Batteries

The rapid penetration of electric vehicles has led to questions on its most expensive component - the battery. What happens to the batteries after 8-10 years of service when they retire from electric vehicles due to capacity fade?

The first batch of electric vehicle batteries are reaching their retirement age and the next ten years will see a huge increase in the volume of retired batteries. What will happen to the huge amount of used EV batteries? IDTechEx has recently released the latest report named Second-life Electric Vehicle Batteries 2020-2030.

Shortage of lithium-ion batteries is probable. Too few gigafactories. Too many burning batteries: factories shut to sort out their problems. The US-China trade war cuts off materials. Inadequate lithium or cobalt mining.

In electric aircraft, motor power-to-weight ratio is paramount for endurance, the main constraint on sales. You cannot lug ever more battery weight to get range. Indeed, better motors mean less battery in a land, water or air vehicle. The new IDTechEx Research report, "Electric Motors for Electric Vehicles: Land, Water, Air 2019-2029" explains the new emphasis on power-to-weight ratio with good efficiency.

IDTechEx will be hosting a free webinar on Tuesday 6 November titled Solid-State Battery Update.

Cleantech Hub reports that a mere 13% of lead acid batteries are recycled in Nigeria. Yet there is a mini-grid revolution about to take off in Nigeria, such as the World Bank and the Rural Electrification Agency $350 million project as well as other investments into the sector, driving more batteries.

Provides peak power support to 3V coin cell batteries and eliminates need for 2.7V LDO regulator for less expensive, smaller, more energy-efficient designs with extended battery life.

Li-ion Batteries are the talk of town in the tech industry, but clarity on the subject is scarce, and very often the word "Battery" is used interchangeably to indicate those relying on the reversible shuttling of lithium ion (Li-ion batteries, or LIB), and many other different energy storage technologies that have little in common with each other.

IDTechEx analysts have long warned that the leading lithium-ion battery manufacturers have been taking risks in their headlong redesigns to obtain higher energy and power density, lower cost per kWh and ironically better safety, for example from less-flammable and non-flammable electrolytes.

New Zealand leads the world in zero emission renewable grid electricity now at 85%. With a nice balance between geothermal, hydroelectric, unusually continuous wind power and some solar, the country has less intermittency of green power than most.
