A graphic depiction of Next-Battery's improved cathode and anode shows how its unique nano-structures allow more lithium-ions (Li+) to be neatly packed into the electrodes, since they have to move back and forth between the cathode and anode during the discharge and charge actions.
A short explanation of a lithium-ion battery is that they are made of two electrodes – a cathode (positive) and the anode (negative) – and an electrolyte through which the electric charge flows as the lithium ions and the electrons move between the cathode and anode when the battery charges and discharges.
Conventional cathodes use compressed powders of various metal oxides in a less structured form to accept the lithium-ions (Li+).
The challenge with conventional cathodes is to avoid damage to the cathode structure during repeated charge/discharge cycles, since infiltrating the structure with Li+ can cause swelling or surface damage in the process. Similar issues occur in conventional graphite anodes, which can be damaged or swell in the process of intercalation and de-intercalation of Li+.
