  Electrochemical energy storages (EES) are being actively deployed as more renewable energy generation are integrated into the grid infrastructure. Among various EES, Li-ion batteries share more than 80% of EES utilized but reliability and performance have not been clearly evaluated and compared. In this presentation, performance of nine different commercial Li-ion battery cell chemistries under standardized grid duty cycle testing protocols developed by DOE-OE will be presented. The lifecycle de…

  article

  In recent years, zinc has gained significant attention due to its wide availability (fourth-most mined material on the Earth), low-cost nature and recyclability. Moreover, it allows water-based batteries (i.e. Zn/MnO 2 ) that could compete with LIBs for both transportation and stationary applications without safety issues. However, they are not considered rechargeable in practice yet due to the capacity limitation from the cathode materials and the detrimental zinc dendrite formation. Most of th…
