leading Scientists of the Chinese Tsinghua University and the American Massachusetts Institute of technology led a long and laborious work on extending the life of lithium-ion batteries. However, the desired result, the researchers brought a negligence. Batch of anodes by accident remained under chemical treatment for a few hours longer than necessary. As a result, their strength has increased four times.

the Degradation of the anode material is the main reason for the reduction of battery life. Several hundred cycles of charge-discharge significantly affect the durability of the battery. For anodes of lithium-ion batteries, scientists decided to use aluminum instead of graphite, although it expands and contracts stronger. Because of this, the destruction of the material occurs faster. The researchers decided to stop the formation of the oxide coating on aluminum nanoparticles by soaking materials in sulphuric acid and oxide-titanium sulfate. It replaced the aluminum oxide is more conductive titanium oxide.

One of the scientists accidentally left it soak anodes in a chemical solution for several hours longer than necessary. As a result, the party was spoiled. Fortunately, the researchers did not think to throw it away, and decided to check. It turned out that the new anodes are a shell of solid nanoparticles, in which is enclosed aluminum material. It expands and contracts without damaging the outer cover. This design quadruples the number of cycles of charge-discharge of the batteries.
