| Abstract Scope |
To significantly boost the energy of the state-of-art lithium ion (Li-ion) batteries, one of the most effective approaches is to replace graphite anode with Li metal which is ultralight but energy concentrated. However, its thermodynamically instable nature in liquid electrolytes causes many well-known problems such as dendrite formation which plagues the implementation of the proposed technology. This talk will discuss the fundamental challenges of utilizing Li metal anode in at cell-level. A Li metal prototype pouch cell with 350 Wh/kg energy with more than 350 cycles will be demonstrated. The key fundamentals that enable the long-term cycling of Li metal anodes in pouch cells are discussed and the root causes of the poor cycling of realistic Li metal pouch cells have been revisited. A series of fundamentally new insights have been provided to inspire scientific innovations to tackle the real challenges of developing next-generation battery technologies. |
