Breakthrough Battery Technology: $65/kWh

sb-pb-battery

US researchers at the Massachusetts Institute of Technology have developed a liquid metal battery that could fulfil that role. Such a battery would lower the overall costs of energy storage, and have the advantages that they are mechanically simple and don’t take up much space… Indeed, the team’s experiments with this novel storage system carried out at 450°C displayed a current density of 275mA/cm2, with a cycling efficiency of 98% on charging and 73% ‘round-trip’ energy efficiency… The team’s experiments completely charging and discharging their battery over 450 cycles over 75 days suggests that the battery will still have 85% of its initial storage capacity after 10 years active service… The team adds that at today’s prices, the electrode materials costs are approximately $65/kWh.

Editor: is this is true and no serious (environmental) disadvantages come with this technology, this could mean the final breakthrough for wind and solar.
