A method of conventional chemical reaction to prepare delithiated cathode materials of Li-ion battery has been introduced. The cathode material of Li-ion battery was mixed with oxidizing agent Na_2S_2O_8 in water, and the liquid was stirred continuously to make the chemical reaction proceed ...

Each cell of a battery stores electrical energy as chemical energy in two electrodes, a reductant (anode) and an oxidant (cathode), separated by an electrolyte that transfers the ionic component of the chemical reaction inside the cell and forces the electronic component outside the battery. The...

Very few studies in the literature have focused on the chemical reaction mechanism responsible for failure during overcharge. This is, however, of great interest because a Li-ion battery can produce reactions in a sealed container and is thus a highly reactive system. Here, experimental approaches...

When a Li-S battery is running, the electrochemical reaction of sulfur cathode will produce soluble lithium polysulfides (LPS). Some of the LPS will pass through the separator to lithium metal anode surface and be reduced to insoluble Li2S2 or Li2S. Since this part of S is unable to ...

Temperature is known to have a significant impact on the performance, safety and cycle lifetime of lithium-ion batteries (LiB). However, the comprehensive effects of temperature on the cyclic aging rate of LiB have yet to be found. We use an electrochemi
