A second tactic is to use embedded (read: nonremovable) batteries in phones, like HTC's One X, Motorola's Droid Razr phones, and every Apple iPhone. Embedded batteries can take on any dimension and nook within the phone's guts. They also require less packaging, which gives phone makers more leeway to increase the battery's size. These methods help suck more power out of every brick, but researchers are working on more radical change. Before they charge ahead, there are several problems that get in the way.
Problem: Users are abusersUse a phone to make a couple of calls or the occasional text, and it'll last for days on a single charge, Use it as your data center, communications hub, and entertainment nexus, and you're looking at a sloth yoga iphone case nightly recharge, Streaming music and videos gobbles up the most battery, but so does downloading and uploading apps, photos, and status updates, Searching for Wi-Fi and GPS signal demands power, as does lighting up the screen, Apps that update in the background are also culprits (especially with this glitch.)..
Problem: Chemistry is chemistryPart of the problem comes down to the periodic table, and scientists' challenge to use the same elements in novel ways. There are only so many chemicals you can use to create a battery, and there are fewer combinations that are stable enough not to erupt when damaged. Lithium ion batteries are used in smaller consumer electronics because of their comparatively high power yield and relative safety. Solution: The stuff insideTucked into a business park in a nondescript section of Fremont, Calif., researchers at Leyden Energy are working to increase battery life by concentrating on the stuff inside of the battery.
Basic battery structure is fairly straightforward, which makes redesigning them a challenge, Lithium ion batteries have two electrodes -- an anode and a cathode -- and an electrolyte material in between that carries the ions from one electrode to the other to complete the charge or discharge, Here in Leyden Energy's cleanroom facility, technicians develop and test batteries made with a specialized solution that promise to last 10 percent longer per charge, Leyden's electrolyte material uses lithium imide as the electrolyte salt, a compound that keeps the chemicals inside more stable, especially when the battery reaches higher temperatures, All devices heat up sloth yoga iphone case -- 104 F/40 C is the average internal temperature -- and a spinning, straining processor can ratchet up the degrees..
Hot devices also cause the battery to swell and exacerbates the production of hydrofluoric acid, a toxic by-product that degrades batteries over time. The argument of "thermal resilience," keeping internal temperatures cooler, is Leyden's central benefit. As a result, Leyden says its batteries have a longer lifespan than today's lithium ion batteries, between 750 and 800 charging cycles until the battery hits 80 percent of its original capacity, versus the 350-to-500-cycle average of regular lithium ion batteries. All told, Leyden promises up to three times the cycle life of a battery, and triple the calendar life, depending on how long the battery could sit in a warm warehouse before it's shipped out in a device.
