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.
Associate Professor Shinichi Komaba and his team have been working on narrowing this performance gap and recently discovered that sucrose – the main constituent of sugar – can be easily made into a cheap and effective material for the anode of a sodium-ion battery.
