Recently, researchers at the Chinese University of Hong Kong have used water-soluble polymers commonly found in skin creams as liquid electrolytes in lithium-ion batteries. Unexpectedly, while improving battery stability, it also reduces manufacturing costs and toxicity. Although lithium-ion batteries have been widely used in mobile devices and electric vehicles, conventional liquid electrolytes are still susceptible to fire or expansion in high-temperature environments, such as the 2016 Samsung Galaxy Note 7 battery failure event. In order to improve the safety of lithium-ion batteries, researchers have put a lot of effort, including the design of built-in flame retardant, so that the electrolyte can have better resistance to impact damage. Another idea is to use a water-based electrolyte that will not catch fire to avoid low voltage and energy density due to water stability issues. Recently, a research team led by Professor Yi-ChunLi of the Engineering Department of the Chinese University of Hong Kong has promoted the development of such batteries by using inexpensive, safe, and environmentally friendly water-soluble polymers. Interestingly, this ingredient can be found in skin creams, toothpaste, medicines, and even food and beverages, it is polyethylene glycol. It is reported that as a new type of water-based electrolyte stabilizer, it can expand the stability window to 3.2V. In contrast, although other aqueous battery designs can increase the voltage, it is often necessary to use high concentrations and toxic salts to stabilize the water molecules. The combination of water, polyethylene glycol and low-concentration lithium salt used in the new design means that the manufacturing cost and toxicity of lithium-ion batteries are kept relatively low. Even better, the new battery can remain stable after 300 charge and discharge cycles. The research team said in a press release: "This discovery provides a new platform for designing liquid electrolytes with large voltage windows and high stability, thereby storing energy more safely, environmentally friendly, and cheaply.
