Kathmandu. Chinese scientists have discovered an important reason why ‘lithium batteries’ fail. This discovery is believed to make a major contribution to the field of electric vehicles.
A lithium battery is a type of rechargeable battery that uses lithium ions for energy storage and utilization. It consists of two electrodes (anode and cathode), and between them, lithium ions move in one direction when charged and in the other direction when discharged.
Lithium batteries are lightweight, long-lasting, fast-charging, and have high energy capacity, making them widely used in mobile phones, laptops, electric vehicles, and solar power systems. China has become a leading country in lithium battery production and technology. China is making further progress in new battery technology, competing with countries such as Japan and Korea in friendly competition.
Battery failure causes While ordinary batteries use liquid materials, lithium batteries use solid materials. When lithium expands and contracts during charging, such solid materials can crack, which affects the battery.
Scientists from Tongji University and Huazhong University of Science and Technology have found through research that lithium metal can weaken with repeated use, which can lead to battery failure. The study was published in the international scientific journal Science. It is believed that this will help estimate the life of the battery.
A positive sign for the future: Such batteries are expected to be widely used in the coming days as they can store more energy than traditional batteries, are smaller in size, safer and have a longer lifespan.
A collaboration is underway between Chinese scientific teams and leading companies. Some companies plan to start small-scale production by 2027, and it is said that it is likely to be widely used around 2030.
Experts have expressed confidence that China will make better progress in this new technology, as it has a strong production capacity, market, scientific resources and technology.
