A new type of battery can be kept still in cold weather.
This rechargeable battery generates a charge even at a temperature of-70 degrees Celsius, where a typical lithium
Ion batteries that power many mobile phones, electric cars and other devices today do not work.
Batteries that can withstand such cold conditions can help make electronic devices that work in some of the coldest places on Earth or on space rover that surround other planets. Inside lithium-
Ion batteries, where ions flow between positive and negative electrodes, where ions are embedded, then released and returned to the other end through a substance called electrolyte.
As the temperature drops, the ions move slowly in the electrolyte.
The cold also makes it harder for ions to fall off the electrolyte material that sticks to them when they pass through the battery.
Xiaoli Dong, co-author of the research report, explained that ions must leave the substance to integrate into the electrode material
