Apple Patents Non-Exploding Batteries  Apple products are really
pretty, so it's quite a shame when they explode. More than once.
So I'd say this patent for non-exploding batteries is definitely
a move in the right direction.  When a battery is exposed to
direct sunlight or intense heat, gas buildups can occur and
cause the battery to swell or, even worse, blow up. Apple's new
design would include "special battery pouches" with the
intention of avoiding fire hazards:  Apple's patent application
outlines a battery cell which includes a weakness for relieving
pressure. This battery cell may include a jelly roll comprising
layers which are wound together, including a cathode with an
active coating, a separator, and an anode with an active
coating. The jelly roll may also include a first conductive tab
coupled to the cathode and a second conductive tab coupled to
the anode.  It's likely that the jelly roll would be inside a
flexible pouch and the two tabs would protrude from it so they
could connect to the batter
