LG Chem Creates Curved, Stepped, and Cable Batteries
LG Chem followed LG Display's curved OLED screen announcement with one of its own: curved batteries. The company says it has successfully designed batteries that can be formed into shapes other than flat rectangles. The three new battery designs are curved, stepped, and cable. The curved batteries use what LG Chem calls Stack & Folding technology, which is used to reduce the stress on the curved battery pack. LG says this battery is a perfect match for devices with curved screens. Stepped batteries are made of two batteries that are added on top of one another to create a step. LG Chem says this battery type can be used to fill what might otherwise be dead space in certain device designs with additional battery capacity. Last, cable batteries will be ideal for devices that are bendable or wearable, says LG Chem. Its cable batteries can be tied in knots, won't heat up when used, and are waterproof. LG Chem believes this type of battery will be a perfect match for devices such as smartwatches. LG Chem said its stepped batteries are already being used in some devices, such as the LG G2. The curved batteries are expected to power LG's next wave of smartphones. Cable batteries won't be ready for consumer-grade gear for another year or so.

AT&T's Latest GoPhone Runs On AA Batteries
AT&T today announced the SpareOne Emergency Phone, a simple handset meant purely to serve as a backup phone for critical situations. The SpareOne runs on AA batteries, rather than a rechargeable lithium-polymer power cell.
Solid State Batteries Could Double Performance
Sakti3, a Michigan-based battery company, claims to have created new technology that will double battery life compared to today's lithium ion batteries. Sakti3's approach is entirely different from standard batteries.
MIT Spinout Claims to Double Battery Life
A company called SolidEnergy Systems, a spinout from MIT, says it has new battery technology that will double the life of lithium-based power cells. The breakthrough involves a battery that replaces the traditional graphite anode with a thin, lithium-metal foil.
