Toshiba is charging up with next-generation battery tech that takes more charge faster, even in the cold.

The company is touting a new lithium-ion battery technology that it says can double the capacity of the anode. That means better energy density and faster charging. How much faster? Toshiba said that a 200 mile charge (32 kilowatt hours) in six minutes is possible. That’s three-times what current batteries can manage.

The new battery uses an anode made from titanium niobium oxide. It is less likely to suffer from lithium metal deposition during ultra-fast charging, as well as during cold-temperature recharging. Lithium metal deposition happens during those charging conditions. Lithium builds up on the anode, forming dendrites. When that happens, the cell loses efficiency and suffers from reduced charging and a lower maximum capacity. It can even lead to a short circuit that could cause thermal runaway and a fire or explosion.

The titanium niobium oxide anode is synthesized and arranged using a new method that allows more efficient storage of ions. Combined, the two features allow for quicker charging, better energy density, and better cold weather life. It is what allows the 320 kWh charging that Toshiba says the battery can handle. That’s close to three times the charge rate of what a Tesla Supercharger can deliver.

Toshiba tested the new technology using 50 amp-hour prototypes that it said have double the energy density of the company’s current SCiB battery. Toshiba said that their test batteries maintained 90 percent of initial capacity even after 5,000 charge/discharge cycles. More importantly, it can still deliver that quick charge as quickly as 10 minutes at just 14 degrees Fahrenheit.

The battery is still in development, but Toshiba said that it hopes to have the new battery ready to go in an electric car for 2019.
