Researchers at the Tokyo University of Science have turned to sugar as part of a continuous effort to control Japan’s growing import costs associated with building lithium-ion batteries. It seems that sugar may be the missing ingredient for building rechargeable batteries that are more robust, cheaper, and capable of storing more energy.
Lithium-ion batteries are ubiquitous in portable electronics, but concerns over rapidly growing demands for lithium – a metal that is mainly found in politically sensitive regions such as Bolivia, Chile, Argentina and China – have pushed countries like Japan to try and develop viable alternatives for a cheap, high-performance rechargeable battery.
Sodium-ion batteries have been put forward as one of the possible successors to lithium-ion technology. Among their advantages, they promise to be more durable and cheaper to manufacture. However, being in an early developmental phase, their performance isn’t currently quite up to par.
