Said subjects are being analyzed in this work. Also, the authors have attempted to show that in order to be suitable for lithium-ion applications, a carbon-based active material has to meet a complex number of physicochemical and electrochemical characteristics. A simple check of galvanostatic behavior, which is often used today to conclude about carbon s suitability for lithium-ion battery technology, is rarely enough for making an accurate assessment. 

LiVMoOe was successfully synthesized using the conventional solid-state reaction method, and its chemical and physical properties were examined by several analytical methods. We have shown that LiVMoOe does not possess good structural characteristics for a lithium half cell (Li/LiVMoOe) as a cathode in non-aqueous electrolyte environment. Furthermore, we suggest that LiVMoOe may instead be considered as an anode material of choice for developing rechargeable lithium-ion battery technology. 

The rates of the electrochemical reactions that proceed at the two types of plates depend on current density. Increase of formation current is associated with increase of the heat effects of the reactions and of the Joule heat released. This causes the temperature in the battery to rise. And battery temperature is one of the technological parameters that should be kept within definite limits to ensure high battery performance characteristics. So the basic dependencies that have to be monitored and controlled during the formation process are current, battery voltage and temperamre as a function of formation time. 

Apparently, these commercial lithium-ion polymer batteries have characteristics, such as reduction in thickness and improvements in safety, which make them very appealing for the modern consumer electronics markets, particularly the new generation of cellular phones. This may lead to the conclusion that the evolution of the lithium-ion battery technology will be focused on polymer configurations with an output that is expected to soon experience a substantial share in the electronics market.
