Liacon introduces new 12V Group 31 LFP battery with a 4000+ cycle life

Green Car Congress

In comparison our lithium-iron-phosphate (LFP) batteries have ten times the life, cycling over 4,000 times. Unlike traditional lithium-ion batteries with oxide based chemistries, Liacon’s does not contain expensive and rare heavy metals, such as cobalt and nickel, nor does it contain lead, which is toxic to the environment.

Study finds high-density, low-rise cities such as Paris may be optimal urban form for reducing life cycle GHG emissions

Green Car Congress

A study by researchers at CU Boulder and Edinburgh Napier University finds that high-density, low-rise environments such as those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle. There is a growing belief that building taller and denser is better. —Pomponi et al.
