The Ultra Capacitor Battery (UCB)

INTRODUCTION

The Ultra Capacitor Battery (UCB) is a high-performance lithium hybrid capacitor battery designed for universal application in the energy storage industry.

Traditional ultracapacitors have long been heralded as the future of energy storage. The vast graphite or synthesised graphene electrostatic surface area within ultracapacitors facilitates extremely fast charge and discharge with no theoretical degradation and predicted cycle life of 10+ million ⥁ (cycles). The upside to electrostatic storage is very high peak power (W), the downside is comparatively low energy (Wh) density relative to a traditional lithium ion battery.

The Quest

The quest for the ultimate battery has driven scientists and engineers for decades. Imagine the ultimate battery paired with low cost variable renewable generation sources such as PV solar panels, wind turbines, hydro and biogas generators, designed to deliver base load energy at a significantly lower cost and with far lower net emissions than traditional non-renewable energy power stations. New non-renewable energy power station’s plans would be stopped in their tracks and the full transition to clean energy would begin.

The Team

Arvio’s team has been involved in energy storage system design, implementation and software development since 2011. The recent launch of Arvio’s Ultra Capacitor Battery (UCB) is setting the new standard for the change to a 100% clean energy generation.

The Materials

To enhance the energy density of an electrostatic ultracapacitor, 30-60nm Ø spheres of lithium titanate oxide (Li4Ti5O12) form the cathode while highly porous graphite 5,000 -15,000nm Ø spheres form the anode. This increases the energy density (Wh) and decrease the power density (W) of the hybrid cell.

The nanospheres allow for safe mechanical movement of the anode and cathode substrates as temperatures and state of charge change delivering a highly durable and long-lasting cell.

Some lithium ion batteries with an SEI (solid electrolyte interphase) layer carry a risk of dendrite growth piercing the fragile SEI layer between the anode and the cathode as the cell ages or is mistreated. This can cause thermal run away or fire. Thanks to technological enhancements, the SEI layer is not required in the hybrid cells, further enhancing the safety and removing the risk of thermal runaway and fire.
