TyFast develops lithium vanadium oxide anode battery to achieve 3-minute charging and 20,000 cycles

Most lithium-ion battery research focuses on increasing energy density, but startup TyFast is doing the opposite, compromising on battery capacity to achieve fast charging and a longer life cycle.

According to foreign media reports, TyFast claims that its vanadium anode battery can charge 20 times faster than ordinary lithium-ion batteries, extend its service life 20 times, and is designed to be fully charged within 3 minutes and support 20,000 charging cycles. It is reported that the battery can still provide 80% to 90% of the energy density of current batteries.

The battery's focus is a new lithium vanadium oxide (LVO) anode, which increases the speed of ion flow by nearly 10 times compared to graphite anodes and shrinks and expands less during charge and discharge, which can reduce mechanical damage to the anode and help extend battery life.

GJ la O', CEO and co-founder of TyFast, said: "Our focus is on enabling 20 times faster charging and 20 times longer life than current lithium-ion batteries with our vanadium anodes, meaning that with the same run time, the battery enables faster charging and longer life with negligible compromise in size and energy density."

The battery also has disadvantages, namely that the same mass of LVO contains fewer ions than graphite and is more expensive, about twice as expensive as a graphite anode. But because LVO has a longer life cycle, it can make up for its high cost. The prototype battery manufactured by TyFast has been proven to last more than 2,000 charging cycles and can be fully charged in 15 minutes. By the end of this year, TyFast plans to achieve 20,000 cycles and control the charging time to less than 3 minutes.
