Most smartphone users crave for more power in smartphones and there are many smartphones with battery capacity greater than 5000 mAh. A good solution to the incessant need for more power is the Fast Charge technology which allows users to achieve a full charge within a few minutes. However, many do not know that extremely low temperatures have adverse effects on normal lithium-ion batteries that are found on most smartphones. Research shows that at -20 degrees temperature, a Lithium battery will lose 50% performance within a few minutes which causes the smartphone to slow down or shut down unexpectedly. This means that users in the far north will be having this battery challenge.
However, reports out of China suggests that some Chinese scientists have developed a lithium battery that is resistant to remarkably cold temperatures. The report states that this battery is usable even at -70 degree temperature. The team from Xia Yongyao, Fudan University used low-temperature conductive ethyl acetate as electrolyte and the electrode are a dual organic compound. This configuration ensures that the organic compounds do not react with the electrodes which is one of the setbacks of conventional lithium batteries in cold conditions. Although this battery build materials are affordable and environmentally friendly, the scientists admitted that the commercialization of this battery might be a problem because the new cell’s energy density is too low to match today’s lithium batteries.
