Sony Improves Smartphone Battery Life? Huawei Shows Off!
Technology giant, Sony Corp has announced that a new battery life technology for smartphones is being developed to replace standard lithium-ion batteries, according to Japanese newspaper, Nikkei Technology.
Mobile phone technology and design changes every year, but what smartphone users want is prolonged battery life. The technology seemed to plateau in recent years.
Sony promises to increase the energy density of today's lithium-ion batteries by 40 percent, revealed BGR.
The company hopes its "super batteries" will be available to all manufacturers and that it will go on sale by 2020. The batteries will use sulfur at the negative electrode and the usual lithium at the positive end. This will provide an energy density per unit volume of 1,000Wh/L. Most lithium-ion batteries have approximately a 700Wh/L energy density.
The new technology will be first used for smartphones when these hit the market. Sony has not resolved the technical challenges just yet. Lithium -sulfur batteries are susceptible to "heat generation or ignition," cited Tech News Today.
The company however, believes they are close to solving this issue. Magnesium, a common element, will make the company's new batteries, inexpensive to produce.
Last month, Huawei announced their new battery can be charged to 50 percent in five minutes. The 3,000mAh (milliampere hours) batteries were first seen at the 56th Battery Symposium in Japan. The battery size is similar to the ones inside most smartphones.
A battery with a smaller 600mAh capacity was also shown. This reaches 68 percent charge in two minutes.
"Huawei is confident that this breakthrough in quick charging batteries will lead to a new revolution in electronic devices, especially with regard to mobile phones, electric vehicles, wearable devices, and mobile power supplies," read a news report on the Huwaei Fans blog.
"Soon, we will all be able to charge our batteries to full power in the time it takes to grab a coffee."
Huawei claimed that using graphite atoms that are bonded to the anode does not sacrifice usage life and the amount of energy it can store, reported the Daily Mail.
