Recently, a research team led by Profs. LI Xianfeng, ZHANG Huamin, and ZHANG Hongzhang from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences developed a new lithium/carbon fluoride battery with high energy density.
The lithium/carbon fluoride battery was tested by a third-party authority, the Institute of Chemical Power for Light Industry. It reported that the energy density of the advanced 10Ah energy-type lithium/carbon fluoride battery could reach to 940 Wh/kg (1150 Wh/L), which rewrote the energy density record of analogue batteries.
The lithium/carbon fluoride battery had an extremely low self-discharge rate, long shelf life (more than 10 years), no electrolyte corrosion hazard and low work temperature (-40 °C). Therefore it presented a superior performance than lithium/thionyl chloride batteries.
Moreover, the advanced power-type lithium/carbon fluoride battery could achieve the high energy density of 550 Wh/kg at a discharge rate of 1C, demonstrating that it had great potential application value in the electronic devices field.
An international team, including members from the University of Science and Technology of China, recently published details in the journal Science about an engineered electrode material with a potential to be used in advanced batteries.
A research team led by Prof. CUI Guanglei from the Qingdao Institute of Bioenergy and Bioprocess Technology has proposed a new class of aqueous electrolytes, called hydrated eutectic electrolytes, to ensure better performance of aqueous Zn batteries.
