Analysis of the difference between lithium batteries and lithium batteries

Lithium-ion battery is a metal lithium as the electrode, using electrons to deliver the attack current, prone to dendritic explosion. Lithium-ion battery is a primary battery.

Lithium-ion batteries are lithium ions transferred to the end for charging and discharging, first with lithium ion doped metal oxide as the electrode. Lithium-ion batteries are rechargeable secondary batteries.

The difference between lithium-ion batteries and lithium-ion iron carbonate batteries

Lithium-iron phosphate lithium-ion battery is a lithium-ion battery with lithium iron phosphate as the cathode material. Lithium-ion battery cathode materials are important lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, lithium iron phosphate, etc.. At the same time, lithium cobalt oxide is the anode material for most lithium-ion batteries.


The difference between lithium-ion batteries and storage batteries

First:Comparison of weight. Lithium-ion battery is more concise, lithium-ion battery capacity density is high, reaching 192Wh/kg, the same weight and volume, the energy under load is many times that of lead-acid batteries, now two-wheeled electric vehicles to a large range, only choose lithium-ion battery is the best way.

Second:Charging power comparison. Ternary lithium-ion battery power is higher, 18650 lithium-ion battery, the maximum charging current is 0.5 degrees, generally in 72 years union v24ah lithium-ion battery, the maximum charging current can be 12, of course, lithium-ion battery safety and full consideration, lithium-ion battery protection plate combination constraints, the maximum charging current, now introduced 6 maximum charging current, 72v24ah battery charging as long as 4 hours.

Third: comparison of life. Lithium-ion battery life is longer, general ternary lithium-ion batteries, the number of cycles is about 800 times, according to our current general use of electric vehicles, lithium-ion batteries can be used for at least 3 years. Say 800-cycle does not mean that after 800 times, the battery completely, but after 800 cycles, its capacity can reach 60-70% of the new battery capacity, if the capacity of the range distance can still be higher than the above user's minimum line continuation, it can still continue to use, until the line continuation suspension does not meet the user's want, which may have a figure of four years? In five years? Even six years?

Fourth: Comparison of features and classics. Lithium-ion batteries of the same capacity use more energy than lead-acid batteries. Compare 72V lead-acid and lithium-ion batteries. Typical lead-acid battery operating voltage is 63v-82v, the middle voltage difference is 19v. to north about 72v power lithium for example, 18650 string lithium capacity, single lithium power operating voltage 2.75 - 4.2v, v20 string is 55-84v, in order to protect the safety of lithium and life power, set the operating voltage 58v-83.5v, the center voltage difference is 25.5v, The overall voltage difference is 6.5v than that of lead-acid battery, and it is also said that the operating voltage is 34% more than that of lead-acid plan. Roughly speaking, the range of lithium-ion batteries with the same voltage specification capacity is about one-third longer than that of lead-acid batteries, and the range of lead-acid batteries is only calculated by the energy difference of the batteries, without considering the effect of weight reduction.

The difference between lithium-ion and polymer batteries

Polymer lithium-ion batteries are an upgrade from lithium-ion batteries. Compared with the currently popular lithium-ion batteries, they have the advantages of high capacity, small size (thin) and safety (no explosion). However, their cost (capital) is still relatively high only in high-end digital products (ultra-thin laptops, etc.) due to the replacement needs of the whole industry chain. Lithium polymer batteries are lithium-ion batteries with all-solid or gel over electrolyte. Aluminum-plastic composite film is the commonly used packaging material.

The working principle of lithium-ion batteries, structure, optimal defects and lithium-ion batteries, batteries, lithium-iron carbonate batteries are different, polymer battery series knowledge introduction, the latest news: physicist Gabriel Weiss material called oobleck revelation, successful research claims to prevent lithium-ion batteries new fire chemical formula.
