A sugar battery is an enzymatic biofuel cell type rechargeable battery that is sugar-based. In 2014, researchers at Virginia Tech developed a battery that is run on sugar and closely competes with lithium-ions. They have an energy storage of 596 Ah kg−1, which is more than lithium-ions. If these batteries are proven, they could be used as soon as three years from now. These batteries can be used to power a cell phone for ten days, unlike the current li-ions that can only be used for one day. These biobatteries are cheaper to make, refillable, environmentally friendly and nonflammable.
