Breakthrough for lithium-sulphur batteries

A cell technology holding 900 Wh/kg – three times the energy density of state-of-the-art lithium-ion battery chemistries – that is safer and cheaper thanks to the use of abundant and easily accessible sulphur for the cathode in place of nickel manganese cobalt oxide (NMC) is an exciting prospect (writes Peter Donaldson). Batteries that use sulphur […]

High-speed marine motor addresses critical need

Rapid acceleration may not be the first thing that comes to mind when considering marine vehicles that serve the offshore industries, but it is important because it increases their operational limits, enabling them to be deployed for longer in higher sea states (writes Peter Donaldson). That is one of the key selling points of Walker […]

Making the cases for battery transport

As the EV industry grows, the logistics of moving major components – particularly batteries – between facilities has to be closely considered, argues Olivier Saada, business development manager for containers at battery transport packaging specialist Corplex (writes Peter Donaldson). EV batteries are considered dangerous goods and fragile items, and the company makes cases that are […]

Wireless charging by magnetic induction

Andy Daga, founder, president and CEO of Momentum Dynamics, wants to make charging EVs easier than refuelling IC-engine vehicles while enabling practically unlimited range in day-to-day driving, at least in urban and suburban environments (writes Peter Donaldson). The company is now rolling out its wireless charging system based on magnetic induction technology for large vehicles […]
