With a potential lifespan of 10 to 20 years, Professor Zhongwei Chen’s next-generation rechargeable batteries are set to put the Energizer Bunny to shame.
Dr. Chen and his team are developing next-generation batteries and fuel cells. They are working on two types of batteries that are destined to be longer lasting and more efficient. One of these batteries is a rechargeable zinc battery that uses renewable energy, such as solar and wind. It could also be cost effective, which means that everyone could use it in the future.
Dr. Chen and his team are using novel materials to upgrade the traditional battery. He says that the key is to use silicon-based materials instead of graphite materials, which are currently being used in the commercial battery. Why? Silicon’s energy density is 10 times higher.
The result is a potential 150% energy density increase compared to its graphite-based lithium battery counterpart, which is currently being used to power electric cars and our cell phones. With the popularity of electric cars on the rise, companies such as Tesla and Panasonic are already looking to move beyond the limitations of the lithium battery.
Dr. Chen explains how he plans to solve the problems associated with the traditional battery as we move forward to meet the increased energy demands of the future.
