That’s because nanocellulose is a material with a lot of potential applications – the whiskery, needle-shaped particles are lightweight, stiffer than Kevlar, stronger than steel, non-toxic and, perhaps best of all, completely renewable and biodegradable. What fabric is stronger than … Continue reading →

Alkaline batteries have a higher energy density and longer shelf-life. Voniko AAA bulk batteries are an excellent example of this. With a shelf-life of up to ten years and seven to nine times the power of ordinary carbon batteries, it’s … Continue reading →

Stormbreaker is an enchanted axe of Dwarvian manufacture, forged from Uru on Nidavellir with the ability to summon the Bifrost. After Mjølnir’s destruction, the weapon was used by Thor. Is Thor’s axe stronger than hammer? Although Stormbreaker and Mjolnir have … Continue reading →

A flashing red light is similar to a solid red light in that respect. Because it flashes, however, you can drive through the intersection once the coast is clear, instead of waiting for the light to turn green. In that … Continue reading →

The BMS wake-up circuit is required to restart the BMS when detecting the charger in charging the battery pack. The regular method is spanning the sampling circuit between the battery anode P+ and cathode P−, or connecting a detection circuit … Continue reading →

1.5 volts. AAA, AA, C, D batteries all are rated at 1.5 volts but besides the difference in physical size the amount of electric current they produce is also different. How many volts does a AAA battery put out? 1.5VGenerally, … Continue reading →

Lithium Ion (Li-ion) Lithium Ion (Li-ion) are the new standard for portable power. Li-ion batteries produce the same energy as NiMH but weighs approximately 20%-35% less. They do not suffer significantly from the memory effect unlike their NiMH and Ni-Cd … Continue reading →

Conclusion. The results are likely not surprising. Putting a body skin decal on your metal laptop – even a performant gaming rig – should not cause any changes in system temperatures or even the distribution of that energy. Is it … Continue reading →

In long-term storage applications, a lithium battery should not be stored at 100% SOC, and therefore can be maintained with a full cycle (charged and discharged) once every 6 – 12 months to 30% – 70% SOC. What happens if … Continue reading →

How many times can a car battery be jump-started? It’s OK to jump-start a battery using another car once, but you shouldn’t try to crank it more than three or four times in a row if the dead car isn’t … Continue reading →

Charge Voltage: Most Li-ion batteries perform at their best with a constant float voltage from the DC power supply. For example, a 48 volt Li-ion power plant may have an optimal float voltage of 54.0 volts DC. You can then … Continue reading →

The global solid-state car battery market is dominated by global players such as Toyota Motor Corporation (Japan), Solid Power (US), QuantumScape (US), Samsung SDI (South Korea), LG Chem (South Korea). Which company has the best solid-state battery technology? QuantumScape. QuantumScape … Continue reading →

A 1-square-meter graphene sheet weighs only 0,77 milligrams. It is waterproof, repelling water and corrosion. It is chemically inert, does not react with oxygen in the air and does not oxidize. Can you make clothes out of graphene? New research … Continue reading →

Laptop batteries usually cost a fortune (my 12-inch powerbook battery is like $130). This is why you should take the road less traveled and rebuild your battery. So what do you have to do? Well it s not too complicated, … Continue reading →

A normal amount of parasitic draw for newer cars is between 50-milliamp to 85-milliamp current draw. A normal amount of parasitic draw for older cars is a reading less than 50-milliamp. Anything past these amounts indicates an electrical issue and … Continue reading →
