Automotive powering batteries are usually designed for a long-term life circle which is more than 10 years thus the corresponding stability is the utmost important object. Silicon batteries which need silicone oils are one of them. However, the research of silicon batteries is few and lack of information. Now most of the researchers of negative silicon cells focus more on the volume changes during the recycling processes and the degeneration aspect is not paid much attention.

Today the powering cells which use graphite negative electrodes could be stored over 15 years during a warm environment which is between 20℃ to 40℃ which means even though the battery is inactive it will still contain 80% of total energy storage. Silicon is more applied as the add-on chemicals to enhance the batteries’ energy density rather than a formal electrode material.

It is according to this situation, Christopher S. Johnson from the U.S, has discussed a series of researches on reactions of silicon. All of these refer to the chemical properties of silicon lead to the increment of degeneration degrees of batteries. Thus, it is necessary to put more efforts on studying the chemical parts of silicon. Christopher also indicates some opinions and suggestions to improve the corresponding known shortages. The relevant things are published in Natural Energy in the title of  “Calendar aging of silicon-containing batteries”.
