What’s Happening in EV Battery Technology

Driivz

From how much they cost and weigh to the amount of power they store and how long they take to charge, electric vehicle (EV) batteries have a significant impact on EVs themselves, the EV industry as a whole, and ultimately EV buyers. Anodes are most commonly made of graphite.

Battery Advances Over the Next Ten Years

My Electric Car

For example the volumetric energy density of lithium-ion batteries has increased eightfold since 2008, from around 55 watt-hours/litre to 450 watt-hours/litre in 2020. At the same time the cost of lithium-ion battery packs declined 87% between 2008 and 2021. This could potentially lead to electric cars with a much longer range.

PNNL licenses three technologies via Startup America; batteries, fuel cells and buildings

Green Car Congress

Vorbeck, a manufacturer and developer of applications using its proprietary graphene material ( earlier post ), optioned the technology for use in a graphene-based electrode for lithium-air and lithium-sulfur batteries. Each year, pests cause many millions of dollars in damage to homes and commercial buildings.

NRC report concludes US LDVs could cut oil consumption and GHGs by 80% by 2050; reliance on plug-ins, biofuels and hydrogen; strong policies mandatory

Green Car Congress

Achieving those goals will will be difficult—but not impossible to meet—and will necessitate a combination of more efficient vehicles; the use of alternative fuels such as biofuels, electricity, and hydrogen; and strong government policies to overcome high costs and influence consumer choices. —Douglas M.
