DOE: US Light-duty electric vehicle miles traveled reached 13.7 billion miles in 2020

Green Car Congress

Beginning in 2014, annual all-electric vehicle eVMT has exceeded that of plug-in hybrid electric vehicles in the US, reaching a new high of nearly 10 billion miles in 2020. Between 2015 and 2020, the eVMT of all plug-in electric vehicles more than quadrupled. Total US Light-Duty Annual eMVT, 2012-2020. Source: DOE.

T&E study finds plug-in hybrids show higher CO2 emissions than claimed

Green Car Congress

Three of the most popular plug-in hybrids in 2020 all emitted more CO 2 than advertised when tested in the real world, according to tests commissioned by European environmental NGO Transport & Environment (T&E). T&E said governments should therefore end the purchase subsidies and tax breaks for plug-in hybrids.

Enhanced performance for TNOx/HRGO hybrid anode for lithium-ion batteries

Green Car Congress

Ti 2 Nb 10 O 29-x /HRGO hybrid was successfully fabricated by introducing vacancies into Ti 2 Nb 10 O 29 (TNO) and hybridizing TNO with holey reduced graphene oxide (HRGO). The synergy effect of above features improves the rate performance of the TNO x /HRGO hybrid. Morphology and rate capability of TNO x /HRGO.
