Questions raised about lithium-ion cell’s claim to fame - lithium ion rechargeable battery

The estimation of lithium is inaccurate
A new study reports that the remaining power of the ion battery may come from the failure to fully charge and discharge the battery.
The surprising findings published in April 14 may affectand-
The electric car industry is coming as it needs to be accurately estimated how far the owner can travel before it needs to be charged.
Some rechargeable batteries such as nickel
Cadmium and nickelmetal-
Hydrogen batteries, when the user repeatedly charges without allowing full discharge, lose capacity over time. But lithium-
It is believed that the ion batteries widely used in laptops, smartphones and electric vehicles are not affected by the user's charging habits.
Sasyoshi Sasaki, a physicist at the Toyota central research and development laboratory in Japan, and colleagues at the Paul Scherrer Institute in Switzerland measured the voltage on an electrode because the battery was repeatedly charged and discharged.
After a charge that was not completed, the next charge produced a surprising voltage spike.
The sensor may measure the voltage blip and overestimate the amount of power remaining in the battery.
Fortunately, the impact is manageable, says Paul Braun, a material scientist at the University of Illinois at Urbana.
Champagne not involved in the study.
Not long-
Sasaki's team found that the long-term impact on battery capacity and full charging of the battery eliminated abnormal voltage readings.
Understanding this phenomenon will enable car battery makers to design better battery packs and sensors to accurately measure mileage until it is emptied, Braun said.
