mostly Prologium despatched [GreatScott] samples of their Lithium Ceramic batteries (LCBs) to test, and despite the fact that they’re not but business merchandise, who’re we to refuse a peek at what they’ve been as much as? They despatched him two sorts, versatile ones (FLCBs) and better capability stiff ones (PLCBs).
The FLCBs had been rated at 100 mAh and simply 2 C, each small values however nonetheless helpful for wearables, particularly given their flexibility. Performing some harmful testing, he managed to maintain an LED lit whereas flexing the battery and slicing away at it with tin snips.
Switching to the thicker 7.31 Wh PLCB, he measured and weighed it to get an power density of 258 Wh/L and a particular power of 118 Wh/kg, solely about 2/3rds and 1/2 that of his LiPo and lithium-ion batteries. Repeating the harmful assessments with these ones, the LED turned off and smoke appeared whereas slicing and hammering a nail by way of, seemingly as a result of shorts attributable to the electrically conductive tin snips and nail. However as soon as the snips and nail had been moved away, the smoke stopped and the LED lit up once more. Overcharging and short-circuiting the batteries each prompted the solder connecting the wires to them to soften however nothing else occurred. Quickly discharging by way of a resistor solely resulted in a gradual voltage drop. Clearly, these batteries are a lot safer than their LiPo and lithium ion counterparts. That security and their flexibility appear to be their present fundamental promoting factors ought to they develop into obtainable for us hackers. Take a look at his assessments within the video under.
In the meantime, we’ll need to be content material with the occasional tantalizing report from the labs corresponding to this one from MIT of a long battery life and one other from one of many co-inventors of the lithium-ion battery which uses a glass electrolyte.
