Research continues worldwide to develop batteries capable of competing with gasoline and diesel fuel tanks in terms of energy storage density
The latest study in this direction is proposed by City University of Hong Kong, a long-lasting battery without acid. The prototype battery uses an aqueous solution free of acid and lithium ions, improving both performance and environmental friendliness. The new system uses an electrolyte based on magnesium and calcium salts, with an organic polymer acting as the anode and a substance similar to Prussian blue as the cathode. Initial tests appear promising, measuring a capacity of approximately 113 milliamperes per hour per gram of battery, thus exceeding that of many current smartphone batteries. It can withstand up to 120,000 charging cycles, equivalent to approximately 300 years of daily use. There is currently no news on commercialization possibilities.
