Lithium-ion batteries possess a high-energy capacity making their structure and uses ideal for miniaturized storage hosts that project high levels of power. Lithium-ion batteries are widely used in mobile applications such as smart phones, tablets and electrically-powered vehicles.
As a secondary battery technology that facilitates energy flow during charge and discharge, lithium-ion batteries are structured around a cathode and anode that enable the absorption of lithium-ion particles upon the application of current. In the reverse, lithium-ions desorb into an electrolyte solution when current is not being applied.
Unlike legacy alkaline and zinc battery technologies, the properties of lithium ions facilitate flow towards the cathode component during application use. This flow is reversed during a charge cycle as ions are absorbed back into the anode. The process of recharging allows for many cycles, thereby enhancing the lifespan of a battery.
As consumer preferences evolve on the advent of mobile and wireless technologies, energy source efficiencies continue to present design units and global manufacturers with a number of significant obstacles.
Bridging the gap between the potential possibilities and current limitations is highly dependent on creating a more robust power source that can withstand both the charging and consumption requirements demanded by advancing technologies. Overcoming these obstacles will likely uncover a more technologically-advanced era for mankind as sectors develop to align with evolving consumer preferences.
Graphene battery technology is structured similarly to that of more traditional battery construction in that two electrodes and an electrolyte solution are critical to the charge and discharge flow of ions. The major difference between the way graphene batteries function is in the composition of the cathode and/or anode.
The structural change is primarily targeted around the cathode component, which in conventional battery makeup, is composed purely of solid-state materials. Replacing solid-state components with a hybrid of solid-state metallic material and graphene presents a range of possibilities whereby composite structures can be tailored to suit the requirements of specific user applications.
Incorporating graphene-lithium-ion hybrid chemistries as part of a battery structure provides a significant number of performance-enhancing benefits.
As a single atom thickness sheet, graphene can be layered with any number of nanoparticles that accept the flow of lithium ions during a charge or discharge cycle.
The possibilities for end-use are numerous and, with such versatility, graphene lithium-ion batteries can be engineered to meet the specific requirements of a range of applications.
