lithium ion battery baby steps: a 3-year-warranty laptop battery

The next-
Generation of lithium
Ion batteries not only power the first wave of electric vehicles, but also transform the power grid;
They will also provide better energy storage for our gadgets and computers.
Venture capital-Mondaybacked lithium-
Leiden energy (Ion battery player)
Used to be called Mobius power)
Alternative lithium is being introduced-
Ion batteries for laptops that do not degrade (
Start losing the full cost of it)
At least three years, and there will be three years. year warranty.
Most standard laptop batteries start to lose the ability to fully charge (
Provide less battery life)
About a year and a half.
Anyone using a laptop knows how annoying it is to have a battery that suddenly cannot be charged for a long time, even though it is still early in the life cycle of the laptop itself.
Leyden Energy said the company\'s battery has the highest energy density and one of the operating times of lithium
Ion laptop batteries on the market, 440 watts per liter, cycle more than 1,000 times, the battery can work at a higher temperature than the traditional battery.
Three of Leyton\'s energy
One year warranty battery will be more expensive than standard battery-
Battery for one year, although Leyden Energy has not yet determined the exact price it will sell the battery, Aakar Patel, CEO and president of Leyden Energy, told me in an interview that a three
Battery costs less than twice a year. year battery.
Leyden Energy will also announce an agreement on Monday to sell its batteries through the Canadian battery retailer Dr.
Batteries, interested customers will be able to purchase batteries online through retailers in a few weeks.
Leyden Energy was founded in 2007 and patented from the chemical giant DuPont for $4.
Investors at Walden International, Lightspeed Venture Partners and Sigma Partners have made a 5 million investment.
Leyden\'s secret sauce is an innovation in the electrolyte part of the battery.
The battery has a positive and negative electrode, and then an electrolyte in the middle, which is the substance that the electrons transfer back and forth when the battery is charged and discharged.
And the standard lithium
Salt for ion batteries-
Leyden uses salt in the base solvent in the electrolyte where degradation begins at temperatures of 70 to 80 degrees Celsius-
The solvent in its electrolyte will not degrade at a temperature of 300 degrees Celsius.
Leyden Energy has the patent for this innovation.
As Patel explained to me, when the battery is charged and discharged, treat the electron as a stick that passes through the electrolyte (
Between the anode and the cathode)
And fill the hole on the other side.
After a period of time, the standard electrolyte, especially at high temperature, starts to break the rod and the hole starts to fill, but Leyden\'s battery can maintain the integrity of these rods and holes at higher temperatures for a longer period of time.
In the grand scheme of innovation, as startups try to change the game with battery design --
Leiden\'s innovation, like baby steps, offers hundreds of miles of power cars.
But if Leyden is able to reach an agreement with major laptop manufacturers to embed the battery directly into the laptop, or sell the battery with a popular laptop, then the company may do a good job.
In 2008, Boston electric launched threeyear-Long lasting lithium
Notebook maker HP\'s ion battery is supported by Oak Investment Partners, Venrock, GGV Capital, and Gabriel risk partners.
Like Boston electric, Leyden Energy has also been focusing on the electric vehicle battery market and working with Brammo to supply batteries to its electric motorcycle Empulse, the original electronic version of brammo is more powerful
Electric Scooter (
I tested it here).
Leyden and a partner from a car manufacturer also received a $2 reward.
The California Energy Commission allocated 96 million yuan to produce 10 electric vehicle batteries per month.
Leiden seems to be paying more attention to the batteries in the laptop and consumer electronics markets than to electric vehicles, as the electric vehicle market seems to be developing at a slower pace than some have expected (
