Chinese researchers develop low-temperature zinc-based batteries

SHENYANG, Sept. 2 (Xinhua) -- Chinese researchers have developed an aqueous electrolyte for zinc-based batteries that are capable of resisting low temperatures, said the Chinese Academy of Sciences (CAS).

Aqueous zinc-based batteries are highly safe and cost-efficient with high energy density. They are expected to be widely used in portable electronic devices and large-scale energy storage fields. However, the low ionic conductivity of aqueous electrolytes at low temperatures makes it difficult for the batteries to operate normally.
