Collaborate Disseminate
Battery advances are starting to come thick and fast as massive investment in the segment begins to bear fruit. California’s Enevate has been chipping away at silicon anode technology since 2005, and now the company says it’s managed not only to achiev… Continue reading Enevate’s silicon-anode batteries promise ultra-fast EV charging
At 50 percent smaller by volume than a typical lithium-ion battery, Samsung’s prototype solid-state pouch cells could enable 500-mile electric car ranges and cycle lives over 1,000 charges in a much safer package.Continue ReadingCategory: Energy, Scien… Continue reading Samsung reveals long-range, solid-state, EV battery prototype
We’re pretty sure that [Luke] took Uncle of the Year last Halloween when he made an RGB LED princess dress for his niece. He recently found the time to document the build with a comprehensive how-to that’s just in time for Halloween ’17.
[Luke] made the system modular so that his niece could use it with any dress. The RGB LED strips are actually fastened down the inside of a petticoat — a fluffy, puffy kind of slip that’s worn underneath the dress. The LEDs face in toward the body, which helps diffuse the light. [Luke] first attached the strips …read more

Researchers have built a prototype lithium-sulphur battery that — when perfected — could have up to five times the energy density of current lithium-ion devices. Researchers in the UK and China drew inspiration from intestines to overcome problems in the battery construction.
In your intestine, small hair-like structures called villi increase the surface area that your body uses to absorb nutrients from food. In the new lithium-sulphur battery, researchers used tiny zinc oxide wires to form a layer of material with a villi-like structure. These villi cover one electrode and can trap fragments of the active material when they break …read more
