Hyundai, the Korean carmaker turning increasingly to electric vehicles, has teamed with Ionic Materials, a Massachusetts-based battery developer to work on an innovative solid-state battery.  Ionic’s solid polymer electrolyte technology promised to improve battery safety and performance.  Liquid electrolytes are often blamed for disastrous battery fires, so the search for a solid-state alternative is one way to counter the problem. Hyundai’s CRADLE (Center for Robotic-Augmented Design in Living Experiences), “corporate venturing and open innovation business,” is investing in Ionic to gain access to the company’s technology, which also supports lithium-ion cells with no cobalt in their cathodes.  Reducing or eliminating cobalt in their batteries may be a major incentive for Hyundai.  Forbes reports, “Carmakers, such as Germany’s BMW, and electronic gadget …

Rechargeable Alkaline Batteries Seem Inherently Safe

Ionic Materials, A Woburn, Massachusetts-based company, claims to have crafted a battery with an alkaline solid-state electrolyte that successfully resists punctures, cuts and other injuries.  It doesn’t burst into flames like many lithium-based batteries.  In demonstrations, the battery survives 9mm and 25-caliber bullets. A more personal attack takes place with a screwdriver and paper cutter. When a “conventional” lithium battery suffers such assaults, the liquid electrolyte leaks and sometimes causes a short circuit, channeling all the energy into the flammable liquid.  Remember recent hoverboard and airline incidents and a spate of smart phone meltdowns to make you more than a little nervous about the cell phone in your pocket or tablet nearby.  Such thermal runaways on a small airplane are …
