New grid battery packs record energy density into a shipping container

China leads the world in terms of renewable energy resources like solar power. And not just by a small margin either, making over twice as much solar power as the next highest country, the USA. Where do you store any excess solar energy for use when th… Continue reading New grid battery packs record energy density into a shipping container

Microwave technique recovers 87% of batteries’ lithium in 15 minutes

Lithium is a finite resource, and the more we lock inside rechargeable batteries, the less we have to use. A new speedy method to free the element from such sources could be a game changer in terms of the material’s availability.Continue ReadingCategor… Continue reading Microwave technique recovers 87% of batteries’ lithium in 15 minutes

AI-controlled batteries unlock 10% more capacity and 25% longer life

The AI-BMS-on-chip “unlocks” an additional 10% capacity from a battery and extends the battery’s life by as much as 25%. It does this by monitoring the battery’s State of Health (SoH) and State of Charge (SoC) with a much higher degree of accuracy than… Continue reading AI-controlled batteries unlock 10% more capacity and 25% longer life

CATL’s 1,000-km LFP EV battery super-charges at 1 km/sec

CATL made headlines around the globe last August when it presented the Shenxing battery, an LFP pack capable of adding 400 kilometers (249 miles) of range in a mere 10 minutes at the charger. Not a year later, and that pack’s powering actual cars. This… Continue reading CATL’s 1,000-km LFP EV battery super-charges at 1 km/sec

Why Pulse Current Charging Lithium-Ion Batteries Extends Their Useful Lifespan

For as much capacity lithium-ion batteries have, their useful lifespan is generally measured in the hundreds of cycles. This degradation is caused by the electrodes themselves degrading, including the graphite …read more Continue reading Why Pulse Current Charging Lithium-Ion Batteries Extends Their Useful Lifespan

Self-extinguishing lithium battery puts out its own fires

High-density lithium batteries hold vast amounts of energy – and when they drop their guts, they can do so in absolutely spectacular destructive fashion. So researchers have built fire extinguishing capabilities right into the cells themselves.Continue… Continue reading Self-extinguishing lithium battery puts out its own fires

A simple switch of tape could keep batteries from self-discharging

It never fails … you go to use a device that should be fully charged, but its battery has gone flat over time. Such may soon no longer be the case, however, if battery manufacturers simply start using a different type of adhesive tape.Continue ReadingC… Continue reading A simple switch of tape could keep batteries from self-discharging
