Lead Carbon Battery: Things a Lay Person Should Know

Lead-Carbon batteries are quite different from other kinds of batteries because they blend up the high energy density of a battery and the high-level specific power of any sort of super-capacitor in a single lower-cost device (even called Pb-C). You can find the trend of using carbon lead battery on the growing side.

The point is lead carbon type of batteries are somewhat deep cycle and even can fully re-charge from 4 to even 10 times faster than regular sort of lead acid batteries (LAB). Lead Carbon Batteries successfully and effectively integrates the high energy density of the lead carbon battery with the proper high specific power of supercapacitors.

In the realm of a lead Carbon battery, carbon is simply added to the negative plate that ends up in a much longer life. In fact, the added carbon simply gives the battery electrode many of the properties of a super-capacitor, which enhances the charge and discharge performance. The partial state of charge (psoc)

) Performance is even much improved, with nearly no sulphation between thirty and seventy percent soc. Sulphation is one of the primary reasons of failure of traditional lead acid batteries and even is generally triggered by partial charging and even ageing. 

If you don’t know, sulphation is when sulphate crystals increase on the negative plate.  In normal usage, most of these crystals get re-absorbed once the battery is charged – however when the battery is simply left in a psoc, some of these crystals attach simply permanently to the negative plate. This in turn diminishes the surface area on the negative plate that in turn simply decreases the capacity of the batteries.

The point is lead -carbon battery is a fresh type of super battery that blends up both lead-acid batteries and even supercapacitors: it not just takes advantage of the instant large-capacity charging of supercapacitors, but even takes up advantage of the particular energy advantages of lead-acid batteries, and has quite Good charging and discharging performance-it may be fully charged in ninety minutes (the life of the lead-acid battery is quite less than thirty times in case it is charged and discharged in this manner).

Lead-carbon batteries are simply different from other kinds of batteries because they blend up the high energy density of a battery and the high specific power of the supercapacitor in a single low-cost type of device. The main aims or goals of lead-carbon research have been to simply extend the cycle lives of lead-acid batteries and even boost or increase their power. Basically, you know what, the developers start with conventional lead-acid chemistry and even add carbon components to the negative electrodes. Though the carbon components do not really alter the basic electrochemistry, they enhance specific power and reduce a chemical reaction known as sulfation that emerges during charging cycles and even is the principal reason ordinary lead-acid batteries fail. Over the last several years, lead-carbon researchers have simply followed three different development paths and these are like:

  • Simply blending carbon additives into the overall lead sulphate paste that gets used for negative electrodes;
  • Simply developing split-electrodes where half of the negative electrode is simply lead and the other half is simply carbon.
  • Then completely replacing the lead-based negative electrode with a proper carbon electrode assembly.

Advantages of Carbon Lead type of Batteries 

The first advantage is fast charging that increases the charging speed by eight times; the second is simply the overall discharge power is increased by three times; the third would be that cycle life is increased to even six times, and the number of overall recharging cycles reaches simply two thousand. Moreover, the cost-effectiveness of this battery is impressive for sure.  The pricing is lower than the price of lead-acid batteries Improved, but you should know that the cycle life is massively improved.

Then if you speak of the safety aspect of batteries, this type of battery is safe and stable to use, and can even be massively used in diverse types of new energy and energy-saving arenas.  In addition, lead-carbon batteries even take advantage of the particular energy advantages of lead-acid batteries, and even have quite good charging and discharging performance-it can be completely charged in ninety minutes (the overall life of lead-acid batteries is less than simply thirty times if charged and discharged in this manner). Moreover, the addition of carbon (graphene) simply averts the sulfation of the negative electrode and even enhance a factor of battery failure.

 The growing technology 

Battery technology has a critical role in the development of energy storage system (ESS). Conventional lead-acid batteries are acknowledged as the pioneer battery technology for standby or even emergency backup power source. Due to the overall constraints of the design chemistry and even use of lead plate components, lead acid battery encounters some or the other types of limitation in cycle life performance. Mostly, it is unable to simply completely address the need for renewable energy projects, rural electrification, even off-grid sites mainly once there are needs for higher daily cycles and fast charging.

The point is with enhancing global demand for renewable sort of energy and continuous expansion of the proper energy storage application, it has forms up proper opportunities for lead-carbon battery that can possibly become another suitable and practical battery choice for ESS apart from lithium-ion batteries and flow batteries technologies. The point is technology owner is seeking collaboration with industry partners to simply take up or adopt the technology and co-develop ESS for specific sort of applications.

Technology Features, Specifications and Advantages

Lead-carbon battery allows for instant high power capacity charging. Blended with secure type of operation typical of lead-acid batteries, it is definitely apt for quick charging operation. It owns great charge and even discharge performance hence enhances the battery state of health and even proper for operation under partial state of charge (PSOC) condition.

The overall Features are:

  • Up to twenty years design life (20oc).
  • Enhanced partial state of charge (PSOC) performance and even cycle life.
  • Brilliant recharge acceptance performance.
  • Lessened negative active plate sulfation.
  • Prolong life of battery cycle  


To sum up, since you know much about the lead carbon battery make sure you speak with the top carbon black lithium battery companies and ensure that you have the best outcomes.
