Honor unveils the first silicon-carbon battery with 12.8% higher energy density

27 February 2023
This is compared to a standard lithium battery that uses a graphite anode and has the same physical size.

Gonna be really interesting how long this one lasts. Silicon doped lithium ion batterys have higher capacity at the expense of lifetime because it expands/contracts more when charging/discharging which compromises the structure (faster)

    Interesting but it remains to be seen of it is indeed better than the current battery found on phones
    Does it overheat ? How fast can it be safely charged ? What are charge cycles until the capacity drops to around 80 percent ? What is the operational range in temperature ? Does it explode or expand like lithium batteries ? is it costly to produce or just as much as current batteries
    Lots of unanswered questions they need to answer

      I'm not able to understand the maths. 12.8% more energy density of 5100 mah would mean something around 612mah, right?
      So, how do we arrive at 5450mah?

      And, how will you check if the Chinese verson is actually hiding a Silicon carbon battery?
      It might employ massive reverse engineering, or in-person size comparison.

Things like this (battery endurance) take time to improve upon, given the constraints that a smartphone places on battery size, given the space available in those sizes of smartphone that sell well.

          imho the problem is not that much a capacity, the problem is the number of recharge cycles/battery deterioration.
          we need longer lasting batteries.
          so far only Oppo has done steps in that direction

              0odle-noodle, 27 Feb 2023Battery technology has come so far as of recent. I remember... moreThat was probably back when phones were much smaller, had headphones sockets and removable batteries (which reduces available space) as standard, smaller screens, and less powerful chipsets... So it's not really down to batteries getting better, but rather down to smartphones changing so drastically that capacity and efficiency have been allowed to increase...

                Meh, this will only serve so that in a few years, apple and Samsung will copy this and take it to mass production!

                  Still not enough, we should be doubling the battery capacity, not this pathetic 12% even then it's not used in real life.

                    Battery technology has come so far as of recent. I remember when a 3,000mAh battery had a similar footprint to a 5,000mAh battery of today. Now the next step is a solid state battery
