Lithium-ion batteries have been a mainstay of the consumer electronics industries for nearly 25 years. Unlike many older energy storage systems, lithium-ion does not describe a specific chemistry but a family of chemistries and a mechanism of operation. As a result numerous types of materials are under the umbrella of lithium-ion batteries that can be modified and developed to meet a variety of end-user goals. Looking beyond-lithium ion, the landscape is less understood and explored. One of our research efforts is to look at non-lithium cation based energy storage chemistries, including the Mg_xV₂O₅ and Mg_xV₂O_5*H₂O systems. This talk will focus on recent developments from our lab in Mg-ion and Ca-ion chemistries with highlighting new types of cathodes, electrolytes, and anode materials^1-5
