Japanese automaker Toyota may soon start the mass production of fluoride-ion batteries that it has been developing, according to Chinese battery media OFweek.
Similar to lithium-ion batteries, fluoride-ion batteries are also a type of rocking chair battery, meaning during the charging and discharging process fluoride ions keep intercalation/deintercalation while travelling back and forth between the cathodes and anodes.
According to Nikkei Asia, despite smaller sizes and lighter weights, the energy density of fluoride-ion batteries is about six to seven times of the lithium-ion counterparts, which means the mileage range could be boosted to over 1,000 kilometres easily. In addition, fluoride-ion batteries are theoretically safer than lithium-ion batteries because fewer dendrites would occur due to the nature of fluoride-ions. This Japanese media estimates fluoride-ion batteries will be put into use in the 2030s, at the earliest.
However, the special features of fluoride-ions limit the applicable temperature range of fluoride-ion batteries. So far, Toyota has been developing remedies for this issue with Japanese research institutes, Kallanish learns.
