This non-toxic battery lasts a decade, could be renewable energy’s missing piece Anthropocene, by Feb 23, 2017 “……Researchers at Harvard University have developed a new kind of low-cost battery that can run for more than 10 years with no maintenance. It is also non-toxic and inexpensive, to boot. The technology could make grid-scale renewable energy storage a reality, the researchers say in a paper published in the journal ACS Energy Letters…….
|The battery loses only 1 percent of its capacity after over 1,000 charge cycles, which is much longer than lithium batteries. The researchers also calculated that if the battery was charged and discharged completely once a day, “we would expect it to retain 50 percent of its energy storage capacity after 5,000 cycles, or about 14 years.” http://www.anthropocenemagazine.org/2017/02/low-cost-long-lasting-battery-to-store-solar-power/
