CAS Shenzhen Institute of Advanced Technology (SIAT) develops high performance aluminum-graphite dual-ion battery (AGDIB)

Compared with conventional LIBs, AGDIB shows an obvious advantage in production cost (~ 50% lower), specific density (~1.3-2.0 times), and energy density (~1.6-2.8 times). It delivers a specific energy density of ~222 Wh kg−1 at a power density of 132 W kg−1, and ~150 Wh kg−1 at 1200 W kg−1, as compared to commercial LIB (~200 Wh kg−1 at 50 W kg−1, and ~100 Wh kg−1 at 1000 W kg−1) and electrochemical capacitors (~5 Wh kg−1 at 5000 W kg−1)
