Which Battery is Best for New Energy Vehicle?

Recently, with the promotion of Tesla, more and more new-type batteries for new energy vehicles begin to enter the public consciousness: from hydrogen fuel battery, aluminum battery, to flow battery, grapheme battery, aluminum ion battery, ... It seems that Li-ion battery has been out of date. What on earth is the truth of electric vehicle batteries?

    Now, let’s uncover the truth of electric vehicle batteries.

    Battery is the core problem which limits the development of electric vehicle. For electric vehicles, ideal battery must possess following characteristics:

   1. Enough energy density (has enough capacity at per unit volume and per unit weight), so that the vehicle could run further;

    2. Enough power density (could generate enough power at per unit volume and per unit weight), so that the vehicle could speed up in a short time and achieve climbing;

    3. Fast energy supplements, no matter recharging or replacing;

    4. Low average cost, with competitive advantage on comprehensive analysis of service life and price.

    In current electric vehicle market, there are mainly two kinds of batteries: Li-ion batteries (LFP battery, LMO battery, ternary lithium battery) for high-speed electric vehicles, and lead acid batteries for low speed electric vehicles.

   For Li-ion batteries, the power density and energy density are satisfying, but its recharging time is long and price is relatively high. While for lead acid batteries, although its power density and energy density is relatively low and its recharging rate is slow, its low price result in its extensive application on low-speed and short distance electric vehicles.

   In following passages, we will introduce the advanced batteries mentioned above for you.
