Over 1.9 million plug-in electric vehicles (PEVs), including electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), have been sold in the USA since 2010. [1] In the fourth quarter of 2021, the PEV market share grew to 10.9% of total new light-duty vehicles sales in the USA. [2] Global market share of PEVs has also shown robust growthglobal PEV sales in 2021 rose by around 108% compared to 2020. [3] It is anticipated that the PEV growth will continue to increase in coming years because of national and international climate-friendly policies. In 2019, the European Commission adopted CO 2 emissions performance requirements, for example, European Union (EU) Regulation 2019/631. The CO 2 emission regulation forces automotive manufacturers in the EU to ensure 40% of their new car sales to be zero-emission vehicles (ZEVs) or low-emission vehicles (LEVs) by 2030. [4] Moreover, California will require that 100% of in-state sales of new passenger cars and trucks are ZEV by 2035 under Section 177 of the Clean Air Act. [5] Nine other states including New York, New Jersey, and Massachusetts in the USA adopted goals for ZEV along with California's standard. [6] Similar to California's ZEV mandate, China's New Energy Vehicle (NEV) mandate policy took effect in 2018 to promote new clean energy vehicles and provided additional compliance flexibility to the existing fuel consumption regulation. [7,8] According to China's NEV Mandate policy, the car manufacturer would lose credits if they failed to meet CO 2 standards, which would result in losing the license to sell new vehicles in China. In response to regulation and policy, automakers have accelerated their plans to become fully electric. [9] For example, Ford targets 40% of its global vehicle sales to be EVs by 2030, [10] and General Motors plans to end production of internal combustion engines (ICEs) and shift its entire new fleet to EVs by 2035. [11] Three key advancements are viewed as necessary to facilitate PEV adoption levels prescribed by the different mandates and releases: increased battery specific energy which will lower overall battery cost and increase range, [12,13] the ability of batteries to charge in a short duration such as extreme fast charging (XFC, 10 to 15 min full charge), [14] and the development of robust charging infrastructure. [15][16][17][18] Jointly these advances will more closely align the experience of an EV user with those from an ICE vehicle. Here we survey the literature and scale the advances from the cell level to the vehicle level to provide insight into potential advantages and challenges which will arise from the significant advancements that have been made in Battery R&D. First, the
