VW testing battery that could boost energy density 4x
March 22, 2014


VW testing new batteries

Volkswagen is bench testing a new battery chemistry that it says could store up to 80 kWh of energy in a similar volume to that of the current eGolf’s 26.5 kWh battery pack.
Speaking at the Geneva Motor Show, VW representative said that the company has tested lithium-ion batteries with its existing cell supplier, Sanyo, with capacities up to 37 kWh, but “an 80 kWh unit is under development using our own technology. It would provide between three and four times the battery power in a given package.”
VW refuses to name the battery chemistry, but doesn’t deny it is based on lithium-air technology. IBM, BMW and Toyota are known to also be developing Li-Air battery technology
