As reported at the University of California, Irvine (UCI), a graduate student Mei Tai Le accidentally created a battery that does not lose capacity after hundreds of thousands of recharge cycles. Typical commercial lithium-ion battery can withstand 200 to 400 recharge cycles. Experienced graduate student battery within three months of experiments withstood 200 000 charge and discharge cycles without losing the original container.
Mei Le was studying the properties of various materials as a base for batteries with lithium-ion electrolyte. In one experiment, she covered the gold nanowires with manganese dioxide and concluded all in the electrolyte in the form of a very plastic gel such as plexiglass. The resulting battery, became the "miracle", which no one expected. It is assumed that the nanowires plastic gel gives the desired breaking strength, which increases the resistance to wear of the electrodes during charge and discharge, which are accompanied by changes in temperature and hence microdeformations.
Scientists do not yet know exactly how and why such a battery is able to withstand hundreds of thousands of recharge cycles. In front of a huge work to study the phenomenon. Undoubtedly, this is a new approach to science.
