Abstract
This paper proposes the utilization of silicon based polymers for solid state lithium polymer batteries, thereby allowing batteries to be more rugged by decreasing electrolyte volatility and also making them eco-friendly.
Highlights
In today’s world, there is a demand for batteries which have a high energy to mass ratio and till date the only commercially viable options are Lithium based batteries
The cells created generated 0.6V which is 90% of the e xpected value according to the Nerst equation. This is due to contamin a-tion and inaccurate temperature control during the synthesis of the gel which results in many partially blocked or completely blocked pores
This can be circumvented through accurate temperature control during gel synthesis and controlling the amount of contamination
Summary
In today’s world, there is a demand for batteries which have a high energy to mass ratio and till date the only commercially viable options are Lithium based batteries. One of the major drawbacks of Lithium based batteries is that they are not very rugged and can spontaneously ignite when punctured. This is due to the volatile nature of the Lithium salt electrolytes. The polymer synthesized is a class of sub-critically dried aerogels (cross-linked polymers) having the monomer unit of SiO2. This polymer is formed by the polymerization reaction of sodium silicate with Hydrochloric Acid or Tartaric Acid. 0.1 Mol of Sodium Silicate was dissolved in 1015mL of water; 0.1Mol of tartaric acid was added to the previous solution[1][2] This is left at 27 ̊C for a few minutes for the polymerization to complete. The properties of the resultant gel can be adjusted by changing the following parameters:-
