Battery Technology Showcase Highlights Emerging Tech

November 27, 2018

Last month saw the Battery Technology Show roll into London with a host of industry experts debating, sharing their research and hinting at the future of battery technology.

Speakers included experts like Matthew Boulton, COO at Pivot Power; Ross Bruton, Director of Market Intelligence at Smart Energy & Storage; Richard Harrington, MP and Parliamentary Under Secretary of State, Department of Business, Energy & Industrial Strategy, alongside countless other experts.

Opinions were understandably divided, although a few key points did shine through. The general consensus amongst the experts in attendance was that Lithium-Ion batteries are reaching the end of their period of dominance, thanks in part to more advanced battery manufacturing technologies.

But what are the trends which are poised to kill off the Li-Ion battery as we know it? Join us as we take a look.

Solid-State Batteries

Solid-state batteries have long been mooted as a potential successor to Li-Ion batteries, utilising a solid material to enable the transport of lithium ions in the battery. However, a lack of viable material candidates has meant that development until recently has been slow.

Lab-level gains in recent years have yielded a number of advancements which are making solid-state batteries a viable option. This, combined with heavy investment from the likes of Dyson, Renault, Nissan, Mitsubishi and Volkswagen – with an eye to solid-state batteries powering future electric vehicles – has meant that the future looks brighter for solid-state batteries.

Panellists, however, were quick to note that the road to solid-state battery viability is a long one. Commercialisation strategies for these battery technologies will likely be over five years

Sulphur Enhanced Li-Ion

Key industry players have become excited by the possibility of utilising sulphur in Li-Ion battery production in favour of cobalt, nickel and manganese in the cathode.

The idea isn’t a new one and was previously discarded thanks to issues regarding cycle stability. Novel materials, however, have dramatically improved cycle stability in sulphur enhanced batteries, enabling limited commercialisation in niche markets, like satellite production where high energy density is required.

Supercapacitors

Supercapacitors (or ultracapacitors) are regarded as one of the most promising technologies in the battery development world.

Offering millions of cycles before failure, far more than Li-Ion, at the expense of lower energy density, supercapacitors offer much promise with a significant downside. There are companies, however, which are working on the eliminating the downsides.

One plan involves merging supercapacitor technology with solid-state technology, which would solve weaknesses with solid state battery technology like longevity and peak power performance.

Another potential solution is the introduction of graphene supercapacitors, which are currently in production, although details remain thin on the ground on that one.
